Download documentation failed

Hi, I’m working on an Android Project, whenever I hover on a function or something else I should see the documentation but I see “Download documentation” instead. If I try to run it, I get the error:

Task 'ijDownloadSourcesb164191b-ff9' not found in project ':app'.

* Try:
> Run gradle tasks to get a list of available tasks.
> For more on name expansion, please refer to in the Gradle documentation.
> Run with --stacktrace option to get the stack trace.
> Run with --info or --debug option to get more log output.
> Run with --scan to get full insights.
> Get more help at

It seems the tasks fails for some reason but I’m not understanding why. Could someone please help?

That is a task that IntelliJ creates and tries to call.
So you should seek help from JetBrains (or Google if you use Android Studio) to find out and fix why it does not work as intended.
