You wont regret it. Thank you. I can do it, for sure. I tend to read the docs and ask questions at the same time, until I get my problem solved. The issue is that these problems are peripheral to the problems I want to solve, which is a secure promise-based distributed object messaging system. Much more interesting and difficult in its own right. This stuff, while very powerful when done right, and necessary, is like keeping my apartment clean or cooking dinner!

RE: can I run mvn install with no verify phase?
Thanks for your help. I did some O'Reilly reading. I could not find that I could skip the verify, but as Robert mentioned I can control the threshold of the plugins. I now have: workspace/ pom.xml murmur-events/ pom.xml murmur-utils/ pom.xml reed-solomon/ pom.xml murmur/ pom.xml genesis/ pom.xml where the reed-solomon overrides the plugin values for the analysis tools. It is fairly complicated to setup each new project, since I need to combine maven3, git, eclipse, and a Jenkins project for each one. I had to generate the top and put it into the Jenkins repository, which is separate than the .m2 repository, but it works. I may switch to a public repository at some point. Anyways, once I get each project setup, it is gravy.

Rob, please read the maven books. Your questions are showing you need to grasp the basics first. You will save yourself lots of pain. From: Robert Scholte [mailto:rfscho...@apache.org] Can you reach the age of 100 without ever being 99? You must find your solution in the plugin bound to the verify-phase. A strategy could be to make add a profile with the ITs. profile idrun-its/id /profile If you want it to be executed by default, add this kind of activation: activation property nameskipTests/name value!true/value /property /activation So mvn install -DskipTests=true will indeed skip the tests Otherwise activate it by id (that is: -Prun-its) Robert On Sat, 06 Oct 2012 12:44:36 +0200 Rob Withers reefed...@gmail.com wrote: As the subject asks: can I run mvn install with a no verify flag to skip the verify phase?

For more de tails see:C:\rob\comp\workspace\murmur-events\target\pmd.xml - [Help 1] Right... one fix would be to fix those 17 PMD violations...;-) Alternatively you can remove maven-pmd-plugin from the plugins section of the murmur-events/pom.xml. Or you can use that same entry to configure the maven-pmd-plugin to be less strict (not sure if that's possible...?). Exactly, I reduced the strictness. The violations were not preventing compilation. I want to be able to install if it runs, then browse the violations and fix those that make sense. I have one method that increments a parameter and I don't want to fix that for clarity, for example. 5.. If the jar is named ‘murmur-events-1.0.1-SNAPSHOT.jar’, will the above dependency of the following find it? Um... not sure I understood that...? This dependency section in the murmur pom: dependency groupIdorg.reefedjib/groupId artifactIdmurmur-events/artifactId version1.0.1-SNAPSHOT/version /dependency If that is the groupId+artifactId+version your actual murmur-events pom.xml has, and if murmur-events have been built and installed in your local repository, then yes, that shoud be enough. Yep, it all works now. 6.. What about setting up an internal repository? Would that be a better solution? What do you mean by an internal repository? A repository for internal to your project? Or a repository local to your site? Instead of a local repository, have a public repository at http://callistosheart.org/maven or something. If that is an option for you, then I'm sure it will be a good thing. I have only ever been allowed to set up an intranet repository...:-) You can add that repository in your top pom. So, how does this work? What does the site file structure look like? 7.. If I have the dependency in maven, will eclipse pick it up? Not eclipse by itself. But you can either use the eclipse m2e plugin that will make maven projects appear as eclipse projects, or you can use the maven- eclipse-plugin to let maven generate the eclipse project settings. You can also use maven as an external build tool in eclipse. Does Eclipse Juno include these plugins? m2e? By default? No idea. It does have some level of support, but I am finding I need to go to the command line to generate new projects. That isn't m2e or eclipse. That's the maven-eclipse-plugin. If you do mvn eclipse:eclipse on the workspace level this maven plugin will generate the eclipse project files/directories in murmur-events and murmur. The dependency from murmur to murmur-events will be a project dependency. Note that you also need to mvn eclipse:configure-workspace on the workspace level before starting eclipse. This will set the M2_REPO eclipse variable, pointing to your local repository. Very cool. Thinking about this, I think I will establish a sample project with everything and just copy it over to new projects I want to create and update the artifactId in the pom. This way I can have all my default dependencies setup. Hm... OK. Maybe my test project can help you a little bit. You can just start out with the project and verify that it builds, then add stuff and test builds and if it breaks figure out what makes it break Attached is the output from me doing mvn install on the test project. I included several dependencies in the top and then overrode some of the analysis dependencies in the one sub to be even less strict than the top. Works like grace.

noob confusion about dependencies and repositories
Hey y’all, I am trying to link one project’s jar to another project. I am totally confused and hope someone can take some time to explain. I have been reading the following pages on the site: http://maven.apache.org/guides/introduction/introduction-to-dependency-mechanism.html http://maven.apache.org/guides/getting-started/index.html#How_do_I_create_a_JAR_and_install_it_in_my_local_repository http://maven.apache.org/guides/introduction/introduction-to-repositories.html I have the following tools: a.. eclipse b.. maven c.. git d.. jenkins e.. findbugs f.. pmd my two projects are murmur-events and the other is murmur. Murmur has a dependency to murmur-events. My murmur-events pom has pmd and findbugs and failures in the mojo s preventing installation of the jar. Here is the dependency in the murmur pom: dependency groupIdmurmur-events/groupId artifactIdmurmur-events/artifactId scoperuntime/scope version1.0.1-SNAPSHOT/version /dependency Here are my questions, I suppose: 1.. How can I install murmur-events, even though pmd/findbugs is issuing warnings? The mvn install is failing. 2.. Where is the local repository where these get installed? 3.. Do I need to have a parent pom with two modules, one for each project? Does this impact where my local repository is? 4.. Should I specify the murmur-events-1.0.1-SNAPSHOT.jar, as a dependency in the murmur project, by system file path? 5.. If the jar is named ‘murmur-events-1.0.1-SNAPSHOT.jar’, will the above dependency of the following find it? 6.. What about setting up an internal repository? Would that be a better solution? 7..
