I use the latest google-java-format Intellij plugin based on google-java-format 1.9. As I understand it, this version should support Java 14/15 features like switch expressions and text blocks. In our case if any of the mentioned language features are used formatting stops working.

Just wanted to ask whether this may be a bug in my setup or if you're seeing the same problems?

Intellij IDEA Version: Ultimate Edition 2020.2.3 (Build #IU-202.7660.26, built on October 6, 2020)

Operating System: Ubuntu 20.04.1 LTS

Here is a small example:

public class FormatTest {
  enum Test {
    A, B
  }
  public static void main(String[] args) {
    String foo =                  "This should not be here";
    Test t = Test.A;
    String foobar = switch(t) {
      case A -> "foobar";
      case B -> "barfoo";
    };
    String xyz = """
            """;
  }
}

When I try to format this inside the IDE nothing happens. It shows that it's reformatting the code but the formatting doesn't change.There is no error as far as I can see.

However, formatting it with google-java-format-1.9-all-deps.jar it outputs correctly:

public class FormatTest {
  enum Test {
    A,
    B
  }

  public static void main(String[] args) {
    String foo = "This should not be here";
    Test t = Test.A;
    String foobar =
        switch (t) {
          case A -> "foobar";
          case B -> "barfoo";
        };
    String xyz = """
            """;
  }
}

Any help concerning this issue would be very much appreciated! Thanks for your great work!
