I'm attempting to update from 2.263.1 to 2.375.1 (huge gap I know), and I'm getting this on the Jenkins page. It just shows 2 Jenkins butler pics, a large black circle, and a large blue circle with a question mark in the middle.
I've even renamed my $JENKINS_HOME/plugins and $JENKINS_HOME/plugins.txt files in case there are incompatible plugins which I expect from a huge version gap. Any clues? java.lang.NoClassDefFoundError: org/jruby/javasupport/proxy/InternalJavaProxy at org.jenkinsci.jruby.JRubyMapper.serializedClass(JRubyMapper.java:20) at hudson.util.xstream.MapperDelegate.serializedClass(MapperDelegate.java:41) at com.thoughtworks.xstream.mapper.MapperWrapper.serializedClass(MapperWrapper.java:121) at com.thoughtworks.xstream.core.TreeMarshaller.start(TreeMarshaller.java:82) at com.thoughtworks.xstream.core.AbstractTreeMarshallingStrategy.marshal(AbstractTreeMarshallingStrategy.java:37) at com.thoughtworks.xstream.XStream.marshal(XStream.java:1266) at com.thoughtworks.xstream.XStream.marshal(XStream.java:1255) at com.thoughtworks.xstream.XStream.toXML(XStream.java:1228) at hudson.XmlFile.write(XmlFile.java:213) at jenkins.model.Jenkins.save(Jenkins.java:3547) at jenkins.model.Jenkins.<init>(Jenkins.java:1007) at hudson.model.Hudson.<init>(Hudson.java:86) at hudson.model.Hudson.<init>(Hudson.java:82) at hudson.WebAppMain$3.run(WebAppMain.java:247) Caused: hudson.util.HudsonFailedToLoad at hudson.WebAppMain$3.run(WebAppMain.java:261) Thanks, Chris -- You received this message because you are subscribed to the Google Groups "Jenkins Users" group.
