E.g. http://jenkins.ovirt.org/job/ovirt_engine_sanity_compile_checkstyle_gerri...: consoleTriggered by Gerrit: http://gerrit.ovirt.org/18854 Building remotely on centos64-vm01 in workspace /home/jenkins/workspace/ovirt_engine_sanity_compile_checkstyle_gerrit Checkout:ovirt_engine_sanity_compile_checkstyle_gerrit / /home/jenkins/workspace/ovirt_engine_sanity_compile_checkstyle_gerrit - hudson.remoting.Channel@381f2c7e:centos64-vm01 Using strategy: Gerrit Trigger Last Built Revision: Revision 1b81a483250b4c0969b6bfac04dd8e8330a97d11 (master) Cloning the remote Git repository Cloning repository git://gerrit.ovirt.org/ovirt-engine Error trying to determine the git version: Error performing command: /usr/lib/jvm/jre-1.6.0-openjdk.x86_64/ --version Assuming 1.6 ERROR: Error cloning remote repo 'origin' : Could not clone git://gerrit.ovirt.org/ovirt-engine hudson.plugins.git.GitException: Could not clone git://gerrit.ovirt.org/ovirt-engine at org.jenkinsci.plugins.gitclient.CliGitAPIImpl$1.execute(CliGitAPIImpl.java:226) at org.jenkinsci.plugins.gitclient.AbstractGitAPIImpl.clone(AbstractGitAPIImpl.java:57) at org.jenkinsci.plugins.gitclient.CliGitAPIImpl.clone(CliGitAPIImpl.java:33) at hudson.plugins.git.GitSCM$2.invoke(GitSCM.java:1006) at hudson.plugins.git.GitSCM$2.invoke(GitSCM.java:942) at hudson.FilePath$FileCallableWrapper.call(FilePath.java:2387) at hudson.remoting.UserRequest.perform(UserRequest.java:118) at hudson.remoting.UserRequest.perform(UserRequest.java:48) at hudson.remoting.Request$2.run(Request.java:326) at hudson.remoting.InterceptingExecutorService$1.call(InterceptingExecutorService.java:72) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:334) at java.util.concurrent.FutureTask.run(FutureTask.java:166) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:724) Caused by: hudson.plugins.git.GitException: Error performing command: /usr/lib/jvm/jre-1.6.0-openjdk.x86_64/ clone -o origin git://gerrit.ovirt.org/ovirt-engine /home/jenkins/workspace/ovirt_engine_sanity_compile_checkstyle_gerrit/ovirt-engine at org.jenkinsci.plugins.gitclient.CliGitAPIImpl.launchCommandIn(CliGitAPIImpl.java:797) at org.jenkinsci.plugins.gitclient.CliGitAPIImpl.access$100(CliGitAPIImpl.java:33) at org.jenkinsci.plugins.gitclient.CliGitAPIImpl$1.execute(CliGitAPIImpl.java:224) ... 14 more Caused by: java.io.IOException: Cannot run program "/usr/lib/jvm/jre-1.6.0-openjdk.x86_64/": error=13, Permission denied at java.lang.ProcessBuilder.start(ProcessBuilder.java:1041) at hudson.Proc$LocalProc.<init>(Proc.java:244) at hudson.Proc$LocalProc.<init>(Proc.java:216) at hudson.Launcher$LocalLauncher.launch(Launcher.java:763) at hudson.Launcher$ProcStarter.start(Launcher.java:353) at hudson.Launcher$ProcStarter.join(Launcher.java:360) at org.jenkinsci.plugins.gitclient.CliGitAPIImpl.launchCommandIn(CliGitAPIImpl.java:786) ... 16 more Caused by: java.io.IOException: error=13, Permission denied at java.lang.UNIXProcess.forkAndExec(Native Method) at java.lang.UNIXProcess.<init>(UNIXProcess.java:135) at java.lang.ProcessImpl.start(ProcessImpl.java:130) at java.lang.ProcessBuilder.start(ProcessBuilder.java:1022) ... 22 more Trying next repository ERROR: Could not clone repository Can you please take care of this?
