ivy:report ant task intermittently "cannot compile stylesheet"

    Details

    • Type: Bug
    • Status: Resolved
    • Priority: Major
    • Resolution: Fixed
    • Affects Version/s: 2.2.0
    • Fix Version/s: 2.3.0-RC1
    • Component/s: None
    • Labels:
      None
    • Environment:

      ivy-2.2.jar, Sun jdk 1.5 and 1.6 for compiling, Jenkins 1.436 as CI server, ant 1.8.2, Linux, Jenkins ivy plugin 1.20

      Description

      Setup:

      o Using ivy-2.2.jar.

      o Compiling with Sun jdk versions 1.5 or 1.6 (project dependent) on a Linux box.

      o Running ant 1.8.2 via a wrapper script inside Jenkins 1.436 with 5 or so
      executors. That is, each build invokes a simple custom wrapper-script around
      Ant that puts some custom tasks and ivy-2.2 on the build classpath.

      o Jenkins Ivy plugin version is version 1.20 which uses ivy 2.2.0 internally.

      Problem:

      We hit this error perhaps 8 % of the builds when there are several
      parallel builds happening:

      javax.xml.transform.TransformerConfigurationException: Could not compile stylesheet
      at com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl.newTemplates(TransformerFactoryImpl.java:828)
      at com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl.newTransformer(TransformerFactoryImpl.java:617)
      at org.apache.ivy.ant.IvyReport.genStyled(IvyReport.java:322)
      at org.apache.ivy.ant.IvyReport.genreport(IvyReport.java:248)
      at org.apache.ivy.ant.IvyReport.doExecute(IvyReport.java:211)
      at org.apache.ivy.ant.IvyTask.execute(IvyTask.java:277)
      :
      :

      The build always runs fine for a single job when invoked from the
      command line, and 99.9% of the time runs fine when the Jenkins job is
      requeued. But when it happens during parallel builds, the error
      message is always the same and always in exactly the same spot in
      IvyReport.java.

      The relevant ant task is this (we are behind a firewall so retrieves
      never go out to the internet, all resolvers are FileSystem resolvers,
      which explains some of the attribute values):

      <macrodef name="resolve-dependencies">
      <attribute name="ivyconfig"/>
      <sequential>
      <ivy:resolve
      conf="@

      {ivyconfig}"
      log="${option.ivy.log}"
      resolveMode="dynamic"
      showprogress="false"
      checkIfChanged="false"
      />

      <ivy:retrieve
      conf="@{ivyconfig}

      "
      log="${option.ivy.log}"
      pattern="${ivy.lib.dir}/@

      {ivyconfig}/[artifact](-[revision]).[ext]"
      symlink="true"
      sync="true"
      />

      <ivy:report <---------------- INTERMITTENT FAILURE DURING THIS TASK
      conf="@{ivyconfig}

      "
      dot="${option.ivyreport.dot}" <--- false on Jenkins, settable for indiv developer
      graph="${option.ivyreport.graphml}" <--- false on Jenkins, settable for indiv developer
      outputpattern="dependencies-[conf].[ext]"
      todir="${dir.build}/report"
      />
      </sequential>
      </macrodef>

      As you can see from the code, we are not using our own stylesheet, but
      the one in the ivy distribution.

      The code in IvyReport.java looks ok to me but I am not a TRaX user and
      certainly no expert on it so it is not clear to me why occasionally we
      get this "cannot compile stylesheet" error. And we only get it when
      many builds are happening in parallel, never for one-build-at-a-time,
      which makes me wonder if there is some issue with grabbing resources
      from inside a jar, something I do not do myself.
