Can you post the full output? Is this while running ./gradlew? I tried OpenJDK 20 and the build appears to work here:

❯ java --version
openjdk 20.0.1 2023-04-18
OpenJDK Runtime Environment Homebrew (build 20.0.1)
OpenJDK 64-Bit Server VM Homebrew (build 20.0.1, mixed mode, sharing)

❯ ./gradlew

Hi!

I had the same error with jdk20. After changing gradle-wrapper.properties file in gradle/wrapper folder to a newer gradle binary link I was able to successfully build the plugin.

I changed the distributionUrl to distributionUrl=https\://services.gradle.org/distributions/gradle-8.1.1-bin.zip

Thanks for the info. I've updated the Gradle wrapper to 8.0.1 (by running gradle wrapper). Let me know if there are other issues with JDK 20.
