Verify stage caches an empty directory for the main JAR #449
Description
Affected version
1.2.2
Bug description
When running mvn clean compile and mvn clean verify in that order, the cached main artifact (the JAR in the build-cache/v1.1) is a directory instead of a ZIP/JAR file.

Checking JARs in target dir:

target/maven-build-cache-test-1.0-SNAPSHOT-sources.jar: Zip archive data, at least v1.0 to extract, compression method=store
This is likely related to #394.
To reproduce
For convenience I have created a reproducer Project here: https://github.com/mensinda/maven-build-cache-test/tree/verify-fail
Please only use the verify-fail branch!
Then just run the run.sh shell script. This will automatically execute the relevant maven commands. It will also ensure that a local m2 Repository + build cache is used for better reproducibility.
