java.io.IOException: Unable to load ruby.RubyPlugin from gitlab-hook

    I try to set up GenyMotion for Jenkins and installed libgl1-mesa-dev package for GenyMotion. During installation this package I noticed that some packages were removed, for example, skype, teamviewer (it's very strange!) and maybe some jenkins files (it is my suggestion).After I installed this package and rebooted machine, I can not start Jenkins. Error log contains following messages: SEVERE: Failed Loading plugin gitlab-hook java.io.IOException: Unable to load ruby.RubyPlugin from gitlab-hook at hudson.ClassicPluginStrategy.load(ClassicPluginStrategy.java:355) at hudson.PluginManager$2$1$1.run(PluginManager.java:357) at org.jvnet.hudson.reactor.TaskGraphBuilder$TaskImpl.run(TaskGraphBuilder.java:169) at org.jvnet.hudson.reactor.Reactor.runTask(Reactor.java:282) at jenkins.model.Jenkins$7.runTask(Jenkins.java:905) 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:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:744) Caused by: java.lang.ClassNotFoundException: ruby.RubyPlugin 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:358) at hudson.ClassicPluginStrategy.load(ClassicPluginStrategy.java:346) ... 9 more Please help.
