The google-java-formatter eclipse plugin doesn't change the format of my code

[gustabart]

Hi,
I drop the google-java-format-eclipse-plugin-1.20.0.jar file in dropins eclipse folder.
I set google-java-formatter in my eclipse workspace and project configuration.
However, the formatter hasen't effect over my code.

I do Ctrl-Shift+F or from the contextual menu, but the java code format remains the same.

My eclipse version is:

Eclipse IDE for Java Developers (includes Incubating components)
Version: 2023-12 (4.30.0)
Build id: 20231201-2043
OS: Linux, v.5.14.0-1052-oem, x86_64 / gtk 3.24.33, WebKit 2.42.5
Java vendor: Eclipse Adoptium
Java runtime version: 21.0.2+13-LTS
Java version: 21.0.2

I tried too with previous versions of the formatter plugin but the same result.
I thing that got my attention was the Preview. All in a same line:

Thanks in advance!

Hi,
i have the same problom with latest version of STS(Version: 4.22.0.RELEASE, based on Eclipse 4.31.0.v20240229-1022) and GJF-1.21.0.

When I run STS via terminal, i don't see any errors when trying to format code.

Could we add Bug label to this issue?

After I added these lines at the end of file SpringToolSuite4.ini it works :)

Adding these exports to eclipse.ini after -vmargs solved the problem for me!
