Is it possible to build(and not download) a dependency in same pom.xml?
Another team builds/maintains a code in git repo A. I have to use that as a library in my code.
When I build my code using maven, I want this to be checked out and built and then the jar be included as a dependency.
I understand this can be achieved using Jenkins jobs.
And in dev stage, I can install an already built jar in m2 repo and use the jar as dependency.
However, I would want to confirm if its possible to solve this scenario outside Jenkins. That is, I as a developer, can I configure the build of repo A during build my code?
I hope I am able to explain the scenario.
Thanks.

I have a maven project on my local system, but I created a freestyle project in jenkins and gave its the workspace directory as of my project.
Being new to jenkins, I am wondering how to add maven repository jars to a freestyle project's classpath while writing its batch file to execute the project, in such a way that all the jars which are in recursive directories
C:\users\xyz\.m2\repository\*
come in the path while building the project. I don't know whether it is possible or not without any hassle, but when we create a maven project in jenkins it automatically takes all the repository jars in the build path. So there must be a way around rather than putting those libraries manually into the build path. I have searched so much on google but nothing popped up.
Any input would be appreciated.
Thanks
I recommend you to use EnvInject Plugin. This will prepare environment to be built before the job run. So in your case adding the path can also be done using this one. If you are running the jenkins on windows machine, doing this will do the trick. Or if you are running on Linux please feel free to explore or comment here again.
I have a multi module maven project ('assembler'), and I would like to add a FindBugs phase.
The problem is that some of the projects are not able to build stand alone since have dependencies on other projects... however when I invoke mvn package from the 'assembler' project - it works fine and all inner dependencies are resolved.
The problem is that when mvn findbugs:findbugs command is executed, those inner dependencies are not resolved, and maven complains.
Searching Google, I found a way to make it work, using mvn install, but I do not like this approach since eventually this should be used in CI with Jenkins and I do not want to rely on local maven repo on the build server.
Will appreciate hearing your ideas.
Thanks.
Don't be afraid of mvn install, it is your friend. What you need is to set up a centralized Maven repository (such as Nexus or Artifactory) or rent one (such as Bintray) to which you deploy your Maven artifacts to.
Jenkins or any other decent CI engine can do the actual deploying for you, either natively or through Maven. Once deployed, other users - Jenkins included - will be able to resolve their dependencies and you will be able to run FindBugs, PMD, JaCoco, host Javadoc or pretty much anything you want.
Side-note: Don't get confused by the term deploy as most people new to Maven usually get. In context of Maven, it has absolutely nothing to with your target environment. It simply means that an artifact is pushed out to a remote repository and nothing else.
Are there any plugins or ways to download the dependencies for a maven project from Jenkins? I am using Jenkins for a multi-module desktop application. Although I know I could just archive all dependencies, I don't see why there isn't the ability to download dependencies using maven which installed on the same machine as Jenkins. Preferably one would specify the location of a pom and then have the ability with one click to download all the dependencies for that pom. Can you do this? I do not need or want an entire binary repository for this feature.
Edit: I will try and rephrase this as I don't think people are understanding.
In Jenkins one has the ability to archive artifacts at the end of a build. Also in jenkins you have integration with maven. When building a jar in maven you have arguablly 2 options:
You can either use the assembly plugin which zips all .class files
together with those produced from your source code resulting in 1 jar
You can create a jar just source code which references all
dependency jars which are located in a separate folder.
In Jenkins one also has the ability to download the latest artifact. Now if I am using Option 2, I can either archieve just the jar which my sources produced, which I would say is more desirable for space and is the whole purpose of the archive functionality, or you can also archive the libraries too.
Here is the PROBLEM!! If I don't archive the libraries then I cannot easily run this jar, as it is a desktop application and its dependencies cannot be obtained in the same mannor as clicking on a link from jenkins. So lets say my question is what is the easiest way to obtain them? Extra info: assume jenkins is running as a server and you can't use artifactory or another server application, that seems to me to be massive over kill.
Use the maven plugin and create a maven job for your project. Jenkins will then use the maven command you provide in the job configuration to build the project. This means maven will download the projects dependencies and store them on the machine jenkins is running. Normally this would be <JENKINS_HOME>/.m2/repository. This way you get a local repository that only contains the dependencies of the projects you created maven jobs for.
I have a maven multi module project with several modules. I want to deploy them (mvn deploy) only if they all pass a full mvn install (which includes the tests).
Currently, I run a mvn install on the project. If all modules pass, I run mvn deploy to do the deployment. The problem I see is the waste of time calling mvn twice (even if I skip tests on the second run).
Does anyone have an idea on this?
EDIT: I have learned that using Artifactory as a repository manager and the maven-artifactory-plugin with your maven setup will add the atomic deploy behaviour to the mvn deploy command. See the Build Integration section in the Artifactory documentation.
[DISCLOSURE - I'm associated with JFrog. Artifactory creator.]
Take a look at the deployAtEnd parameter of Maven Deployment plugin: http://maven.apache.org/plugins/maven-deploy-plugin/deploy-mojo.html
This is a bit tricky. Maven is not atomic when it executes the build life-cycle. So a broken set of artifacts may end up in a repository.
One solution I know is Nexus Pro: http://www.sonatype.com/Products/Nexus-Professional/Features - it allows you to promote builds or define certain repos as staging. So only verified versions get promoted to be used. Maybe artifactory has something similar - I just don't know.
If that solution is too expensive you probably need to create a cleanup build or profile to remove artifacts that where already uploaded. My first guess would be to write a Maven plugin to use the the proxy remote API or maybe the maven features are already sufficient. But since deploy means update the meta-data xml files too I dont think there is a delete - not sure on this either.
I want to share all the External Jars currently being managed by MAVEN with my other team members. I am using Mercurial as my SCM and i am trying to figure what is the easiest way to commit my entire project (include libs) to a repository so that my team members can clone and get running without severe eclipse configuration?
Maven is there in order to help you retrieving libraries. So that, all you have to do is to commit all your files including the pom.xml (.hg should contains everything in target, and other unrelevant files)
Then your project members can pull the sources and run mvn eclipse:eclipse (see eclipse & maven.
And finally import the project in Eclipse.
That was is they need sources...
If they only need the jars, you must put in your infrastructure a company repo that will handle your deployment using mvn deploy. Some information there maven repo::Intro, take special care at the wagon you could use (ftp, ...)
This way, when you're done with your devel and you have pushed your code, you just have to deploy the jar on your repo.
Doing so, your project member'll have to run mvn -U eclipse:eclipse or any goal to update their local repository with your lastest deployed version.
