Please document the role of Active profile in Eclipse configuration

[oliviercailloux]

The README states: “The plugin adds a google-java-format formatter implementation that can be configured in Window > Preferences > Java > Code Style > Formatter > Formatter Implementation.”

It is unclear what can be configured exactly, or whether anything can be configured, considering the note in the same file: “There is no configurability as to the formatter's algorithm for formatting. This is a deliberate design decision to unify our code formatting on a single format.”

Relatedly, the role of the Active profile dialog box is not clear.

I just tested changing the number of spaces in the active profile, and this seems to have no effect on Source / Format when the google-java-format implementation is selected.

Please add some explanations about what can be configured and which Active profile should be chosen or indicate if it is supposed to have no effect.

Possibly related to #260.

Also seeing the same thing. If the google-java-format formatter is selected (with 1.13.0 and the latest version of Eclipse), when I try to format code, absolutely nothing happens. If I go back to the Eclipse built-in formatter, it does format the code. I'm not sure if I'm missing a step or if the plugin is currently broken?

Still happening with the 1.15 release.

Same here. Does the documentation need to be updated, or are there anything I'm not doing right ?

Same here with Eclipse AND IntelliJ.

IntelliJ Scheme XML file.

[Lonzak]

Same here - unclear what to select in the "active profile". Tried all profiles but nothing happens when I format the code.
How is this supposed to work?

Here is a snapshot of a working setup:

Formatter implementation choice is provided by google java format extension.

Active profile choice is provided by importing https://raw.githubusercontent.com/google/styleguide/gh-pages/eclipse-java-google-style.xml

If you want to obtain a consistent result with cli or maven plugin formatting, you also need to remove all import group in organize imports setting:

If it still not work, check that you added the following options to eclipse launch (see https://github.com/google/google-java-format?tab=readme-ov-file#as-a-library)
