Fix ci: there was an issue during publishing (#282)

Reason: Task ':java-cfenv-all:generateMetadataFileForShadowPublication' uses this output of task ':java-cfenv-all:jar' without declaring an explicit or implicit dependency. This can lead to incorrect results being produced, depending on what order the tasks are executed.
