I have checked the permissions on the config.xml and I am still receiving this error message. We are using Jenkins version 1.598. I recently rebooted it after a number of plugins were installed, so I am not certain if any are cause of the the issue.
I get this error right after restart. I have attempted to disable this and other plugins, but I cant determine whats wrong. hudson.util.HudsonFailedToLoad: org.jvnet.hudson.reactor.ReactorException: java.io.IOException: Unable to read /var/lib/jenkins/config.xml at hudson.WebAppMain$3.run(WebAppMain.java:237) Caused by: org.jvnet.hudson.reactor.ReactorException: java.io.IOException: Unable to read /var/lib/jenkins/config.xml at org.jvnet.hudson.reactor.Reactor.execute(Reactor.java:269) at jenkins.InitReactorRunner.run(InitReactorRunner.java:44) at jenkins.model.Jenkins.executeReactor(Jenkins.java:914) at jenkins.model.Jenkins.<init>(Jenkins.java:813) at hudson.model.Hudson.<init>(Hudson.java:83) at hudson.model.Hudson.<init>(Hudson.java:79) at hudson.WebAppMain$3.run(WebAppMain.java:225) Caused by: java.io.IOException: Unable to read /var/lib/jenkins/config.xml at hudson.XmlFile.unmarshal(XmlFile.java:167) at jenkins.model.Jenkins$16.run(Jenkins.java:2642) at org.jvnet.hudson.reactor.TaskGraphBuilder$TaskImpl.run( TaskGraphBuilder.java:169) at org.jvnet.hudson.reactor.Reactor.runTask(Reactor.java:282) at jenkins.model.Jenkins$7.runTask(Jenkins.java:903) at org.jvnet.hudson.reactor.Reactor$2.run(Reactor.java:210) at org.jvnet.hudson.reactor.Reactor$Node.run(Reactor.java:117) at java.util.concurrent.ThreadPoolExecutor.runWorker( ThreadPoolExecutor.java:1146) at java.util.concurrent.ThreadPoolExecutor$Worker.run( ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:701) Caused by: java.lang.NoClassDefFoundError: hudson/security/GlobalMatrixAuthorizationStrategy$DescriptorImpl at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:643) at jenkins.util.AntClassLoader.defineClassFromData(AntClassLoader.java:1138) at hudson.ClassicPluginStrategy$AntClassLoader2.defineClassFromData( ClassicPluginStrategy.java:784) at jenkins.util.AntClassLoader.getClassFromStream(AntClassLoader.java:1309) at jenkins.util.AntClassLoader.findClassInComponents( AntClassLoader.java:1365) at jenkins.util.AntClassLoader.findClass(AntClassLoader.java:1325) at jenkins.util.AntClassLoader.loadClass(AntClassLoader.java:1078) at java.lang.ClassLoader.loadClass(ClassLoader.java:268) at java.lang.Class.getDeclaredFields0(Native Method) at java.lang.Class.privateGetDeclaredFields(Class.java:2459) at java.lang.Class.getDeclaredFields(Class.java:1808) at com.thoughtworks.xstream.mapper.AnnotationMapper. processTypes(AnnotationMapper.java:216) at com.thoughtworks.xstream.mapper.AnnotationMapper.processAnnotations( AnnotationMapper.java:182) at com.thoughtworks.xstream.mapper.AnnotationMapper.defaultImplementationOf( AnnotationMapper.java:141) at com.thoughtworks.xstream.mapper.MapperWrapper.defaultImplementationOf( MapperWrapper.java:46) at hudson.util.xstream.MapperDelegate.defaultImplementationOf( MapperDelegate.java:59) at com.thoughtworks.xstream.mapper.MapperWrapper.defaultImplementationOf( MapperWrapper.java:46) at com.thoughtworks.xstream.core.TreeUnmarshaller.convertAnother( TreeUnmarshaller.java:54) at hudson.util.RobustReflectionConverter.unmarshalField( RobustReflectionConverter.java:349) at hudson.util.RobustReflectionConverter.doUnmarshal( RobustReflectionConverter.java:289) at hudson.util.RobustReflectionConverter.unmarshal( RobustReflectionConverter.java:228) at com.thoughtworks.xstream.core.TreeUnmarshaller.convert( TreeUnmarshaller.java:72) at com.thoughtworks.xstream.core.AbstractReferenceUnmarshaller.convert( AbstractReferenceUnmarshaller.java:65) at com.thoughtworks.xstream.core.TreeUnmarshaller.convertAnother( TreeUnmarshaller.java:66) at com.thoughtworks.xstream.core.TreeUnmarshaller.convertAnother( TreeUnmarshaller.java:50) at com.thoughtworks.xstream.core.TreeUnmarshaller.start( TreeUnmarshaller.java:134) at com.thoughtworks.xstream.core.AbstractTreeMarshallingStrategy.unmarshal( AbstractTreeMarshallingStrategy.java:32) at com.thoughtworks.xstream.XStream.unmarshal(XStream.java:1189) at hudson.util.XStream2.unmarshal(XStream2.java:113) at com.thoughtworks.xstream.XStream.unmarshal(XStream.java:1173) at hudson.XmlFile.unmarshal(XmlFile.java:163) ... 9 more Caused by: java.lang.ClassNotFoundException: hudson.security.GlobalMatrixAuthorizationStrategy$DescriptorImpl at jenkins.util.AntClassLoader.findClassInComponents( AntClassLoader.java:1375) at jenkins.util.AntClassLoader.findClass(AntClassLoader.java:1325) at jenkins.util.AntClassLoader.loadClass(AntClassLoader.java:1078) at java.lang.ClassLoader.loadClass(ClassLoader.java:268) ... 41 more -- You received this message because you are subscribed to the Google Groups "Jenkins Users" group.
