After updating to the latest version of this plugin, there has been an issue with finding the clang scan build reports directory. The plugin is configured with:

Mark build as unstable when threshold is exceeded? == unset/false
Report folder == clangScanBuildReports (default value)

After a project, configured with the plugin has been build, the following exception is seen in the console

ERROR: Build step failed with exception
java.lang.NullPointerException
	at hudson.FilePath.isAbsolute(FilePath.java:271)
	at hudson.FilePath.resolvePathIfRelative(FilePath.java:256)

	at hudson.model.Executor.run(Executor.java:410)

After some investigation into the source code, the configuration was changed to set Mark build as unstable when threshold is exceeded?== set/true (with all other values left as default), this configuration produced a successful result. The difference in behaviour with the configuration change indicates the issue is with the publisher config.jelly and its constructor, however I am not well versed enough in this area to explain why or suggest a fix.

Hi,

I think the issue is related to the missing reportFolderName when the Job configuration is not saved after updating form < 1.7 to 1.7.

It works for me when configuring and saving the Job.

Before saving:

  <publishers>
    <jenkins.plugins.clangscanbuild.publisher.ClangScanBuildPublisher plugin="clang-scanbuild-plugin@1.6">
      <bugThreshold>15</bugThreshold>
      <clangexcludedpaths></clangexcludedpaths>
      <markBuildUnstableWhenThresholdIsExceeded>true</markBuildUnstableWhenThresholdIsExceeded>
    </jenkins.plugins.clangscanbuild.publisher.ClangScanBuildPublisher>
  </publishers>

After saving:

  <publishers>
    <jenkins.plugins.clangscanbuild.publisher.ClangScanBuildPublisher plugin="clang-scanbuild-plugin@1.7">
      <bugThreshold>15</bugThreshold>
      <clangexcludedpaths></clangexcludedpaths>
      <reportFolderName>clangScanBuildReports</reportFolderName>
      <markBuildUnstableWhenThresholdIsExceeded>true</markBuildUnstableWhenThresholdIsExceeded>
    </jenkins.plugins.clangscanbuild.publisher.ClangScanBuildPublisher>
  </publishers>

Solution:
Probably there needs to be an upgrade path or backward compatible path in the Clang Scanbuild Plugin.
