mvn deploy fails with fatal error on typepal

This is an example failed action: https://github.com/usethesource/typepal/runs/4105740347?check_suite_focus=true

It is unclear to me what is going wrong. The root error message does not make sense to me:

compiling: basedir /home/runner/work/typepal/typepal/target/generated-sources/annotations does not exist -> [Help 1]

• The double typepal/typepal looks weird, but that does not have to be the problem
• neither generated-sources, nor annotations are relevant in this project
• yet somehow we are looking for annotations in generated-sources

pls help?

This is the entire log:

Start with the linked GitHub Actions run and the Maven command shown in the log, then inspect how maven-full-artifacts-action invokes Maven for typepal. Determine why the compile step expects target/generated-sources/annotations and verify the fix by rerunning the deployment workflow without the fatal error.
