Any idea why my Eclipse isn't starting?

The eclipse.ini has the following:

-startup plugins/org.eclipse.equinox.launcher_1.1.0.v20100507.jar --launcher.library plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.0.v20100503 -product org.eclipse.epp.package.jee.product --launcher.defaultAction openFile --launcher.XXMaxPermSize 256M -showsplash org.eclipse.platform --launcher.XXMaxPermSize 256m --launcher.defaultAction openFile -vmargs -Dosgi.requiredJavaVersion=1.5 -Xms40m -Xmx512m 

The error log in workspace log file shows this

Why is Eclipse not showing errors?

You need to open the eclipse Markers view ( Window->Show View->Markers ), it will show all errors about your project, if you correct all the errors, your problem will most likely be solved.

How do I fix Eclipse not responding?

If there is a project you earlier imported externally (outside of Workspace), that may cause this problem. If you can access Eclipse try to remove it. If you are getting the 'No responding at startup', then go delete the file at source. This will solve the problem.

Why Java is not working in Eclipse?

Verify if you have installed a different version of JDK/JRE from your Eclipse. If you have installed 64 bits JDK version and your Eclipse version is 32 bits, it won't work. They have to be equal. If appears: "Error: This Java instance does not support a 64-bit JVM.

It seems to fail when trying to restore the workspace.

Try:

  1. Open a new workspace. If it has been set to use a default, go to <Eclipse_root_dir>\configuration\.settings\org.eclipse.ui.ide.prefs and set SHOW_WORKSPACE_SELECTION_DIALOG to true

  2. Try deleting <workspace>/.metadata/.plugins/org.eclipse.core.resources/.snap

  3. As suggested in a comment: If using Eclipse 4, you may have to delete the file .metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi aswell.
