[FIXED] How to open a file in the current open Eclipse workspace from command line?

Issue

I have Eclipse already running, and I want to be able to open a file and jump to a line number from CLI.

I want the file to open in the current open workspace. I am trying this:

/Applications/Eclipse.app/Contents/MacOS/eclipse --launcher.openFile test_file.c:401

However, I am getting an error because the default workspace is already open, and its asking me to choose another workspace.

if I simply use open text_file.c it works just fine, but doesn't jump to the line number of course.

Edit: Even after starting in a new session, and removing the line number, Eclipse doesn't open the file. It only opens the application (Eclipse). however if I use open -a eclipse filename the file opens successfully

Solution

Thanks to Lili for the correction:

1. Opening a file in the same workspace via command line does not work on mac, bug1

2. Opening a file/linenumber in eclipse is not supported
