Can the Eclipse Java formatter be used stand-alone

Question

Is there a way to use the formatter that comes with eclipse, outside of eclipse? I would like to format some java files using my formatter.xml file that I have configured u

Answer 1

Here's the offical eclipse docs on how to do this

Dump of those docs:

Running the formatter application is as simple as running the org.eclipse.jdt.core.JavaCodeFormatter application from the commandline:

eclipse -vm  -application org.eclipse.jdt.core.JavaCodeFormatter [ OPTIONS ] 

When invoked on MacOS, the paths to point to the configuration file or the source files can be relative, but they will be computed from the location of the eclipse.ini file. This is a limitation of the Eclipse launcher on MacOS. On all other platforms, the relative paths are computed relative to the current user directory.

Java source files and/or directories to format. Only files ending with .java will be formatted in the given directory.

-config

Use the formatting style from the specified properties file. Refer to Generating a config file for the formatter application for details.

-help

Display the help message.

-quiet

Only print error messages.

-verbose

Be verbose about the formatting job.
