FileNotFoundException when using comment file path

I’m trying to use comment file path to add comment to PRs with some analysis results read from a text file that has previously been created during build phase. According to build log, reading comment file seems to be the last build step that was executed, which means the file should already exist at that point, but I still get FileNotFoundException. The path I use is ${WORKSPACE}/path/to/comment/file and I double check to make sure it exists.

The job was executed on a remote slave machine, which is connected by Jenkins master via SSH. I suspect the plugin was trying to read a file on Jenkins master and thus couldn’t find the file, whose path is meant for the slave machine, but I could be wrong.

Some context:

• Jenkins version: 1.651.1
• Gihub plugin version: 1.18.1
• Github API plugin version: 1.72.1
• Github authentication plugin version: 0.22.3
• GHPRB plugin version: 1.31.2

Full stack trace:

Ok. I investigated a little bit into this problem. It happens if the build starts on a slave, on a master node everything works fine.

If the Jenkinsfile is in subdirectory, specify the sub directory (ex: test/Portal/Jenkinsfile) path till the Jenkinsfile and then uncheck the Lightweight checkout.

Now build the project.
