Builds stopped working - Hudson.plugins.view.dashboard.DashboardPortlet not present

[Sampath....@vce.com]

The VM where Jenkins CI is running, was reaching to a point of disk space being full. Our Admin decided to increase the disk space. After that the builds stopped working. Both “Build Now” link as well as scheduled builds do not work anymore. Here is the exception details in the log –

 

Failed to load hudson.plugins.cobertura.dashboard.CoverageTablePortlet$DescriptorImpl

java.lang.LinkageError: Failed to resolve class hudson.plugins.cobertura.dashboard.CoverageTablePortlet$DescriptorImpl

 

Caused by java.lang.TypeNotPresentException: Type hudson.plugins.view.dashboard.DashboardPortlet not present

Caused by java.lang.ClassNotFoundException: hudson.plugins.view.dashboard.DashboardPortlet

 

Looking at the link https://issues.jenkins-ci.org/browse/JENKINS-11398, I installed Dashboard plugin but it still does not help. The environment stopped working.

 

When I go to “smart Jenkins” page, everything shows up in “Blocked” state.

 

Never realized that adding extra disk space would lead to this situation.

 

Thanks for any help.
