Below is a listing of common errors encountered while using IntelliJ. If you're having an issue that's not covered, please ask, and add your own notes.


A problem occurred starting process 'command 'virtualenv''

This can happen when you are setting up a new IntelliJ development environment when attempting to build or even clean for the first time:

FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':beam-sdks-python:setupVirtualenv'.
> A problem occurred starting process 'command 'virtualenv''

This indicates that virtualenv, used for Python development, is not currently available from IntelliJ.

Compilation failed with exit code 1; see the compiler error output for details.

This appears to be caused by poor parsing of the Gradle log by IntelliJ. In the log pane there is a button to toggle to the raw console.

IntelliJ can't load large files

(stack overflow post)

  • In IntelliJ 2016 and higher: go to Help → Edit Custom Properties → Paste the following inside the properties file:

    #---------------------------------------------------------------------
    # Maximum file size (kilobytes) IDE should provide code assistance for.
    # The larger file is the slower its editor works and higher overall system memory requirements are
    # if code assistance is enabled. Remove this property or set to very large number if you need
    # code assistance for any files available regardless their size.
    #---------------------------------------------------------------------
    idea.max.intellisense.filesize=2500
