NPE during eclipse start on "Initializing Java Tooling"

Question

Just installed eclipse 3.6.2 JDK 1.6.0 update 24. And followed instructions on http://developer.android.com/sdk/installing.html

But eclipsed is failing with NPE. Also repros with eclipse 3.5.2

Any help would be very much appreciated.

Here is the log:

Not sure why this was closed as too localized--many people have reported the same problem: http://stackoverflow.com/questions/10140732/error-with-parsing-android-sdk-content-and-initializing-java-tooling-in-eclipse/10449082#10449082, http://stackoverflow.com/questions/5019051/problem-with-android-sdk-content-loader — Jeff Axelrod, May 04 '12 at 12:56
For me, the source of the `NullPointerException` problem was a host-side Junit test project that references (and tests) code from an Android project. It didn't have a `project.properties` file. It's not an Android project, but for some reason the newer versions of the SDK somehow expects the file there. To fix the problem, I just copied a `project.properties` file from an Android project to the host unit test project. — Jeff Axelrod, May 08 '12 at 15:17

Resolved!

Uff, I had projects in older eclipse installation which I think were throwing error with new installation.

Learning: Switch to new the workspace with new eclipse install.

Alternatively, you may delete (back it up beforehand) the .metadata directory in your workspace. – Jon Willis Apr 15 '12 at 00:06
I switched to a new workspace using -data switch in command line but that didn't help. Deleting .metadata as Kim suggested did the trick for me. – pm_labs Aug 04 '12 at 13:28
