I'm stepping through the exercises in "Creating Eclipse Plugins". My unit tests are working fine (even in debug mode), but I'm having trouble with the regular run configuration. When I run it, the test instance comes up, but the plugin I've written doesn't appear to be available. There's nothing in the error log or problems view. In the "Plug-Ins" tab of the run configuration, I have both the main plugin and the test plugin enabled in the "Workspace" section. They're not enabled in the "Target Platform" section, and the only plugins enabled in "Target Platform" are the ones that I got from "Add Required Plug-Ins".|
Then I noticed the "Validate Plug-Ins" button in the "Plug-Ins" tab of the run configuration. When I clicked that, it gave me the following complaint:
Missing Constraint: Require-Bundle: org.eclipse.jdt.core; bundle-version="3.5.2"
Missing Constraint: Require-Bundle: org.junit4; bundle-version="4.5.0"
Here's the MANIFEST.MF files:
Bundle-Name: Favorites Plug-In
Bundle-SymbolicName: com.qualityeclipse.favorites; singleton:=true
As you can see, both of them have a "Require-Bundle" property which includes the value that it says is missing.
This could just be a red herring, but I can't find anything else wrong that might cause the run configuration to not run the plugin.

It only does a one-level search. In other words if you "require" a
plugin, and that plugin requires another plugin, that other plugin won't
be pulled in. I think it works better with required features instead of
The new p2 format will actually pull in all of the requirements.
