Add maven plugins that reuse Eclipse formatter configurations.
The Eclipse formatter configuration can be used interactively in Eclipse while editing code.
The maven plugins can do batch re-formatting on existing code.
The formatter configuration can be committed into the code repo for all to share and use consistently across the projects.

The command "mvn formatter:format spotless:apply" produces output like below:

[INFO] --- formatter-maven-plugin:2.8.1:format (default-cli) @ aai-traversal ---
[INFO] Using 'UTF-8' encoding to format source files.
[INFO] Number of files to be formatted: 211
[INFO] Successfully formatted:          211 file(s)
[INFO] Fail to format:                  0 file(s)

The quality of the result can be gauged by triggering the checkstyle audit with "mvn process-sources".
