Using Eclipse CDT with the Firefox Nightly code

I downloaded Mozilla-central and built it. I am able to run Firefox Nightly using ./mach run. Now I am following the instructions of MDN on how to use Eclipse CDT with Mozilla code. I downloaded Eclipse CDT on my mac and installed it. When I execute the following command:

./mach build-backend -b CppEclipse

It raises an exception saying: Failed to launch eclipse to import project. Ensure 'eclipse' is in your PATH and try again

I tried to add the eclipse's directory (Applications/Eclipse.app) to my PATH environment variable but I still get the same error.

Here is the complete trace:

0:00.46 /Users/****/src/mozilla-central/obj-ff-dbg/_virtualenvs/init/bin/python /Users/****/src/mozilla-central/obj-ff-dbg/config.status --backend CppEclipse Reticulating splines... 0:02.99 File already read.

" Exception: Failed to launch eclipse to import project. Ensure 'eclipse' is in your PATH and try again

Also, using the command:

./mach ide eclipse

I again get the same message:

Eclipse CDT 8.4 or later must be installed in your PATH. Download: http://www.eclipse.org/cdt/downloads.php

How can I resolve this issue? I just need to open Firefox nightly in Eclipse to be able to get the call-graph and navigate through its source code.

Solution

  • Run Eclipse first, then:

    1- Command:

    ps -ef |grep -i ecli

    Output:

    501 6410 1 0 2:57pm ?? 0:44.98 /Applications/Eclipse CPP.app/Contents/MacOS/eclipse 501 6428 6365 0 2:57pm ttys001
    0:00.00 grep -i ecli

    2- Add the binary to the path:

    export PATH=/Applications/Eclipse\ CPP.app/Contents/MacOS/:$PATH

    3- Test it:

    which eclipse
