I haven’t had much luck installing PDT on Eclipse lately. I’ve been getting an error when I try to install from the PDT site on Zend:
Cannot complete the request. See the details.
PDT SDK Feature will be ignored because it is already installed.
Cannot find a solution satisfying the following requirements Match[requiredCapability: org.eclipse.equinox.p2.iu/org.eclipse.swt/[3.4.0.v3448f,3.4.0.v3448f]].
Here’ s the original links from eclipse and zend:
http://www.eclipse.org/pdt/release-notes/pdt2_0.php
http://www.zend.com/community/pdt
And here’s the zend update site:
http://downloads.zend.com/pdt/
This seems to only have the debugger?
Here’s a few links that seem to be helpful:
http://www.howtoforge.com/setting-up-eclipse-pdt2.0-on-eclipse3.4-ganymede
The above has out of date links, since the DLTK, there is out of date, and the current one is installed in 3.4.1
This page helps, with a link (again) to an old DLTK:
http://wiki.eclipse.org/PDT/Installation
but it has a vital link to the actual PDT update site:
download.eclipse.org/tools/pdt/updates/2.0/
Also note the clue in the screenshot to only check the SDK, not the Runtime
It also has a link to the supposed correct dependencies:
http://www.eclipse.org/pdt/downloads/
The debugger still won’t install, and my guess is that it should have a dependency on
org.eclipse.equinox.p2.ui
not
org.eclipse.equinox.p2.iu
I also tried downloading the all in one and copying everything from features and plugins that started with org.zend.* to my eclipse install.

I see a similar complaint when trying to install RadRails:
Cannot complete the request. See the details.

I was having the same problem, but it was resolved by installing\updating Eclipse SDK.
I had the same result as cmsjr.
I had to update the Eclipse SKD, uninstall most of the elements of the DLTK that a site recommended and replaced them with the Core Frameworks SDK. Then installed PDT SDK feature and it completed successfully.
i’m having the same issue, issue fixed :D but i am getting same error but with jdt :(:S
I was having this issue with the Maven POM editor installation. An eclipse update via the standard eclipse update site fixed the issue. Also set it to automatic install so that such issues would be not come up every now and then.
I’m having the same issue, and while trying to install the Maven plugin. I’ve already updated to , but it still complains about this. Do I have to update anything from ?
David-
What problem specifically are you getting? I’m afraid that even after I got PDT working, I started getting frequent errors while typing, and had pretty much given up on PDT 2.0. It looks to me like Zend is trying for the “appearance of open source” with PDT, but makes it very difficult to gather all the required parts. That said, it does look like they have some new stuff on their download site http://downloads.zend.com/pdt/ including a features and plugins folder, but it looks like still just the debugger and pointing to the old eclipse 1.1 PDT update site for the actual PDT.
I had some luck with just copying the all-in-one into an existing eclipse build, but it worked once, and didn’t work another time. Frankly, I don’t see how anyone manages to work with Eclipse. You’ve essentially got to grab a snapshot and hope the other tools have done the same. Reminds me of CPAN, only worse.
