Issue

I am seeing the following error in my logs when attempting to run a job or on startup:

SEVERE  hudson.LocalPluginManager#loadBundledPlugins: Failed to extract the bundled plugin scm-api.hpi
java.io.IOException: File '/nobackup/jenkins/plugins/scm-api.jpi' cannot be written to

Environment

• CloudBees Core on modern cloud platforms - Managed Master
• CloudBees Core on modern cloud platforms - Operations Center
• CloudBees Core on traditional platforms - Client Master
• CloudBees Core on traditional platforms - Operations Center
• CloudBees Jenkins Enterprise - Managed Master

Resolution

This issue typically happens when an hpi or jpi plugin file is copied into the $JENKINS_HOME/plugins directory with incorrect permissions. To resolve this, modify the file ownership permissions of the file(s) to match the username under which Jenkins is running.
