Document Gradle/IntelliJ configuration issues

IntelliJ reports the following:

Found invalid Gradle JVM configuration
JDK 17.0.3 isn't compatible with Gradle 7.5.1.
Are we now requiring some other version of Java?

Attempting to build using the runLfc task gives this:

This is a strange error. Gradle 7.5.1 is compatible to Java 17 and it works fine on my machine. Also Marcus set up Intellij recently without problems.

Does it work if you manually run ./gradlew runLfc --args test/C/src/Minimal.lf on the command line? Which version of IntelliJ do you use?

Command-line gradle build works fine. Version of IntelliJ:

Ok, I think your IntelliJ is too old. According to this stackoverflow answer IntelliJ 2021.2.3 does not support Graddle 7.3 or newer.

Sorry, I updated IntelliJ to 2022.2.3 (Oct. 4, 2022) and the build still fails:

Which version of Java is IntelliJ using?

BTW, I marked this as invalid because the title is wrong...

^, iirc one needs to pick both normal JDK and Gradle JVM in intellij settings, and it's normal that messes up by using automatically detected ones

Looks like this has been resolved. We should update the website with a mention of this.
