Eclipse on Mac 10.8 - Installed 1.7.0 JRE / JDK, but Eclipse won't launch

• Installed Java SE 1.7.0u10 from Oracle w/ their installer package

• Downloaded and unpacked Eclipse Juno (4.2.1)

• Double click Eclipse

Answer 1

I found the same problem (Mac OS X 10.9.2, Java 1.7.0_53b13, Eclipse Kepler). The workaround was quite easy:

1. Find the executable in Finder (CMD+Click on Eclipse's icon in the Dock)
2. Remove the icon from the Dock
3. CTRL+Click on the executable in Finder
4. ALT+Open (to allow the execution of a non-signed application)
5. Eclipse opens normally and without any problem
6. Re-dragged the program onto the Dock
