I modified one build,
https://ci-builds.apache.org/job/Solr/job/Solr-Maven-Snapshots-main/ to
have an additional shell execution step with that snippet, which performs

wrapper all around it.  It ran successfully this morning.  I'm not sure why
Docker is involved for what looks like a simple file removal; might you
explain?
