Hi,

We are building a RCP app with multiple DSLs. Our application rely on p2 to download update of the application.

Unfortunately xtext plugins which are obviously added to our product, contribute to the available software sites by adding Xtext All In One - Releases update site. This is done in org.eclipse.xtext-2.4.1\features\org.eclipse.xtext.runtime.feature\p2.inf:

instructions.configure=org.eclipse.equinox.p2.touchpoint.eclipse.addRepository(location:http${#58}//download.eclipse.org/ modeling/tmf/xtext/updates/composite/releases/,type:0,name:Xtext All In One - Releases,enabled:true); \
  org.eclipse.equinox.p2.touchpoint.eclipse.addRepository(location:http${#58}//download.eclipse.org/ modeling/tmf/xtext/updates/composite/releases/,type:1,name:Xtext All In One - Releases,enabled:true);

That means when the user launch a check for update, it will also check if xtext update are available.

So my question is more a p2 related issue: how can we remove this contribution (or how to disable it) ?

What I've tried so far was add instruction in some p2.inf of our plugin to remove the xtext contribution, like

instructions.configure=\
removeRepository(location:http${#58}//download.eclipse.org/modeling/tmf/xtext/updates/composite/releases/,type:0);\
removeRepository(location:http${#58}//download.eclipse.org/modeling/tmf/xtext/updates/composite/releases/,type:1);

but it doesn't work...

Thanks for your help,
Yann
PS: A workaround could be to fix the "Maximum version" of our dependency to xtext.

Try

instructions.configure=org.eclipse.equinox.p2.touchpoint.eclipse.addRepository(location:http${#58}//download.eclipse.org/ modeling/tmf/xtext/updates/composite/releases/,type:0,name:Xtext All In One - Releases,enabled:false); \
  org.eclipse.equinox.p2.touchpoint.eclipse.addRepository(location:http${#58}//download.eclipse.org/ modeling/tmf/xtext/updates/composite/releases/,type:1,name:Xtext All In One - Releases,enabled:false);

Or...

instructions.configure=\
org.eclipse.equinox.p2.touchpoint.eclipse.removeRepository(type:0,location:http${#58}//download.eclipse.org/ modeling/tmf/xtext/updates/composite/releases/);\
org.eclipse.equinox.p2.touchpoint.eclipse.removeRepository(type:1,location:http${#58}//download.eclipse.org/ modeling/tmf/xtext/updates/composite/releases/);

Hello Dennis,

this does not work in all cases (seems to be a matter of execution order). do you have any other ideas?

Thanks, Christian

If your RCP feature depends on Xtext, there can be only one installation order, or what do you mean with execution order?

Hi,

i have no idea how eclipse analyzes the touchpoints. thus it may depend on the order of the information beeing analyzed.
the addRepositository we do in the same p2.inf like the removeRepository work.
the p2.inf is besides the product file.
we build with Maven Tycho 0.20.0

I also know only what described in the eclipse help, and it works like described in previous comments using buckminster or PDE

http://help.eclipse.org/kepler/index.jsp?topic=%2Forg.eclipse.platform.doc.isv%2Fguide%2Fp2_actions_touchpoints.html

Tycho should handle this in the same order, it use p2 to create products.
What you can try is to put your p2.inf in a bundle (META-INF/p2.inf) where you are sure, it is logically installed/configured at the most last moment. Also p2 tracing may help to figure out what exactly happens during the tycho product build.
