How can i pass JPMS --add-opens option to Kotlin compile task? I was testing the recent loom EA build (JDK 17, which has enabled strong encapsulation of some jdk packages) and failing with the following error.

The fix is to add --add-opens java.base/java.util=ALL-UNNAMED option when running java.
I tried to set this option in all the following places like
1. gradle properties org.gradle.jvmargs=
2. export JAVA_OPTS="--add-opens java.base/java.util=ALL-UNNAMED"
3. java compile task

compilerArgs.addAll(
                listOf(
                    "--enable-preview",
                    "--add-opens",
                    "java.base/java.util=ALL-UNNAMED"

4. Kotlin compile task

freeCompilerArgs += listOf(
                "-progressive",
                "-Xjavac-arguments=" + listOf(
                    "--add-opens",
                    "java.base/java.util=ALL-UNNAMED"
                ).joinToString(separator = ",")

None of these options worked and still getting the above error. Any hint on how to open JDK modules to my all application packages?

I've answered in https://youtrack.jetbrains.com/issue/KT-44266#focus=Comments-27-4639508.0-0.

Basically you need to use kotlin.daemon.jvm.options since the Kotlin compiler is running in a separate process
