Hi again, I'm trying to run the

konsist

project on my local machine (Macbook pro M2), with JVM 21 installed (

openjdk 21

), and when trying to sync Gradle I'm getting the following error:

* What went wrong:
A problem occurred configuring project ':buildSrc'.
> Failed to calculate the value of task ':buildSrc:compileJava' property 'javaCompiler'.
   > No matching toolchains found for requested specification: {languageVersion=19, vendor=any, implementation=vendor-specific} for MAC_OS on aarch64.
      > No locally installed toolchains match and toolchain download repositories have not been configured.

I did not see any list of requirements in the documentation regarding to how to build the project locally, am I missing something?

Try to set JDK manually. You can install missing JDKs directly from IntelliJ IDEA - click on the

Module SDK

combo box and select

+Add SDK

. BTW I have updated Contributing page

Seems that in my specific case the problem was that the JDK of Gradle was not set to version 19 (or newer), and I had to do this update on the project

You can also add this:

kotlin {
    jvmToolchain(19)
}

to the build.gradle inside the

lib

module! If the IntelliJ doesn't work properly.
