Motivation

I am looking into why builds are not reproducible and I was investigating this project v1.0.0. I was not able to reproduce the artifact paimon-format-1.0.0-sources.jar because it seems it has one file, org/apache/parquet/filter2/compat/, less than the reference version on Maven central. Maybe I am missing something from build command that the scripts are using as Hervė suggests?
The mvn command that the scripts run:

mvn -Papache-release clean package -DskipTests -Dmaven.javadoc.skip -Dgpg.skip -Dexec.skip \
    -V -e org.apache.maven.plugins:maven-artifact-plugin:3.6.0:compare org.apache.maven.plugins:maven-artifact-plugin:3.6.0:describe-build-output -Dbuildinfo.reproducible -Dcompare.fail=false 

First line is specific to this project and the second line is specific to verifying the artifacts generated.

Solution

Anything else?

This PR is related to #3719 and all preceding PRs related to reproducibility. I hope this is the right template to ask for such kind of help :)

This is possible if git checkout deletes all files in a certain directory. git does not track directory but they are on the filesystem and hence they are compressed into the archive. I am assuming that during the release the empty directory org/apache/parquet/filter2/compat/ existed on filesystem.
