The project get stuck at initial import when I open Android Studio, this started happening with AS Hedgehog Canary 6: worked in Canary 5.

[tapchicoma]

This is purely AS import issue and does not relate to Kotlin build tools

[Daniele Segato]

Are you saying its AS and not Intellij?

[Daniele Segato]

(I do not see any android-specific in that stack trace, how do you know?)

[tapchicoma]

AS has own implementation of import based on IJ/platform

[Daniele Segato]

do you mean when you do “import project”?
this is an existing project, I just updated AS and opening it lead to this issue.
I’m not sure if the term “import” is the right one.

[Daniele Segato]

probably “open existing / previously imported project” is a more accurate description

[dave08]

Any solution?

[dave08]

My import gets stuck, and nothing works...

[dave08]

Oh, just looked at that issue, and trying some things from there...

[Daniele Segato]

I reproduced the issue for Google (see the issue tracker)

The issue happens because of some Gradle plugin + usage or buildSrc. And can be worked around by disabling the plugin / not using buildSrc directory or adding a flag to android studio. All is in the issue I linked

[dave08]

Yeah, I removed the buildSrc, it still didn't work, but when I set the flag in the registry to false it finally worked, thanks!
