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.

• If you are not working on Python, the simplest solution is to not build it, i.e. only build the module that you're interested in.
• If you do need to build Python, follow the instructions here: Set up IntelliJ for Python development

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.
