I have a gradle/kotlin-jvm project with 76 files and 4255 total LOC.
The compileKotlin task takes ~20 minutes.
I would like to learn how to debug this.

Is there any guide on extracting this information from the compiler?

[Robert Jaros]

have you tried giving more ram for the jvm?

[rahulsom]

org.gradle.jvmargs=-Xmx2g

[rahulsom]

This is weird since I’ve got another project with 125 files/6401 LOC and it completes compileKotlin in about 10-15 seconds.

Use the scan task to see where is the problem

[rahulsom]

That tells me it was the compileKotlin task that took too long.

[rahulsom]

I think I need insight into why it took so long.

[rahulsom]

Bumping memory from 2g to 4g doesn’t make it noticeably better either. I don’t see why the compiler would need more than 2g though.

[rahulsom]

It is clocking 100% CPU which is understandable but only takes about 1.1GB of RAM per Activity Monitor.

do you use kotlinx.html? https://github.com/Kotlin/kotlinx.html/issues/147

[rahulsom]

Yep! I isolated the problems to kotlinx-html

[rahulsom]

Thanks for pointing me to that!
