Intellij 12 - Can't Reimport Module

If this is a Gradle module, please check the .idea project folder there is a gradle.xml

  <GradleProjectSettings>
    <option name="distributionType" value="DEFAULT_WRAPPED" />
    <option name="externalProjectPath" value="$PROJECT_DIR$/xxx" />
    <option name="gradleHome" value="/opt/gradle/gradle-2.13" />
    ......
  </GradleProjectSettings>

you should remove this entry and try to reimport your module

I am using Intellij Idea 2016.1.3, Mac OSX El Capitan 10.11.5

I also had this problem with an SBT module. You can remove the offending module by going to the SBT tool window, right clicking on the module and selecting "Detach external project".

Ah ha! I think I found the answer.

In my .idea project folder there is a misc.xml. In this file I found

<option name="ignoredFiles">
    <set>
        <option value="$PROJECT_DIR$/../Projects/.../module/pom.xml />
    </set>
</option>

I removed that and also cleaned up some duplicate entries from other areas that pertained to my module and I was able to import again.

IntelliJ is pacified for at least another day!
