task-unzip submodule: Maven goal fails

[duracotton]

A mvn clean install (or package) of the "task-unzip" submodule fails with the following error on several machines/setups:

Maven is actually downloading the Apache commons-compress-1.19.jar to the local Maven repository and it is also being copied to the project's lib folder. So that is working and the dependency is actually present on the filesystem. However, Maven can not find this dependency.

Importing the submodule in Eclipse shows the same. Eclipse isn't able to auto-complete an "import" statement to "org.apache.commons.*":

The Properties > Build path of that submodule doesn't show any Maven dependencies (actually the "Maven Dependencies" list wasn't even there! I had to edit the .classpath file for that):

I did not come up with any solution so far - do you have any ideas?

Thank you

Found the issues:

15 increases the Apache commons-compress library to 1.19, but this change has not been adapted to the build.properties and MANIFEST.MF

Fixed. You need to once run mvn package on the console
