I have a large project with a top-level pom building lower-level projects. When each of the lower-level projects had as their packaging target a "jar" file, everything worked as I would expect. I could do a "mvn install" in the top-level directory and maven would recurse into each sub-project (<module>) and do the appropriate thing. However, as I filled out my project, some of the sub-modules had other targets - war and wsr - and therefore not all projects had "jar" packaging. Now, when I do a "mvn install" from the top-level module, I get errors like this:
[ERROR] BUILD ERROR [INFO] ------------------------------------------------------------------------ [INFO] Internal error in the plugin manager executing goal 'org.apache.maven.plugins:maven-jar-plugin:2.1:jar': Unable to find the mojo 'org.apache.maven.plugins:maven-jar-plugin:2.1:jar' in the plugin 'org.apache.maven.plugins:maven-jar-plugin' This makes no sense to me, and I don't see what the non-jar projects (war and wsr) would have to do with this. In fact, I believe the sub-project that maven is trying to build at the time of this error is the first module - which *is* a jar package. Simply changing directories to this sub-project and doing a "mvn install" there works perfectly fine. In fact, I can go to each of the modules listed in the top-level pom and do a "mvn install" manually and they all work fine. Currently, that is my work-around. Any suggestions on why the above might be happening? (I'm using maven 2.0.4). -- Eric
