SNAPSHOT Jar files are not deployed when using maven-jar-plugin

[dlemmermann]

By default the maven-jar-plugin replaces all JAR file names with the word SNAPSHOT in them with a time stamp. A jar file called myjar-SNAPSHOT.jar will be renamed to myjar-20220409053011.jar (or something like that). This means that the class-path entry inside the generated manifest.mf file will list JAR files that are actually not present in the libs folder, hence they will not be copied to the jdeploy-bundle/libs directory as jdeploy uses the manifest information for the copying.

This can be prevented by specifying false in the configuration of the maven jar plugin.

I would propose to add this to the documentation and / or print out a warning.

I'm going to have to experiment a little bit to find the exact combination of parameters in the maven dependencies/maven jar plugin that results in this. I use those plugins and this behaviour doesn't seem to happen for me.

In any case, when it happens, it does make sense the jDeploy should print out a warning - and we should document this in a troubleshooting section.
