Issue Type: Bug Bug
Affects Versions: current
Assignee: Unassigned
Components: rvm
Created: 19/Jul/13 10:09 AM
Description:

I am using the rvm plugin to use the rvm environment on a slave instance of jenkins. I don't know when and why, but suddenly the config.xml of some jobs changes at the bottom to this:

<buildWrappers>
    <ruby-proxy-object>
      <ruby-object ruby-class="Jenkins::Plugin::Proxies::BuildWrapper" pluginid="rvm">
        <object ruby-class="RvmWrapper" pluginid="rvm">
          <launcher ruby-class="Jenkins::Launcher" pluginid="rvm">
            <native ruby-class="Java::Hudson::RemoteLauncher" pluginid="rvm"/>
          </launcher>
          <rvm__path pluginid="rvm" ruby-class="String">/usr/local/rvm/scripts/rvm</rvm__path>
          <impl ruby-class="NilClass" pluginid="rvm"/>
        </object>
        <pluginid pluginid="rvm" ruby-class="String">rvm</pluginid>
      </ruby-object>
    </ruby-proxy-object>
  </buildWrappers>

After a restart or reload of the config files jenkins won't load some jobs with the following error:

It work's when I change the config.xml part to...

<buildWrappers>
    <ruby-proxy-object>
      <ruby-object ruby-class="Jenkins::Plugin::Proxies::BuildWrapper" pluginid="rvm">
        <object ruby-class="RvmWrapper" pluginid="rvm">
          <impl ruby-class="NilClass" pluginid="rvm"/>
        </object>
        <pluginid pluginid="rvm" ruby-class="String">rvm</pluginid>
      </ruby-object>
    </ruby-proxy-object>
