build.gradle.kts - import of java-classes fails in IntelliJ- Any hint?

[Gubaer]

Hi

when I import the gradle-josm-plugin in IntelliJ, imports for java classes like java.time.Duration in build.gradle.kts don't work. In kotlin files they don't work either.

I googled but I didn't come up with a solution.

Do you use IntelliJ too? Did you have the same problem? Do you have a workaround?

Thanks in advance!

Yes, I also use IntelliJ idea. But I didn't encounter this issue before.

If it is only classes from the JDK, it is probably the issue that IntelliJ can't find the JDK.
Does it only affect Kotlin files or also Java files?
Make sure that under File › Project Structure… › Project Settings › Project the project SDK is set correctly.
Under File › Project Structure… › Platform Settings › SDKs you can inspect the details of the available SDK choices or add a new one.

Does that already help?

Thanks!

I had to manually add the $JAVA_HOME/jre/lib/rt.jar to the SDKs classpath. Seems to be fixed now.
