[BUG] IntelliJ: IllegalArgumentException when Opening Non-Python Projects

[cspurk]

Opening non-Python projects in IntelliJ with the plugin enabled yields an “IDE Internal Error” like this one:

java.lang.IllegalArgumentException: PythonSDK is not defined or robot version is not valid for project FOOBAR

A comment on #400 recommends configuring a Python interpreter, however, that doesn’t seem to make sense for non-Python projects.

Even if a Python SDK should be needed for RobotCode, it should not be mandatory for IDE projects which don’t use the Robot Framework.

• RobotCode Version: 1.0.3
• OS: Linux
• Python Version: N/A
• RobotFramework Version: N/A

Which IDE are you using — PyCharm or IntelliJ? And what exactly do you mean by “non‑Python projects”?
The language server should normally only start when it detects Robot Framework files or a pyproject.toml/robot.toml.

The exception you’re seeing is due to the project’s early development stage; it will be handled more gracefully in a future release.

Thanks for your prompt response! I use IntelliJ. By “non-Python projects” I mean IDE projects which don’t use Python in any way; they might be using Java, Scala, etc. The error definitely occurs also for projects without any pyproject.toml/robot.toml files.

Maybe I should note that I often have multiple projects opened, some of which may contain pyproject.toml files and/or use the Robot Framework. However, the error also occurs when I only open projects that don’t use any of this (e.g., classical Java projects without Robot Framework usage).
