Attempt to (de-)serialize anonymous class hudson.maven.reporters.MavenArtifactArchiver and hudson.maven.reporters.MavenFingerprinter

[g***@ge.com]

Hello,



I was on Jenkins 1.6.x I’ve upgraded and fresh install of Jenkins 2.136.



Since the upgrade I continuously get these warnings. I’m not sure what this
is saying. Any help would be greatly appreciated. Thanks!



I looked at the doc, but, don’t know what to do with it.



*[WARNING] Attempt to (de-)serialize anonymous class hudson.maven.reporters.MavenArtifactArchiver$2; see: https://jenkins.io/redirect/serialization-of-anonymous-classes/ <https://jenkins.io/redirect/serialization-of-anonymous-classes/>*

*[WARNING] Attempt to (de-)serialize anonymous class hudson.maven.reporters.MavenFingerprinter$1; see: https://jenkins.io/redirect/serialization-of-anonymous-classes/ <https://jenkins.io/redirect/serialization-of-anonymous-classes/>*





Thanks!

Hi Gary,

As the linked page explains, anonymous classes can cause various problems when serializing objects in Jenkins, so these messages are printed as a warning so we can identify potential issues. I think these are the anonymous classes in question: MavenArtifactArchiver$2 <https://github.com/jenkinsci/maven-plugin/blob/7ac83fa85fda0c4d1d02663059644f0655823879/src/main/java/hudson/maven/reporters/MavenArtifactArchiver.java#L131>, MavenFingerprinter$1 <https://github.com/jenkinsci/maven-plugin/blob/7ac83fa85fda0c4d1d02663059644f0655823879/src/main/java/hudson/maven/reporters/MavenFingerprinter.java#L112>. It looks like they are only used for remoting, so a PR to convert them to named classes would be welcome.

It looks like someone reported the issue on the bug tracker: JENKINS-53481 <https://issues.jenkins-ci.org/browse/JENKINS-53481> and a PR was opened to fix it: https://github.com/jenkinsci/maven-plugin/pull/120 <https://github.com/jenkinsci/maven-plugin/pull/120>, but I do not know if there are any active maintainers who can merge and release the fix.

A PR is a Pull Request on GitHub <https://help.github.com/articles/about-pull-requests/>. Here is the offending plugin’s source code: https://github.com/jenkinsci/maven-plugin <https://github.com/jenkinsci/maven-plugin>. You could instead open an issue on Jira if you are not comfortable with Java development, but I don’t know how much time the Maven Plugin maintainers have to work on the plugin so it may be a while before anyone fixes it.
