To answer my own post, and after some digging, the main problem is that the PDE
in 3.1 generates a badly broken Ant build script for plug-ins that depend on
plug-ins that have "linked content". Specifically, the classpath in the
generated build.xml claims that the jar files for the linked content plug-ins
resides within those plug-ins' project folders.
For example, if plug-in com.foo depends on org.eclipse.core.resources, and
org.eclipse.core.resources was imported as "binary with linked content",
invoking "Create Ant Build File" on com.foo produces an Ant script with
classpath entries like this:
<classpath>
<pathelement path="../org.eclipse.core.runtime/eclipse-
3.1/plugins/org.eclipse.core.runtime_3.1.0.jar"/>
<pathelement path="../org.eclipse.core.runtime/org.eclipse.core.runtime_
3.1.0.jar"/>
...
</classpath>
Here's the relevant Bugzilla entry:
