jenkins.util.MarkFindingOutputStream class is missing : Maven build not working in slave mode

[Yoann Dubreuil]

Maven build doesn't work in slave mode : the Maven build plugin requires the class jenkins.util.MarkFindingOutputStream to work but this class is not in the jenkins WAR built by Ubuntu. This class is present in the official build of Jenkins LTS 1.466.1

When i try to build a Maven project in a slave, i see this stacktrace :

Modules changed, recalculating dependency graph

I dont understand why the MarkFindingOutputStream class in not present because the source file is in the source package in this folder : core/src/main/groovy/jenkins/util/MarkFindingOutputStream.java. The other source file present in this folder is ServerTcpPort and is correctly compiled and included in the WAR file of Jenkins.

Anyway, theses two files are in the wrong folder (groovy sources). Upstream fixed this : https://github.com/jenkinsci/jenkins/commit/2338b6682146e912c9a4d3769eff4864e487c427.

I think that the best thing to do is to move theses files in the right source folder.

Hope this helps,

Yoann.

Thanks for the bug report Yoann

I'd noticed this issue and had picked up on the ServerTcpPort.java file but had missed the other one.
