Spotless Maven Plugin fails on Java 25 EA

[scordio]

When executing spotless-maven-plugin:2.44.4:check on Java 25 Build 19, I get the following error:

Execution default of goal com.diffplug.spotless:spotless-maven-plugin:2.44.4:check failed: An API incompatibility was encountered while executing com.diffplug.spotless:spotless-maven-plugin:2.44.4:check: java.lang.NoSuchMethodError: 'java.util.Queue com.sun.tools.javac.util.Log$DeferredDiagnosticHandler.getDiagnostics()'

It seems that DeferredDiagnosticHandler::getDiagnostics is no longer binary compatible as it returns a List<JCDiagnostic> in Java 25 instead of a Queue<JCDiagnostic>.

After a closer look at the problem, I realized it's google-java-format failing, not Spotless.

See also google/google-java-format#1247.

Sorry for the noise!

I'm reopening this to signal that an upgrade to google-java-format 1.27.0 is required when running on Java 25:

<googleJavaFormat>
  <version>1.27.0</version>
</googleJavaFormat>
