Jenkins: failures due to an extra "%402" character in the location address

Question

My runs are failing, I think due to existence of this suspicious character "%402" in the location addresses. When I check the folder name via terminal this folder name does not exist, while it appears in the Jenkins logs. I wonder anyone has similar experiences.

Here is a snippet from the error log:

Results :

Answer 1

Edit : Post totally rewrited with the solution.

When you use the "ws" directive in your Jenkinsfile, Jenkins creates multiple workspace folder to execute concurrent build :

• jobName_branch-generated_key@2
• jobName_branch-generated_key@2@tmp
• jobName_branch-generated_key@script

You can get more informations on this thread.

The hexadecimal code for the special character "@" is "%40", so the extra character that you see is in fact this "@2" suffix with the encoded "@".

I've analyzed the source code of Jenkins and see that you can override the default character "@" used to build the suffix.

To solve this problem you just have to add the system property "-Dhudson.slaves.WorkspaceList=${new_character}" when you launch your Jenkins Server.

Here is the line of code that load the property from system.

I can see Perforce (P4 Plugin) doesnt like it when there is this @

I am using Amazon Linux so this is what I did to get it working

sudo nano /etc/sysconfig/jenkins
# Added This line
JENKINS_JAVA_OPTIONS="-Djava.awt.headless=true -Duser.timezone=America/Los_Angeles -Dhudson.slaves.WorkspaceList='_'"

Answer 3

I ran into the same problem, but didn't have access to change the Jenkins config. I was able to get it working by manually defining a custom workspace for each sub-stage.

stage('stage1'){
  agent {
    node {
      label 'master'
      customWorkspace "${BUILD_TAG}-id"
    }
  }
}
