At work, this file is no more than this:
```XML
<?xml version="1.0" encoding="UTF-8"?>
<project version="4">
  <component name="EntryPointsManager">
    <entry_points version="2.0" />
  </component>
  <component name="ProjectRootManager" version="2" languageLevel="JDK_1_6" assert-keyword="true" jdk-15="true" project-jdk-name="JDK" project-jdk-type="JavaSDK">
    <output url="file://$PROJECT_DIR$/build/classes" />
  </component>
</project>
```

Could it be that this one includes a lot of plugins that aren't needed for the project?
