I have a Maven assembly script that copies resources to build our app. I need to copy some war files from separate, external projects into a /webapps directory in the output. Can't seem to find the magic commands to do it.
I tried adding a dependencySet to the assembly with <include com.mygroup:mywarfile>. This works if I add 'mywarfile' as a war dependency in the project with a scope of compile or runtime. Unfortunately, my project produces a war, and the maven-war-plugin includes the external mywarfile as an overlay, which I don't want.
If I set the scope of the external war dependency to provided or test, the assembly fails with the warning:
[WARNING] The following patterns were never triggered in this artifact inclusion filter:
'com.mygroup:mywarfile'
All I want to do is have the assembly copy an artifact from my local repo to the assembly output. How to do it without messing up other parts of the project?
The maven-assembly-plugin is not intended for copying. The better way to copy dependencies is the maven-dependency-plugin which can copy dependencies etc. If you a talking about deployment into Tomcat etc. than you should take a deeper look into carg2-maven-plugin or the tomcat-maven-plugin which seemed to be more appropriate for that task.
I haven't tried this, but you could try using the exclude feature of overlay configuration of maven war plugin to exclude contents of the dependant war file from being included in your war project. Modified snippet from the Overlay documentation,
...

<plugins>
<plugin>
