Description Jim des Rivieres

2002-05-08 01:52:00 EDT

Internal test build (20020507)

The org.eclipse.ui plug-in has sprouted a new fragment org.eclipse.ui.win32.

0. Fresh workspace
1. Import org.eclipse.ui and org.eclipse.ui.win32

Observe: 

(1) Problem Occurred "Plug-in Import"
(2) Details "Problem while importing "org.eclipse.ui". Name collision.

Expectation:
- there should not be any error here
- error message should be more meaningful than "Plug-in Import"

2. Delete both plug-ins and content
3. Import org.eclipse.ui
4. Import org.eclipse.ui.win32

Observe: No problems doing them one at at time.

5. Delete both plug-ins and content
6. Import org.eclipse.ui.win32
7. Import org.eclipse.ui

Observe: No problems with this order either.

One interesting property about org.eclipse.ui.win32 is that it must be compiled
*after* org.eclipse.ui. (Although I don't see how that would matter.)

Can you verify that this is not the same problem as with SWT? Check that the 
same library is not listed twice (once in UI plugin.xml and again in win32 
fragment.xml).

There are no signs of this.

fragment.xml
==================
<?xml version="1.0" encoding="UTF-8"?>
<fragment
   id="org.eclipse.ui.win32"
   name="%fragmentName"
   version="1.9.0"
   plugin-id="org.eclipse.ui"
   plugin-version="1.9.0">
   
  <runtime>
    <library name="workbenchwin32.jar">
      <export name="*"/>
    </library>
  </runtime>

</fragment>
==================

plugin.xml begins

Found it. Added checks to avoid duplicate entries while computing the classpath.
