Are "Referenced Libraries" shared amongst projects in workspace? [message #1095789] Tue, 27 August 2013 10:25 Go to next message

I have a Maven project with 4+ submodules. Each submodules have their respective dependencies as seen in the "Referenced Libraries" section. For JARs that are common to all submodule, are they duplicated for each submodule in the workspace or is it just a pointer to a single JAR?

If they are individual, is it possible to create one big referenced library pool so that the JARs don't get replicated in each submodule?

Vanilla Java projects support this in a couple of ways. You can setup a project reference on the Build Path dialog. The project hosting the jars has to have them checked on the Order and Export tab. This exports the jar files to dependent projects. On the Projects tab of the dependent projects, check the project hosting the jar. If you have a number of common jars, you can create a Java project with no source, just the jars defined on the Libraries tab. Then export them on the Order and Export tab. Select the library project as the Projects tab of dependent projects.

Note that I said vanilla Java project. I don't know if these features are compatible with the Maven plugin. Maven is intended to manage jar file dependencies for you so my guess is that it might work differently. You should probably consult the Maven(M2E) news group for guidance with maven projects.
