I just verified removeUnusedImports works on Gradle 5.4.1 w/ Java 11.0.4 and spotless 3.24.1!

Class javax/tools/JavaFileManager$Location is located in module java.compiler provided by the JDK 9.

“Someone” has to declare the usage of module java.compiler somewhere:

  1. google-java-format
  2. spotless
  3. Gradle project build configuration (here JUnit 5)
  4. Gradle environment (daemon?)
