we are using warnings-ng plugin on jenkins to visualize the result of IntelliJ-Idea-Inspections. Our observation:

• jobs, which reported inspection-results with an older version of the plugin, still allow sorting for module/package/file/categories/issues.
• jobs, which report inspection-results with version 10.0.2 of the plugin, don't allow sorting for module anymore - only for package/file/categories/issues.
• the provided information (input for the plugin as xml-file) is identical.
   

Problem imho is in the file idea-outstanding-issues.xml, 

old (with ability to sort for modules):

<analysisReport plugin="analysis-model-api@10.21.0">
...
<subReports>
    <analysisReport>
    ...
    <elements class="linked-hash-set">
        <issue>
        ...
{color:#de350b}          <moduleName>base-ls</moduleName>{color}

          
new (without ability for sort for modules):

<analysisReport plugin="analysis-model-api@11.0.0">
...
<subReports>
    <analysisReport>
    ...
    <elements class="linked-hash-set">
        <issue>
        ...
{color:#de350b}          <moduleName>-</moduleName>{color}

the module probably gets parsed from the provided xml-files for each entry:

<problems>
<problem>
  ...
  <module>KIXCustomer.base-ls.main</module>
  ...
</problem>

assumptions:

• as the module information is '-' for all entries, sorting for modules is not a valid option, therefore there is no button.
• problem is in parsing module-information from input file.
   
  we would be glad, if sorting for modules is possible again.
