Eclipse internal error while initializing Java tooling

Question

I am getting errors from Eclipse Indigo running on Windows 7 Ultimate. For each of the following items:

Android SDK content loader
Building workspace
Initializing Java Tooling
Loading data for Android 2.3.3
Loading data for Android 4.03

this error is thrown:

 An internal error occurred during: "Initializing Java Tooling".java.lang.NullPointerException

What should I do?

Answer 1

Close all open projects and exit Eclipse. Now you can open Eclipse without getting the error. Start opening your projects one by one to find which one causes the problem. This is most likely because you deleted a Device profile inside the AVD manager.

Or you can start working on a new workspace, (i.e. change your workspace), then try to import your project from the old workspace

Answer 2

Delete your existing workspace and then recreate the workspace and add your projects.

Answer 3

Just change the following values at "eclipse.ini" file to the following:

-Xms1024m
-Xmx2048m

Note:

• You can find the "eclipse.ini" file by right click eclipse icon on and select "Open file location".
• This error occurs because the eclipse is running out of memory, so we just increased the assigned memory for the eclipse application.

Answer 4

1. Close Eclipse.
2. Go to workspace folder in windows explorer and delete following folders:
   • .metadata
   • .recommenders
   • RemoteSystemsTempFiles
   • Servers
3. Open Eclipse and provide the same workspace folder again during launch.
