Answer 1

It is a bug in pdt that seems to be fixed: https://bugs.eclipse.org/bugs/show_bug.cgi?format=multiple&id=350139

(I know I'm answering pretty late, but it will help other people that come from google)

---

edit: how I fixed it on my computer (and I don't recommend you to do it like me):

Got the latest stable nightly build of pdt from https://hudson.eclipse.org/hudson/job/cbi-pdt-3.0-indigo/ which for me was: https://hudson.eclipse.org/hudson/job/cbi-pdt-3.0-indigo/166/artifact/build/N201107150957/

There seems to be a way to update eclipse plugins by using pdt-Update-.zip files explained here Getting Eclipse PDT nightly build from Hudson . I couldn't do that on my computer and I didn't had time to investigate why it didn't worked. I got the other zip file (pdt-SDK-.zip), removed the old plugins from eclipse library directory and put the new ones instead. It didn't work, the PHP perspective was nowhere to be found after that. So, I did a dirty hack: took org.eclipse.php.core_3.0.0.v201107150957.jar from the archive, removed the old one from the eclipse library directory (org.eclipse.php.core_3.0.0.v20110516-1100.jar in my case) and renamed the new one like the old one.

I am aware that this may break things and I don't recommend to other people to do that unless they do it as a temporary hackish fix :-)

I should have tried PDT 2 though...

Answer 2

NEW SOLUTION: There is new PDT Indigo bundle (3.0.2) which runs fine for me, out-of-the-box: http://code.google.com/p/zend-sdk/downloads/list

OLD SOLUTION (PDT 3.0.0):

Thank you Valentin, I could fix my Eclipse. For me it worked from your link like that:

1. Open https://hudson.eclipse.org/hudson/job/cbi-pdt-3.0-indigo/lastStableBuild/artifact/build/
2. Click on build number N*
3. Download pdt-Update-N*.zip
4. In Eclipse goto "Install New Software"
5. Create a new site with archive and choose the downloaded zip
6. Now PDT is updated from the downloaded zip

Link updated, thanks to Daff!

Answer 3

If anyone still looking for this, it just happened to me, and found out that closing "AMD gaming evolved" application fixed it.. If I open it again it happens, just close that if you have it and try

Answer 4

Cleaning up my Available Software Sites preferences (Help>Install New Software), then updating Eclipse again (Help>Check for Updates) removed this error for me.
