I am not sure how to perform the "updating files e.g. pom.xml" step

Don't know if it's necessary to edit these files, or if plugins will load whatever jar is present, but with the Jenkins service stopped I edited:

1. JENKINS_HOME\plugins\dashboard-view\WEB-INF\licenses.xml

2. JENKINS_HOME\plugins\dashboard-view\META-INF\maven\org.jenkins-ci.plugins\dashboard-view\pom.xml

In both, search for where joda is mentioned, and change the version listed from "1.6" to "2.1". Then restart Jenkins service.

Thanks it worked:

1. remove JENKINS_HOME/plugins/dashboard-view/WEB-INF/lib/joda-time-1.6.jar
2. copy JENKINS_HOME/plugins/analysis-core/WEB-INF/lib/joda-time-2.1.jar to that folder
3. edit the files and change the version listed from "1.6" to "2.1":
   • JENKINS_HOME/plugins/dashboard-view/WEB-INF/licenses.xml
   • JENKINS_HOME/plugins/dashboard-view/META-INF/maven/org.jenkins-ci.plugins/dashboard-view/pom.xml
4. restart Jenkins

Hi Ulli Hafner, Have you checked whether we have to upgrade the dashboard-view? Using the workaround doesn't seem correct way to resolve the problem. Better, we should have an update of the plugin.

No, it works if I set the dependency to joda time 1.6 in analysis-core. The fix is already ready to be released...

Fixed in analysis-core 1.79.

Use the same library as dashboard-view to avoid classloading problems.

Hi, for me the same NoSuchMethodError is occurring again, and trend graphs are not displayed.

After downgrading Static Analysis plugin from 1.93 to 1.92, things work again.
