I have several modules that I build in a maven multi module project. I can call maven on the head pom.xml in the parent directory and build all modules. However, Jenkins only builds the first module of several svn repos I have configured by calling mvn -f <first child module it sees>, and never builds the other child modules. I tried creating a new Jenkins project, but the same problem occurs.
In the Advanced section of the maven configuration block, are you definitely pointing at the parent pom? Jenkins only executes maven once, against the pom specified in this section.

I have a big local maven project that contains multiple modules which are inturn maven projects and are dependent on one another.
Ex.
parent pom.xml
<pom>
<module1> #jar
<module2> #dependent_on_module1.jar
<module3> #
</pom>
I have mentioned the sequence to build those modules in the parent pom.xml .
I also mentioned where to place the artifacts when they're built in groudId and artifactId.
But in the dependencies for all those modules, I have mentioned a common local system path for all those modules.
Is there any way to copy all the artifacts which are being created for modules when maven build is performed on the parent pom to a specific directory that can be dynamically mentioned when the maven command is run.
I have searched for maven copy command. But looks like it's not going to do what I want.
Any suggestions?
I cloned the git repository of Apache ActiveMQ Artemis project (https://github.com/apache/activemq-artemis) and then typed
mvn -Ptests test -pl :integration-tests
I was surprised to see log messages like the following
...
Downloading: http://repository.apache.org/snapshots/org/apache/activemq/artemis-selector/1.4.0-SNAPSHOT/artemis-selector-1.4.0-20160625.030221-11.jar
Downloading: http://repository.apache.org/snapshots/org/apache/activemq/artemis-core-client/1.4.0-SNAPSHOT/artemis-core-client-1.4.0-20160625.030211-11.jar
...
Since e.g. artemis-core-client is contained in the git repository I cloned in the beginning, I'd have expected maven just builds it from there.
That way, when I make changes in the core client source, they get picked up by the integration tests.
Instead, maven is downloading the jar from the repository.
Question: How do I configure maven to always build all modules that are in the git repository and download only "true" dependencies, which I mean things not in the git repository?
You are not executing the Maven build on the main project, on the main pom.xml which indeed defines the artemis-selector and artemis-core-client modules, among others.
You are executing the Maven build on the tests and its pom.xml, where only tests modules are defined. This is a side/test project, which has as parent the previous pom file, but it doesn't play any role in its parent modules definition. Hence, dependencies are not resolved as modules but as Maven dependencies.
You should firstly install (via mvn clean install) the former project, so that libraries will be available in your local Maven cache (hence no downloading would be triggered), then execute the tests project.
Check the Maven docs for a inheritance vs aggregation difference to further clarify it.

I have a plugin which can run either using a pom.xml or without (depends upon the version of the artifact we're building: new versions go without a pom. Strange, I know).
I want to have that plugin run in Jenkins.
But when creating a maven project, I have to set a pom (or as a default, Jenkins suppose there is one in the base folder given).
Question: Is it possible to configure Jenkins to not use a pom when there is none?
As per my comment, you should use a Jenkins freestyle project build in this case, in order to have more flexibility and avoid the default assumptions of a Jenkins Maven build.
In such a build, you can then configure a build step executing a shell or a Windows command (depending on the Jenkins server OS).
Indeed, in the Jenkins Maven build, a pom file is always required, as mentioned in the help support of the Configuration > Build > Root Pom entry
If your workspace has the top-level pom.xml in somewhere other than the 1st module's root directory, specify the path (relative to the module root) here, such as parent/pom.xml.
If left empty, defaults to pom.xml
how to run only specific maven module from maven eclipse project.
I have few modules in my EAR maven project and when I build whole project it fails at one module WAR,saying this war artifact module not found in repository.
Your multi module project must e having a common parent. First install that parent pom in your local repository. Now go to child module project and maven build the project.
It should work given that all its dependencies are present.
I have successfully imported a parent pom with child modules into IntelliJ. The child modules have dependencies between themselves and IntelliJ has correctly set up the classpaths so that changes to module A are reflected in module B. However these dependencies are not maintained when I execute a maven goal in IntelliJ (compile, jetty:run etc). Here is my structure:
client_libs
-- servlet-filter
-- filter-example
filter-example depends on servlet-filter. However when I run maven compile on filter-example I get:
The POM for com.cloudseal.client:servlet-filter:jar:1.0-SNAPSHOT is missing, no dependency information available
I can work around this by manually installing servlet-filter into my local repo before I execute a maven goal but obviously this is not ideal. How can I get IntelliJ to maintain the relationships between the modules when I execute a maven goal?
You shall be able to just run mvn package but from place/path where your parent pom is.
If this's not working for you, please post your pom.xml files.
