I get ```org gradle api GradleScriptException A problem occu kotlinlang #arrow-contributors

Building with a JRE or JDK9 is currently not supported

Maybe tools.jar is no more used and it is a bad check to have?:

Copy code

def toolsJar = Jvm.current().getToolsJar()

    if (!toolsJar)
        throw new GradleException("tools.jar not found at your JAVA_HOME dir ${Jvm.current().getJavaHome().getAbsolutePath()}.\n" +
                "Building with a JRE or JDK9 is currently not supported.")

Hi @Marius Kotsbak 🙌 Please, try it with JDK8 instead of JDK11

Probably works, but shouldn't it support newer than JDK 8?

Well, 8-13 they say: https://kotlinlang.org/docs/reference/faq.html#which-versions-of-jvm-does-kotlin-target

I can't get it to use JDK 8 either, as it detects and choses 11 during import from Gradle in IntelliJ, which fails. How do you do it?

“tools.jar not found at your JAVA_HOME dir ${Jvm.current().getJavaHome().getAbsolutePath()

point your JAVA_HOME to it

Hmm maybe that works before starting IntelliJ. Looks like I can bootstrap by commenting out those lines.
