How do I prevent Eclipse from hanging on startup?

Question

I am using Eclipse 3.3 (\"Europa\"). Periodically, Eclipse takes an inordinately long time (perhaps forever) to start up. The only thing I can see in the Eclipse log is:

Answer 1

I used eclipse -clean -clearPersistedState and that worked for me.

Warning: This may remove all projects from the workspace.

Answer 2

I had a similar problem after I updated eclipse on Mavericks. Eventually I found that in the eclipse plugins directory the com.google.gdt.eclipse.login jar had version numbers at the end. I removed the version number from the name and it all started fine :)

Answer 3

Windows -> Preferences -> General -> Startup and Shutdown

Is Refresh workspace on startup checked?

Answer 4

This may help

In your eclipse,

1) Go to Help

2) Click Eclipse marketplace

3) search - optimizer

install "optimizer for eclipse"

Answer 5

UFT causing issues with RDz (Eclipse based) after install These suggestions will allow to work around this situation even with the environment variables in place and with corresponding values.

Note: Conflicting application will not be recognized in a java context because it is being excluded from the java support mechanism.

1. Impact: Excludes Add-ins support from hooking to conflicting application executable via Windows Registry Editor Requirement: The application must be started by an EXE file, except Java.exe/Javaw.exe/jpnlauncher.exe

Instructions:

a. Locate the executable filename of the application conflicting with add-in(s) support. Either use the Task Manager or the Microsoft Process Explorer.

b. Open Windows Registry Editor.

c. Navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Mercury Interactive\JavaAgent\Modules For 32bits applications on Windows x64: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Mercury Interactive\JavaAgent\Modules

d. Create a DWORD value with the name of the conflicting software executable filenmae and set the value to 0.

Answer 6

I did this:

1. cd to .metadata.plugins\org.eclipse.core.resources
2. remove the file .snap
3. Noticed the Progress tab was doing something every few seconds..it seemed stuck
4. Exit eclipse (DO NOT FILE|RESTART HERE OR YOU HAVE TO GO BACK TO STEP 1 AGAIN)
5. Open eclipse again.

Using -refresh or -clean when starting eclipse did not help.
