What steps will reproduce the problem? 1. On Windows, run Jenkins via java -jar jenkins.war. add builds to the mylyn builds view 2. install Jenkins as a Windows service and restart 3. hit "refresh" on the builds view For me, I get an error, and the builds do not refresh. Error is below. I do not get this error if jenkins is running from the command line. Here is the Eclipse error, followed below by some output in the jenkins error log. I'm not sure, honestly, if this is a Jenkins problem or a mylyn problem. I do know that if I hit localhost/api/xml in the browser, I get valid XML back -- Error Details -- Date: Tue May 31 16:04:48 EDT 2011 Message: Refresh of server 'Local Jenkins' failed Severity: Error Product: Eclipse 1.3.1.20100913-1228 (org.eclipse.epp.package.rcp.product) Plugin: org.eclipse.mylyn.builds.core Session Data: eclipse.buildId=M20100909-0800 java.version=1.6.0_24 java.vendor=Sun Microsystems Inc.

That looks like this issue: https://issues.jenkins-ci.org/browse/JENKINS-9387 . Since this is an error on the server side there is nothing we can do on the client end to fix it. If you are still seeing this with the latest Jenkins I would recommend to report this problem to the Jenkins project.
