Intellij 12 - Can't Reimport Module

Question

So I ran into a strange problem today. I was having some issues with one of my modules in IntelliJ so I decided I should try blowing it out and rebuilding it from a fresh checko

Answer 1

This was resolved by going to GRADLE Tab on the project and removing other modules that needs to be reimported.

Answer 2

I had the same problem with a Gradle module. For me the fix was simply to delete this entry from the .idea/workspace.xml

  <component name="ExternalProjectsManager">
    <system id="GRADLE">
      <state>
        <task path="$PROJECT_DIR$/Locations">
          <activation />
        </task>
        <projects_view>
          <tree_state>
            <expand>
              <path>
                <item name="" type="6a2764b6:ExternalProjectsStructure$RootNode" />
                <item name="locations" type="f1a62948:ProjectNode" />
              </path>
              <path>
                <item name="" type="6a2764b6:ExternalProjectsStructure$RootNode" />
                <item name="locations" type="f1a62948:ProjectNode" />
                <item name="Run Configurations" type="7b0102dc:RunConfigurationsNode" />
              </path>
            </expand>
            <select />
          </tree_state>
        </projects_view>
      </state>
    </system>
  </component>

If you are using a maven structure, it could be that you ignore the poms after unloading modules. Check this at:

File | Settings | Build, Execution, Deployment | Build Tools | Maven | Ignored Files

Uncheck your modules and try again.

(If you have many files listed there, just deselect all via Ctrl + A, Space)
