Hi,

I wonder if I can "wrap" a CQuery in another CQuery like this:

<cq:componentQuery xmlns:cq="http://www.eclipse.org/buckminster/CQuery-1.0" resourceMap="local.cquery">
<cq:advisorNode namePattern="org\.eclipse\..*\.source" skipComponent="true"/>
</cq:componentQuery>

Obviously not. The build produces this exception:

[java] java.lang.NullPointerException

I guess this is not something that's supposed to work somehow?

Is there another way to suppress the materialization of source plugins conditionally (e.g. in a remote build as opposed to a local workspace setup)?

Cheers

No. You can nest rmaps (by using redirects) but not cqueries.

The property buckminster.download.source controls automatic download of sources. It is set to true by default when you
run in the IDE and false when you run headless. It will however not affect explicitly declared dependencies to source
bundles. In order to override them in different ways, you'll need to use two different cquery files.
