eclipse - How to locate the Path of the current project directory in Java (IDE)?

Question

I am trying to locate the path of the current running/debugged project programmatically in Java, I looked in Google and what I found was System.getProperty("user.id"), which didn't get me the project's path.

I know the command Environment.currentDirectory in C# gives the path of the current running/debugged project,so I am sure there must be a similar way in Java, too.

So I am asking if anyone could tell me or give me a code to how locate the path of the currently running/debugged project programmatically?

edit: i am writing plugin which loads with eclipse start. the plugin adds a button to the workbench of eclipse, with in the code of the plugin when i click the button i search for the current directory path.

my purpose is that when for example i debug a project and then click the button, a window will pop up presenting the debugged project's path, thanks

Two ways

System.getProperty("user.dir");

or this

File currentDirFile = new File(".");
String helper = currentDirFile.getAbsolutePath();
String currentDir = helper.substring(0, helper.length() - currentDirFile.getCanonicalPath().length());//this line may need a try-catch block

The idea is to get the current folder with ".", and then fetch the absolute position to it and remove the filename from it, so from something like

/home/shark/eclipse/workspace/project/src/com/package/name/bin/Class.class

when you remove Class.class you'd get

/home/shark/eclipse/workspace/project/src/com/package/name/bin/

which is kinda what you want.
