Hey, Are there any update on this issue - https://youtrack.jetbrains.com/issue/KT-74394/KGP-isolated-projects-Something-has-been-appended-to-this-collector-already

We are looking at migrating our project to gradle 8.12/8.13, and noticed similar issue when IDE is in sync mode. We have not enabled project-isolation or config-cache-parallel flag.

[ritesh]

kotlin.internal.collectFUSMetrics=false

There's a workaround mentioned, but unsure if it will have any side-effects or such

Gradle - 8.12.1

Would be great to know, what will be the impact of disabling that flag and if it's going to fix it, before we move ahead with it. And and in which KGP version that issue will be fixed - that will help us to keep an eye on it and move forward with removing that flag in that release.

Would be nice to see some documentation of the fus metrics at all. What does it do?

[tapchicoma]

Should be fixed in 2.1.20-RC2

[tapchicoma]

in general 2.1.0 was fully tested only with Gradle 8.10 and some problems with newer Gradle versions are expected

[ritesh]

Any impact if we move ahead with turning the fus metric flag off, for the time being

@tapchicoma

[tapchicoma]

you may turn it off, tomorrow RC2 should be published - please check it

[ritesh]

Ahh nice, thank you.
