Getting at least some benefit from pipeline caching when over 1GB limit

[Janek Bogucki]

I have bb pipeline caching enabled. At the build end I see,

Build teardown1m 31s

Cache "maven": Compressing

Cache "maven": Compressed

Cache "maven": Compressed size is larger than upload limit (1 GB more than the 1 GB limit). Skipping cache upload.

Is there anyway I can use the 1 GB to provide some benefit. If I could blacklist certain jars that would help.

Could I run a script at the run of the build to delete part of ~/.m2/repository?

[Janek Bogucki]

I added this script to the pipelines configuration. At the end of the build with deletes the artifacts generated by the build which reduced the M2 repo directory to < 1GB.

#!/usr/bin/env bash

# mvn -B help:evaluate -Dexpression=settings.localRepository
du -sh /root/.m2/repository/*
echo
du -sh /root/.m2/repository/com/*
echo
du -sh /root/.m2/repository/org/*
echo
echo "Total size:"
du -sh /root/.m2/repository/

# 1.5G	/root/.m2/repository/com/inferess
echo "Deleting from /root/.m2/repository/com/inferess"
rm -rf /root/.m2/repository/com/inferess
echo
echo "Total size:"
du -sh /root/.m2/repository/

## 130M	/root/.m2/repository/org/apache
#echo "Deleting from /root/.m2/repository/org/apache"
#rm -rf /root/.m2/repository/org/apache
#echo
#echo "Total size:"
#du -sh /root/.m2/repository/

The commented out code allowed me to identify candidates for deletion.

It would be useful to have an option to Maven caching to list paths under the repo to exclude from the cached repo. I will never need to cache artifacts the build will create.
