I have a root parent maven module which has lot of sub-modules that build jar files as artifacts.
I cannot change all sub-module pom.xml files.
From the root parent pom.xml is there a way I can get a list of all jars (artifacts) built by sub-modules?
Preferably after the package phase is complete?
PS: As a part of root module build I want to generate a report using a tool which requires this list of jar files.
There's a target/maven-status/maven-compiler-plugin/compile/default-compile/createdFiles.lst in a Maven project.
You can use the GMavenPlus Plugin and Walking the File Tree to gather these files and put their content where you want.
Another option is to develop an own Maven plugin that does the same.

I a maven rookie and am wondering how to get a binary jar file if it is not already in the repo. Specifically i'm in need of: jackson-dataformats-text-2.13.0.jar. Do I need to build it myself? I'm used to creating a project and marking a library as a dependency and seeing the jar downloaded into my .m2 cache but all i see in my cache is:
jchan#jchan-Z170N:~/.m2/repository/com/fasterxml/jackson/dataformat/jackson-dataformats-text/2.13.0$ ls
jackson-dataformats-text-2.13.0.jar.lastUpdated jackson-dataformats-text-2.13.0.pom.sha1
jackson-dataformats-text-2.13.0.pom _remote.repositories
Can someone advise how I am to get a built version of the jar from maven central?
We are still maintaining our ant build and I need the jar file for this. (i know i know, ancient stuff but team is not ready to port just yet).
parent pom don't contain jar file
This is the reason why no bundle link is present on the official public maven repository https://mvnrepository.com
The maven dependency is not a jar, is a parent. So the extension is: .pom which is just a plain pom.xml
Parent dependencies don't contain compiled class like .jar.
In your specific case, there are another dependencies who contains jars:
https://repo1.maven.org/maven2/com/fasterxml/jackson/dataformat/jackson-dataformat-yaml/2.13.0/
https://repo1.maven.org/maven2/com/fasterxml/jackson/dataformat/jackson-dataformat-xml/2.13.0/
advice
Check what classes do you need on your ant project and search if exist a jar (with the classes you need) on https://mvnrepository.com
Another option is to get all the dependencies from pom :
https://repo1.maven.org/maven2/com/fasterxml/jackson/dataformat/jackson-dataformats-text/2.9.0/jackson-dataformats-text-2.9.0.pom and download them into your ant project. In theory is the same of add the parent pom in a maven project
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'm looking to pull all of the dependencies from each module of my maven project and stick them into a single tar.gz file using the maven-assembly-plugin.
I currently have a pom setup as a parent to all of the modules. My idea was to use the maven-dependency-plugin to copy all of the dependencies to a single folder in the parents directory however when i use
<configuration>
<outputDirectory>${project.build.directory}/lib</outputDirectory>
</configuration>
The dependencies are copied into the modules build directory. Is there any way to set this output directory to one inside the parent project?
You are going at it the wrong way.
Instead of creating this archive inside the parent POM, you should create another module which will be responsible for creating it. This new module will have dependencies on all the other modules.
To create the archive, you need to use the maven-assembly-plugin. I strongly suggest that you read Chapter 8. Maven Assemblies of the Maven book to get you started with using assemblies. Basically, an assembly is created with the help of an assembly descriptor. In your case, you will need to configure this descriptor to use the tar.gz format.
I need to create a dependent maven project.
The child one should be a jar, that would be called by the parent project which should be a war file.
The steps should be like this. When I build the war, it should automatically build the jar file and include it and build the war and show output of the child jar (suppose a simple print statement).
Note: Build should be done only once and that is for building the final war.
Need to edit the pom.xml accordingly.
I am new to maven,so a bit elaborate solution would be very helpful.
We have to build ontop of an application that we did not develop and we need to include some classes from the Jar's WEB-INF directory. How do we get maven to do this? The eclipse deployment directory includes this for local deploy but the built war looks different and does not include the files we place in the source.
You can use the dependency plugin unpack dependency option to unpack from a dependency and output it to a location you desired.
http://maven.apache.org/plugins/maven-dependency-plugin/unpack-dependencies-mojo.html
Or alternatively, you can use the maven assembly plugin's unpack describtor to achieve the same thing.
