Re: Improving Maven Site Docs
Hi, Regarding the XML thing (OT wrt documentation - sorry). XML basically sucks as a human readable format, it's a more verbose form of tree/list syntax (like s-expr). One problem I have with mvn that I don't have with Ant is that there are no 'shorthand' options in mvn ie: to declare a single dependency: dependencies dependency/dependency /dependencies but as I only have 1 I should be able to write dependency/dependency This lack of a 'shorthand' form (for want of a better term), means that a pom file grows to be much larger than necessary (even when I can use a parent pom and inherit from that). Another example is the filtering - this is from a project I'm working on resources resource directorysrc/main/resources/directory filteringtrue/filtering includes include**/hibernate.cfg.xml/include include**/*.properties/include /includes /resource resource directorysrc/main/resources/directory filteringfalse/filtering includes include**/*/include /includes /resource resource directorysrc/test/resources/directory filteringtrue/filtering includes include**/hibernate.cfg.xml/include /includes /resource resource directorysrc/test/resources/directory filteringfalse/filtering includes include**/*/include /includes /resource resource directorysrc/main/webapp/directory filteringtrue/filtering includes include**/context.xml/include /includes /resource resource directorysrc/main/webapp/directory filteringfalse/filtering includes include**/*/include /includes /resource /resources Because we have binary resources (image files) I have to explicitly exclude those from the filtering when I just want to filter 4 files - that's a lot of XML to filter 4 files I guess that this requirement comes from the plexus container, but it's a tangible annoyance that would help to reduce pom complexity if there was a way of fixing it - and yes I know you can use an IDE to simplify/auto-complete writing your pom, but that's irrelevant - I shouldn't have to use an IDE to edit my build/make/pom file - tools are there to make your life easier, they shouldn't be a requirement. Enough moaning, I'll checkout the mvn srcs and start writing javadoc patches etc, maybe I can fix my pet peeves :p Kev - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: filter plugin?
Hi, Is there a plain filter plugin we can use just to do replacements for the templated code at a phase we designate earlier in the lifecycle? We use the ant-run plugin at the gen-sources phase to filter resources before the package phase (when the war plugin executes) Kev - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Why Maven is Hard?
Hi, I've been reading this thread with interest. No it's not a catch 22. I will clarify what I was saying in my other statement. People have exactly 2 choices when faced with a problem such as documentation. The first one is to say, Boy this product is too hard for me to learn and there isn't enough documentation, so I'll go find something else. The second option is to say, Boy this product is hard, but I really think it could help me on my product so I will learn how to use it and ask questions on the list. Then, because I had so much trouble starting, I will recontribute back what I learned to the project. No one is forcing anyone to do anything. That's the beauty and bane of free software. In order for it to be free, someone has to invest THEIR time to provide you the free software. If you don't like it, you can move on without losing a monetary investment. The bane is that because the contributers/developers aren't usually getting paid, they have to have other jobs where they make their living. To demand that they make sure you get the documentation that you want rather than keep up with regular features for others that don't need the documentation isn't fair either. Others like me have been fine without the documentation, so the question is more why have some succeeded and others failed? In my opinion, those that have succeeded with mvn have been 1 of 2 types: 1 - using mvn for simple tasks 2 - mvn developers I currently have a project I'm working on which has a multi-stage build and requires several 3rd-party mvn plugins. Getting this to work correctly has been a nightmare - there's no other way of describing the frustration with the lack of documentation of the core of mvn. Now we also had some specialised requirements (as is often the case), so I've had to write and maintain 4 custom plugins for our build. So from last November (mvn newbie) to now I've done a considerable amount of mvn hacking, including supplying patches for plugins and writing new plugins. mvn internally has appalling docs, there's practically no javadoc in the project - this makes writing patches to mvn itself tedious and frustrating - and *I want to get involved*. For someone who isn't interested in getting involved, but they need to fix a bug in mvn (and yes mvn has bugs), they open the sources and see undocumented code - that's a massive turn off. Perhaps I'm in the minority, but the mvn mailing lists (users/dev) are not the source of answers I thought they would be - I've asked a few questions on how to configure a plugin/build to achieve the output I wanted - and no there wasn't a reply with an answer. Here is an example: The mvn-war-plugin (which combined with the jspc-plugin should allow me to only create a war with .class files (no jsps included)). By default, this plugin includes everything, so setting warSourceExcludes to exclude the jsp files is the solution - except it isn't. If you set warSourceExcludes to exclude the unnecessary jsp files, it still includes the empty dirs that the jsps were in - this makes my war larger than it should be. If I manually specify exactly what to include I get a massive warSourceIncludes section (which must be repeated in each profile as mvn plexus don't support xml entity fragments eg warSources;) I'd like to modify the mvn-war-plugin source to exclude empty dirs, but again the code isn't well documented and I'd have to maintain a custom version of this plugin instead of using the normal one available on ibiblio/maven2 (I already maintain a custom jspc plugin as it's being re-written in groovy at the moment and is dependent on a broken version of ant which has a URI bug) It's a big short sighted to even assume that someone would say, Go pour through the source and write documentation. That's also quite a bit overly dramatic. If I had to pour through source in order to learn how to use Maven, I would have sucked it up and moved on. Welcome to my world - to get anything done (writing mvn plugins, fixing bugs in plugins we use etc), this is exactly what I have to do - and no it isn't overly dramatic, I have to read the src for various plugins and mvn just to work out what is happening as there are no API docs. Often the plugin svn repo has changed location and the site hasn't been updated, so then you have to hunt down the correct svn location using trial and error - again this is a doc issue (jspc plugin had exactly this problem) Once again I reiterate, if you take it step by step then you will be fine. Ant is NOT any easier to create a build system with. In my experience Ant is much more easy to make a build system, but to each his own For non multiproject builds, there is no reason that someone shouldn't be able to read the getting started and have a webapp up in a few minutes. The problem is that people use mvn to begin with, with a simple project and think 'wow it's so easy', then when used in more complex
XML entities or alternative?
Hi, I have a pom with two custom plugin configurations, both of which require access to virtually identical configuration xml. I'd like to be able to declare the common xml in some way I've tried using xml entities !DOCTYPE project [ !ENTITY config config goes here... ] config; But this fails with a XppPullparserException I've also tried using a property to hold the escaped xml, but this fails as the escaped version isn't parsed correctly Is there any mechanism in mvn2 to allow the re-use of arbitrary xml snippets within the same pom (and no I cannot put common stuff in a parent pom, this isn't an option right now) Thanks, Kev - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Access command line args in a unit test
Hi all, I have a utility class that is tested via a Test class via surefire/junit4. I want to test if the parameter -o has been passed as a command to the maven command line. Prior versions of mvn allowed me to access the args via : System.getenv(MAVEN_COMMAND_LINE_ARGS) (on windows) or System.getenv(QUOTED_ARGS) on linux (why do the launch scripts for the two platforms use different variable names?) The problem now is that since the release of 2.0.6, the QUOTED_ARGS value is no longer being exported in the mvn shell script. As this wasn't mentioned in the release notes for mvn2.0.6, I have now to build a workaround so that should the maven team decide to randomly change the shell scripts and batch files, I have a more robust solution in place that won't break. Is there any other way of getting access to the command line args from a class without going through the System.getenv - so far I've found no way of accessing the -o value that I pass in on mvn2.0.6. Any hints/advice welcome. Thanks, Kev - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: ant scp task in maven2
Hi,
I need some help. I tried to include the Ant task scp in my Maven2 pom.xml
by defining taskdef name=scp classname=com.jcraft.jsch.JSch / using
the maven-antrun-plugin. But it doesn't work Embedded error: No public
execute() in class com.jcraft.jsch.JSch. If you want to start this task in
ant you simple have to copy the jsch-version.jar in your local ant/lib
directory and the scp task becomes available. What have I to do to get it
work in Maven2. I need this task to secure copy files from a local machine
to a remote linux machine.
I did this like so:
plugin
groupIdorg.apache.maven.plugins/groupId
artifactIdmaven-antrun-plugin/artifactId
executions
execution
goals
goalrun/goal
/goals
/execution
/executions
configuration
tasks
!-- read in build.xml --
ant antFile=build.xml target=/
/tasks
/configuration
/plugin
Then for the jsch stuff I used maven to manage it (downloading etc)
and then in the ant file I used an ant target to get the ant-jsch.jar
file and then used taskdef to define it - note that Ant hates having
a copy of the jar in your classpath and a copy in ANT_HOME/lib:
target name=init
!-- Sanity check for delegating classloader problems --
available property=ant-jsch.present
file=${ant.home}/lib/ant-jsch.jar/
fail if=ant-jsch.present message=Please remove ant-jsch.jar
from ANT_HOME/lib see [
http://ant.apache.org/faq.html#delegating-classloader ]/
path id=jsch.path
pathelement location=${src.tools.dir}/jsch/ant-jsch.jar
/
pathelement
location=${src.tools.dir}/jsch/jsch-0.1.24.jar /
/path
taskdef name=scp
classname=org.apache.tools.ant.taskdefs.optional.ssh.Scp
classpathref=jsch.path /
taskdef name=sshexec
classname=org.apache.tools.ant.taskdefs.optional.ssh.SSHExec
classpathref=jsch.path /
macrodef name=ssh-cmd
attribute name=command/
attribute name=fail default=true/
sequential
sshexec
host=${deploy.machine.address}
port=${deploy.machine.ssh.port}
username=root
password=${deploy.machine.root.user.password}
command=@{command}
failonerror=@{fail}
trust=true/
/sequential
/macrodef
/target
Getting the repo is easy enough through ant ${user.home}/.m2/repository/...
And in your pom.xml you declare the dependency on ant and antjsch

${project.profiles}
Hi ,
I want to get access to the value of the activeProfile
For example :
mvn -P dev clean package
in my pom.xml I want to pass 'dev' to antrun without specifying it
twice (ie as a -D property on the command line)
I can get access to a List/Array of Profile with ${project.profiles}
plugin
groupIdorg.apache.maven.plugins/groupId
artifactIdmaven-antrun-plugin/artifactId
configuration
tasks
property name=mvn.repo value=${user.home}/.m2/repository/
ant antFile=build.xml target=${project.profiles}/
/tasks
/configuration
/plugin
but I want to be able to do either:
${project.profiles[0].id}
or
${project.activeProfile}
so that I can get the value of the currently running profile
Thanks

Re: Maven Ant Task problem when used with Ant 1.7.0
Hi, !-- But the following task throws a NullPointerException -- pathconvert property=echo.dependency.files refid=dependency.files/ Are the maven ant task supposed to work with the last Ant 1.7.0 version ? Any idea about what causes this problem ? Ant 1.7 introduced the concept of ResourceCollections, this code would have affected filesets, but I cannot diagnose the problem further without a full stack trace from you NullPointerException.

Shortening command lines with profiles?
Hi all, I currently have a mvn command line which is fairly long eg: mvn clean compile war:inplace tomcat:inplace Is it possible to use a profile to reduce this to something like: mvn -P local-deploy where I can specify the exact goals in the profile instead of on the command line?

Re: tomcat deployer
Hi, This gets discussed fairly regularly and there's multiple ways to handle it. If you're not aware, there's a great search engine for this list at http://www.nabble.com/Maven---Users-f178.html I actually find Nabble to be close to useless as it doesn't seem to get spidered by google properly, certainly MARC is my preferred place to find stuff out - shame maven list isn't there :( The way I've setup things I can see the changed jsp without calling any maven target. There's more details of my solution here http://www.nabble.com/Eclipse-war-builder-tf2371898s177.html#a6646490 Another fellow wrote a custom eclipse plugin to help him. Could you go into more details? I've followed what I could from your post ^^ but I still cannot get Tomcat to deploy just the context.xml file and use the target directory as an exploded webapp. My guess is that I've setup tomcat incorrectly, but a working example of what to do would be great (I also tried the eclipse war builder thing and again it didn't work for me).

tomcat deployer
Hi all, I'm trying to work on a webapp with tomcat and mvn. I want to be able to edit a jsp, type mvn tomcat:redeploy and have just the changed jsp be reloaded, without having to compile/package/deploy I'm fairly sure that this is possible using a combination of mvn + tomcat-plugin, but I'm failing the correct incantation test so far I can do a mvn tomcat:deploy, but this compiles/filters/packages and takes forever - not good for rapid development of ui stuff mvn tomcat:redeploy seems to just redeploy the application that's already deployed in the CATALINA_HOME/webapps directory, what I need is some way to configure the plugin to deploy my development directory as an exploded web application Thanks in advance for any/all help Kev - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Overview - Ant to Maven
for deploying have a look at cargo at: http://cargo.codehaus.org/ I have used the cargo plugin and the tomcat plugin and both of them have a flaw if you are deploying to a remote server (ie one without maven installed on it). When they deploy, they first undeploy your application, then they copy the war file over from your client to the server, then they deploy the new war file (just copied over). This is ok if you have a fast connection between the client machine (running maven) and the server (running tomcat). But if you are doing this over the internet, the time you application is offline can be quite long as you must wait for the whole war file to be copied over while your app isn't available.

M2 Cargo plugin now found...
Hi all, The problem I just spent 2 hours banging my head against was related to where I declared the cargo-maven2-plugin Declare the plugin under plugins and it downloads fine, declare it under reportingplugins and you get *NO* information about why it won't download I'd like to suggest to any mvn2 devs lurking that some kind of error/info message be displayed if the result of a build is failure and the reason is that a plugin couldn't be found. Perhaps: Failure [Build Error] xxx-plugin could not be found : Have you checked to ensure that you have declared it under plugins not reportingplugins ?
