You are not using java 8, as shown by your maven output. We have not made sure yet that Flink can be built on Java 16.

I am trying to build the Apache Flink project on my local machine and it seems like failing due to spotless issues. I am running the build on mac with java 8 xyz% java -version java version "1.8.0_301" Java(TM) SE Runtime Environment (build 1.8.0_301-b09) Java HotSpot(TM) 64-Bit Server VM (build 25.301-b09, mixed mode) Following is the error [ERROR] Failed to execute goal com.diffplug.spotless:spotless-maven-plugin:2.4.2:check (spotless-check) on project flink-annotations: Execution spotless-check of goal com.diffplug.spotless:spotless-maven-plugin:2.4.2:check failed: java.lang.reflect.InvocationTargetException: class com.google.googlejavaformat.java.RemoveUnusedImports (in unnamed module @0x4bc9389) cannot access class com.sun.tools.javac.util.Context (in module jdk.compiler) because module jdk.compiler does not export com.sun.tools.javac.util to unnamed module @0x4bc9389 -> [Help 1] We are getting the issue due to unused imports, so either we can remove the spotless at all or somehow configure it to ignore the warning for specific projects. Any ideas to build the project locally will be helpful.
