I was trying to install the eclipse plug-in for an assignment. But the problem is, my installed eclipse's version is mars, which means I can not find the location of the 'plugins' directory, which was used to save plug-in jar files.
I've updated the eclipse Luna to Mars recently. When I installed(unzipped) the eclipse luna, I remember that there was 'plugins' directory and other things (including eclipse.app) were in the 'eclipse' directory. However, The mars, archive file just gives me an eclipse.app!..
Could you tell me how to add the plugin(*.jar, in my case, UMLet) to eclipse mars on Mac OSX? I have to do my assignment.. The due is coming..
Eclipse Mars on the Mac has been reworked to be a proper Mac application with everything included in the Eclipse.app package.
The new path for the plugins is
/Applications/Eclipse.app/Contents/Eclipse/plugins
If you are looking at '/Applications' using the Mac Finder you will just see 'Eclipse'. You have to right click on 'Eclipse' and choose 'Show Package Contents' to see the contents.
Just putting things in the Eclipse plugins directory may not work. If at all possible you should use a proper Eclipse update site (sometimes called a repository) with 'Install New Software'.
Note most Eclipse installs now use 'oomph' which installs in a different location - see this answer
