This is presumably application for all packages on Mac but I am testing parallel package. Starting with Luna M4 (new build process; M3 worked fine) Launching from the command line no longer works as it did before. The Mac package no longer works when launched from the command line. I have always done: tar -xf foo.tar.gz cd eclipse ./eclipse -showlocation -data /path/to/workspace Now a popup complains "Alert The Eclipse executable launcher was unable to locate its companion shared library. So I like the command line invocation to keep my command lines and my workspaces straight for testing lots of builds. Double-clicking on the Eclipse.app from the mac Finder does work just fine, however. Which is how most folks would probably use it. Gunnar Wagenknecht on epp-dev observed that if you instead cd to: cd eclipse/Eclipse.app/Contents/MacOS/ Then it works as before, and he remarked "So the error message indicates that it’s having trouble finding the shared library that’s typically shipped with the executable. That’s because it doesn’t have the eclipse.ini in the "eclipse" path. However, the ini is in the Eclipse.app/Contents/MacOS folder. Thus, launching from that folder works fine on the command line."

Setting target milestone to 4.4M6 - I didn't find the time to solve this in time for M5.
The 'eclipse' in the root folder is supposed to be a soft link to the eclipse int he MacOS folder. This might actually be a p2/PDE/Tycho problem.
Confirmed it is really the missing symbolic link in the tar.gz created by Tycho: On the server before creating the tar archive (correct): $ ls -il eclipse Eclipse.app/Contents/MacOS/eclipse 2643298 lrwxrwxrwx 1 mknauer mknauer 34 Mär 3 07:12 eclipse -> Eclipse.app/Contents/MacOS/eclipse 2643294 -rwxr-xr-x 1 mknauer mknauer 25104 Jan 23 17:52 Eclipse.app/Contents/MacOS/eclipse Content from the tar archive without the symbolic link: $ ls -il eclipse Eclipse.app/Contents/MacOS/eclipse 120277 -rwxr-xr-x 1 mknauer mknauer 25104 Jan 23 17:52 eclipse 123068 -rwxr-xr-x 1 mknauer mknauer 25104 Jan 23 17:52 Eclipse.app/Contents/MacOS/eclipse Closing this bug as duplicate of bug 424769 *** This bug has been marked as a duplicate of bug 424769 ***
