问题
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 using eclipse. Does anyone have any code examples that would allow me to do this? I would also like to use this standalone, so the specific jars that are used would be nice.
回答1:
Apparently you can directly invoke Eclipse's code formatter from the command line.
回答2:
Never tried to pull something like that off, but I remember seeing once a class called:
org.eclipse.jdt.core.formatter.CodeFormatterApplication
Perhaps that is some standalone entry point into the formatting mechanism, though I've never tried or investigated further.
回答3:
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 <path to virtual machine> -application org.eclipse.jdt.core.JavaCodeFormatter [ OPTIONS ] <files>
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.
