…es jar maven-source-plugin 3.3.x fails with "We have duplicated artifacts attached" when the attach-sources execution runs in a build that also invokes source:jar on the command line (MSOURCES-143), which is how the Jenkins deploy job runs. Pin to 3.2.1, matching fess-parent. See https://issues.apache.org/jira/browse/MSOURCES-143

Summary
The Jenkins deploy job started failing with
We have duplicated artifacts attachedafter #20/#21 added anattach-sourcesexecution (maven-source-plugin 3.3.1) to thereleaseprofile. The Jenkins job also invokessource:jaron the command line, so the sources jar gets attached twice in the same build. Since 3.3.0, maven-source-plugin fails on duplicate attachment instead of silently overwriting (MSOURCES-143).Changes Made
maven-source-pluginto 3.2.1 in thereleaseprofile, with a comment pointing to MSOURCES-143fess-parentTesting
mvn clean source:jar package -Preleaseon master (fails with the same error)corelib-0.7.2-SNAPSHOT-sources.jaris built and attached correctlyAdditional Notes
attach-sourcesexecution from the POM or droppingsource:jarfrom the Jenkins job goals; pinning 3.2.1 keeps the POM self-contained for releases and is consistent with other CodeLibs repositories.
