Webapp classpath issues in multi-module project
Hi, We have a Maven project that is laid out as ./domainModule ./serviceModule ./baseModule (with parent pom) ./webAppModule ./module4 We can successfully generate eclipse projects for the module using mvn eclipse:eclipse from the baseModule which sets up the classpath correctly in eclipse with the separate eclipse projects depending on each other correctly. The classes in the webAppModule are able to see the classes from other modules within the development environment. However when we try to run the webapp within Eclipse, we get ClassNotFoundExceptions when the code attempts to reference our classes which are in the domainModule or serviceModule. Strangely enough if I run mvn eclipse:eclipse from the webAppModule directory so that the eclipse project has dependencies on the snapshot jars in the local repo then the exact same code in the webAppModule works fine. It seems the problem is to do with eclipse resolving the classpath dependencies on other projects, not really a Maven issue but I'm at a loss as to where else to pose this question. Any ideas? I'm using eclipse 3.4 I've configured wtp as follows: plugin groupIdorg.apache.maven.plugins/groupId artifactIdmaven-eclipse-plugin/artifactId configuration downloadSourcestrue/downloadSources wtpversion2.0/wtpversion /configuration /plugin Cheers, Ian
Re: Problem while building using Maven
There is a very quick tutorial on the Maven site which should get you up and running with a very basic pom file and standardised directory structure. You can find it here: http://maven.apache.org/guides/getting-started/maven-in-five-minutes.html You don't actually need a settings.xml file to run Maven so I would suggest that you delete/move the one you have created and go through the tutorial. Once you have finished that you will have a Maven project which will retrieve your dependencies from the main Maven site. It will then be easy to create a settings.xml file to use your Nexus repository. If you have problems, you will need to post the details of the error message that you receive.

Re: Problem while building using Maven
Hi, Yes indeed. If your Nexus instance is correctly configured and you are pointing Maven at it correctly then the artifacts corresponding to the dependencies listed in your pom should be downloaded and put in your local repository. 1) Can you confirm whether you have added a dependency to your pom which includes the commons codec classes that you are using? 2) Can you please attach a copy of your settings.xml file 3) With regards to these artifacts that you have installed, are they publicly available jars which can be found on the central repo or jars that you have created yourself? 4) If you run 'mvn -U compile' it forces a check for updates on your dependencies. What output do you get when you do this? Is it able to succesfully connect to your Nexus instance?

Re: Problem while building using Maven
What do you change in the code to make it stop working? Could you include a full transcript of what Maven logs when you encounter this error? Also, do you need to use that proxy you have defined in the settings.xml? One more thing, in your pom.xml you have defined your repo, but you have defined it again in the settings.xml file in a profile called 'dev'. Do you only want to use this repo under certain conditions or do you want to use it the whole time?

Re: Functional Test strategies with Maven
Hi Martin, What is the reasoning beyond the separation of the functional tests? Is it because you would like to run them separately from your other unit tests?

Re: Re: Functional Test strategies with Maven
Are these functional tests invoked as jUnit / TestNG tests? I have written similar, integration type functional tests with mocks, but they were still based on jUnit / TestNG. I simply stored them in the same module name--test--src--java are being used for unit tests. I differentated between the two sets through the package names and used profiles to run these optionally. My reasoning was that its easiest to stick with the vanilla Maven directory structure as it is a standard. This approach certainly worked for me at the time. I guess that would be my suggestion. ps: I think you replied directly to me, rather reply to the group email address.

The specific purpose in this case is to ensure that we've wired up messaging flow(s) within our module. This is done by sending a mocked event through the various routers/transformers etc that we have. They're not unit tests because they're not testing a discrete bit of functionality within a Java class. However, it is vital that these tests pass before we package that module, so I we want to run them as part of a the test life-cycle (as opposed to integration-test which is post package) or at least a life-cycle phase that is before package. I agree that we could use profiles to run this group of tests separately, but I'd like to understand where they should live in the source structure. All of the Maven literature that I have read talks of module name--test--src--java being used for unit tests, but tests such as mine fall into a grey area?

Re: example for settings.xml
Ratna, Now that you have a better understanding of the settings.xml file, I would recommend that you specify a mirror for the main maven site that is located close to you geographically. Encourage the rest of your team to do the same, or even think about putting in a local repository for your organisation. Your Maven will run faster due to a lower latency connection and you'll be less load on the Maven servers.

Re: Un-mavenize a Maven2 project ?
Hi Alessio, A possible solution to your problem that would allow you to keep your mavenised project and isolate your students from Maven would be: 1) Generate an eclipse project using Maven 2) Create a lib folder in your project structure (at the same level as src) 3) Manually or automatically copy the the project dependencies from your local repo into the lib folder (maintaining their relative directory structures) 4) Distribute the project to your students. Each of them will have to use the 'Import existing eclipse project' option to get it into their workspace. 5) All of the project dependencies are mapped relative to the M2_REPO variable, so your students would have to create this variable and then point it at the lib folder containing the dependencies. By this point they should be up and running and ready to code. I haven't tried this but I think it should work fine. You could also distribute the lib folder seperately to the project if you preferred that.

We converted many of our projects from Ant to Maven, but still have both the build.xml and pom.xml in the root directory. I even removed the third party jars from our repository. Instead, I added Ant's get task to the build.xml to fetch the needed jars. It is up to the tech leads to decide whether to use Maven or Ant in our continuous build process although more and more projects are now being built with Maven. Then again, installed Maven, set the settings.xml in the Maven directory, then tarred it up and pass it out to the students. It's pretty self contained. All they need to do is untar it somewhere, and put a link to the mvn script into their PATH. That will allow the students to learn Maven while they are at it. Might as well let your students learn how to use Maven now while their brains are still soft and moist rather than wait a few years after brain hardening has started to set in.

Re: Mavenizing existing project
Hi Steve, I use Maven for building my projects and the eclipse WTP plugin as well. JSP re-compilation while running and hot swap code replacement while debugging has always worked for me.

I have one more question I meant to ask earlier but forgot. I do make use of the Eclipse WTP environment and a local Tomcat server and immediate compilation to create a rapid-turnaround development environment apart from the server. This dovetails pretty nicely with the regular Eclipse export. Is it possible to still do this when Maven is running the show? Stephen Connolly wrote: 2009/2/22 Steve Cohen sco...@javactivity.org I am consideringMavenizing a pre-existing project. This project consists of a Web Application (WAR file) and a server side JAR module, built from several Eclipse projects, some of which are dependencies of both modules, as well as many third party jars, both open source (many of which themselves use Maven, of course) and proprietary. Current build process is very rudimentary. The Eclipse projects do not currently use Maven naming standards for directories. To do builds, the simple Eclipse Export menu options are currently used. Deployment is manual and there are FYI, maven's lifecycle says *nothing* about deploying post release. When maven talks about deploying, this is deploying the released artifacts to a Maven repository. There are maven plugins to deploy your war to tomcat, jetty, etc... but they are not part of the lifecycle... I think you will always end up with a manual deployment step (even if that is running a maven mojo in tomcat-maven-plugin, cargo-maven-plugin, jetty-maven-plugin, etc) And your customers will have the same... On the other hand, if deployment is for integration testing, then maven can do even better, with the ability to start and stop the app server before and after the integration tests (as part of the lifecycle). Some aspects of the maven support for this are poorer than they could be though. some annoying manual post-export tasks that must be run. Version control uses subversion, including a big ugly project containing static copies of binary jars. These are my main reasons for considering conversion to Maven. Questions: 1. Are there articles around detailing war stories about making the kind of move I am contemplating? I would like to read such before I get started. I have just purchased Maven: The Definitive Guide, and while the information there is very good, it tends to assume a start from scratch. I would like to keep the history in the Subversion respository if possible. I have done several conversions, and providing you rename and move the files in subversion, you can keep your history without issue. 2. Would I be better served by renaming directories at the start to Maven Convention over Configuration standards or by overrriding the defaults all the way down the line? Yes. This is the way I recommend myself. There are two ways you can do this... 1. Make the changes in trunk, and keep the existing build process functional while you change everything... this allows you to ignore maven until you get everything perfect. 2. Make the changes in a branch and merge them back when you're ready... I'd want to be on subversion 1.5.5 before trying that of course if you are using subversion 1.5.x and have repository access via http or https you will have a bit of fun when releasing using the release plugin. svn: does not have these issues. (A bug the mod_dav_svn prevents tagging from a working copy that is not based off of the head revision) 3. Would I be better off building a local network repository containing both the open source and proprietary code needed or would it be better to create a local repository only for the proprietary stuff and get the open source stuff from a remote repository. You would be best served using nexus to host your artifacts and cache all the remote ones. There are alternatives, but Nexus is, IMHO, the easiest to set up and get running, and also has the lowest cost of switching to the others (i.e. all the data is on the disk) (Note I have no affiliation with either Nexus or Sonatype ) Thanks.

Build time resolution of properties files
Hi, I'm trying to build a WAR which includes a properties file at build time. This properties file will vary according to the environment that it is being built for. (dev, test, prod). This would ideally be added during something like the process-resources stage, so that I can point my eclipse project at various environments. I've tried adding profiles to the project which specify an additional resource area where the property file can be pulled from. ie (src/main/properties/dev and src/main/properties/test). This works fine the first time I build my war and the correct properties file for the profile is included. However when I try to do it again with a different profile, the properties file is not replaced. Instead the properties file (from the previous build) is incorporated into the build. The only way to get it to work properly every time is to run mvn clean every time. At the moment, I've figured out another way where I use the ant runner to copy the desired properties file into src/main/resources. Is there a better way for me to do this. ps: The properties files all have the same name, but thats necessary as the application picking them up has this name hard-coded into its config.
