The pubsub one is concerning. Can you check whether the java-pubsub project references the variable?

downstream / javadoc-with-doclet (java-bigtable) is known to fail for now.

Looks like they are, we should remove the usage there.

Confirming whether the maven-compiler-plugin configuration at java-pubsub is really needed or not googleapis/java-pubsub#1761.

I merged googleapis/java-pubsub#1761 in pubsub. I just restarted "downstream / dependencies (11, java-pubsub) " job.

downstream / dependencies (11, java-pubsub) has passed now. Merging the PR.
