I fixed this.
Problem was that gradle tried to execute inside checkout/ subdirectory instead
of workspace root.
Reason was that the job wax copied from Lucene, but the enwiki parallel
checkout using subversion was removed.
Lucene night jobs checkout two repositories into 2 folders next to each
https://ci-builds.apache.org/job/Solr/job/Solr-NightlyTests-main/38/console
looks like it is failing because something is wrong with either the
checkout or the connection to the jenkins workers or agents. I don't
really know enough about Jenkins to troubleshoot this, but bringing it
up in case some
