Hi,
you can only build Lucene with the shipped “gradlew”, not an arbitrary Gradle version: $ ./gradlew assemble To build Lucene and test on later Java versions, you need two JDKs installed and set environment variables. JAVA_HOME must point to JDK 11 RUNTIME_JAVA_HOME can point to anything (e.g. 16 or 17). By this Gradle runs with a supported environment for gradle, but compilation, tests,… are executed in the RUNTIME_JAVA_HOME.
