Build Identifier: 20090920-1017 I have been successfully working with the Eclipse IDE for C++ Developers for several months. However, when I try to install JDT on top of this existing installation, Eclipse keeps bugging me about not being able to complete the request and hangs forever on "Cannot complete the request. Generating details." This looks like a problem with automatically resolving the neccessary package dependencies. Reproducible: Always Steps to Reproduce: 1. Open Eclipse -> Help -> Install New Software 2. Select "All available sites" 3. Check Java Development 4. Press Next 5. Get this: Cannot complete the install because of a conflicting dependency.

What is the letter before the build identifier I or M? Which JDT version do you try to install and where did you get it?
I cannot reproduce on Windows: Installing CPP from the zip got on the Eclipse download site + Install New Software works like a charm on my Win/XP machine... Would it be possible to test a fresh install on a brand new workspace on your machine to see if you can reproduce or not?
(In reply to comment #1) > What is the letter before the build identifier I or M? It's an M. Didn't appear in the About Eclipse window, but was to be found in the Installation details: M20090917-0800 > Which JDT version do you try to install and where did you get it? I didn't any custom sites. Amongst lots of others, the Java Development source was readily available since I first installed this version of Eclipse. I'm also sure that there was no previously installed version of Eclipse since the machine was brand-new when I performed the install.
(In reply to comment #2) > I cannot reproduce on Windows: Installing CPP from the zip got on the Eclipse > download site + Install New Software works like a charm on my Win/XP machine... The problem occured only during an "online" install. I didn't try downloading a ZIP file and installing it manually. > Would it be possible to test a fresh install on a brand new workspace on your > machine to see if you can reproduce or not? I just did that and it worked out of the box. Surprisingly, all the entries in the install dialog look way different in the current version of Eclipse, being grouped and organized far more than they were before. However, the build that I had installed beforehand is not older than 6 or 7 weeks... All in all I think this "bug" can be marked as resolved or removed at all. A workaround for my older version of Eclipse was installing the Java Development components one by one.

It seems to be a specific issue with your previous installation and/or your workspace, hence it will be difficult to track the real origin of the problem without debug it on your box... Close this bug for the while, if you have any other similar issue then reopen it and we'll see on which component to reassign it as it's clear now that it was not a JDT/Core issue...
