How to fix IntelliJ cannot resolve symbol
Thursday 08, October 2015   |   Post link
Ever since copying a Gradle project from one computer to another I have been getting 'cannot resolve symbol String' and similar messages in IntelliJ. Listed below are steps which *may* fix the problem:
  • Invalidate and refresh the IntelliJ's caches
    File Menu -> Invalidate Caches / Restart
  • Project SDK selection
    Check project settings from File Menu -> Project Structure
    Ensure an SDK is selected for the Project SDK. If is selected, click the 'New' button, select JDK and then select the correct path to the JDK e.g. /opt/java/jdk1.8 or c:\Java\Jdk1.8

  • Corrupt JDK
    There may be a problem with your JDK installation, re-install JDK
  • Re-import the project
    Close the project if it is open in IntelliJ
    Delete the .idea folder in the project source code folder.
    Start IntelliJ and Import the project.
