I'm probably missing something, but I can't get this to work. I'm trying to
import some plugins from one workspace into another. Here's my files:
<?xml version="1.0" encoding="UTF-8"?>
<rmap
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://www.eclipse.org/buckminster/RMap-1.0"
xmlns:bc="http://www.eclipse.org/buckminster/Common-1.0"
xmlns:mp="http://www.eclipse.org/buckminster/MavenProvider-1.0"
xmlns:pp="http://www.eclipse.org/buckminster/PDEMapProvider-1.0">
<searchPath name="default">
<provider
readerType="eclipse.import"
componentTypes="eclipse.feature,osgi.bundle,buckminster,unknown "
mutable="true"
source="true">
<uri format="file:/home/test/src/eclipse?importType=linked" />
</provider>
</searchPath>
<!-- all components use the same search path -->
<locator pattern=".*" searchPathRef="default" />
</rmap>
========
<?xml version="1.0" encoding="UTF-8"?>
<cq:componentQuery xmlns:cq="http://www.eclipse.org/buckminster/CQuery-1.0"
resourceMap="file:/home/test/test-rmap.rmap">
<cq:rootRequest name="de.gebit.some.plugin"
componentType="osgi.bundle"/>
</cq:componentQuery>
Executing the query resolves the plugin just fine, popping up a wizard,
where I select "workspace" as destination type. Now whether I enter the
workspace location under "Location" or under "Workspace" (is the latter
supposed to be a workspace-relative path?) doesn't matter, the plugin is
not linked into the new workspace, but instead a plugins-folder is created
in the workspace, and the plugin is copied into that.
I.e. when I enter /tmp/ws as workspace "location" and press finish, I get
/tmp/ws/plugins/de.gebit.some.plugin/... as a result.
Not quite what I expected :-}
And when I manage to get this running (presumably with your help :-), I'll
be wondering how to do this not just with plugins, but with plain eclipse
java projects. I.e. link-import some java projects from one workspace into
another.
Thanks,
Carsten

Hi Carsten,
The "eclipse.import" reader is not designed do just any type of import. It corresponds to the two
choices you see when you right click in the Package Explorer and choose "Import" -> "Plug-in
Development", i.e. it allows you to import plug-ins and features from a target platform. We've then
extended the meaning of "target platform" to include a remote update site or a catalog like the one
used by Orbit. But you cannot import source projects using this reader.
But don't despair, there is another solution that might work for you, and that's the reader type
'local'. This reader-type was designed for the special case when Buckminster is applied on folders
that are already in existence (perhaps checked-out as part of a build that is orchestrated by
someone else). The 'local' reader will not download, nor copy anything. It will simply recognize the
presence of things.
The effect of having the 'local' reader discover source projects will be that those projects are
bound to your workspace. Nothing else will happen. This way, you can make several workspaces point
to the same set of physical files on disk.
Regards,
Thomas Hallgren
