xtext P2 referencing specific version with P2 reader. [message #1015057]

Eclipse User

Hello,

I am trying to import a specific version from the Xtext update site with
this .rmap entry:

<rm:searchPath name="org.eclipse.xtext">
<rm:provider componentTypes="buckminster,osgi.bundle,eclipse.feature"
readerType="p2" source="false" mutable="false">
<rm:property key="buckminster.source" value="false" />
<rm:property key="buckminster.mutable" value="false" />
<rm:uri

format="http://download.eclipse.org/modeling/tmf/xtext/updates/composite/releases/{0}">
<bc:propertyRef key="xtext.version" />
</rm:uri>
</rm:provider>
</rm:searchPath>

Unfortunnately this doesn't work, as I can't simply concat the version
behind the uri fragment /releases/. How do I reference a specific
category in the p2 update site? I have tried with setting the
xtext.version to "TMF 20Xtext-2.0.1" with no success. (I can see this
category exists when trying the update site in the Eclipse IDE).

This is bucky's error:

ERROR [0019] : No suitable provider for component
org.eclipse.xtext:osgi.bundle was found in searchPath org.eclipse.xtext
ERROR [0019] : Rejecting provider
p2(http://download.eclipse.org/modeling/tmf/xtext/updates/composite/releases/{0}[http://download.eclipse.org/modeling/tmf/xtext/updates/composite/releases/TMF
Xtext-2.0.1]): No component match was found
ERROR No repository found at
http://download.eclipse.org/modeling/tmf/xtext/updates/composite/releases/TMF%20Xtext-2.0.1/.

Thank You ! Christophe

Although I've never done that myself, I think you should specify a
version range in the cquery...

ERROR No repository found at
http://download.eclipse.org/modeling/tmf/xtext/updates/composite/releases/TMF%20Xtext-2.0.1/

You can't navigate through the composite repository by using an update site category label "TMF Xtext-2.0.1".

Xtext 2.0.1 repository is located here: http://download.eclipse.org/modeling/tmf/xtext/updates/releases/head/R201108020636/

If you would like to use the composite one, you have to use a version constraint in your cquery, like Lorenzo has suggested. Or put a version constraint in your feature. Buckminster will grab the right one.

Thanks! I just wonder where this URL is published on the web. I can't
find it in the Xtext download section here:

http://www.eclipse.org/modeling/tmf/downloads/?project=xtext

OK, will try this!

Hi,

I have been looking how, I can add a version constraint in a cquery, but
I don't see where and how this is done. Can someone please explain?

If it's done through an advisor node, which section should I use?
Is it the filter in the General section? If it's override, it seems this
is really to change the version in the materialized component right?

thank you, Christophe

Normally I use the constraints in my buckminster CSPEC

<cs:cspec xmlns:cs="http://www.eclipse.org/buckminster/CSpec-1.0" name="org.eclipse.xtext.releng" componentType="buckminster" version="1.0.0.qualifier">
    <cs:dependencies>
        <cs:dependency name="com.google.guava" componentType="osgi.bundle" versionDesignator="[10.0.0,12.0.0)"/>

Sometimes it's necessary to override version cotraint in the cquery:

    <cq:advisorNode namePattern="org.eclipse.emf.ecore.editor" componentType="osgi.bundle" useTargetPlatform="false" versionOverride="[2.5.0,2.6.0)"/>

Thanks Dennis. Does it mean you create your own cspec? (As these would
be generated normally when using a feature containing all dependencies).

Yes, I have an own CSPEC for my releng project in order to set up the target platform first.
However, you can also use your "main/build" feature to define constraints e.g

   <requires>
      <import feature="org.eclipse.xtend.sdk" version="2.4.0" match="equivalent"/>
      <import plugin="org.eclipse.emf.ecore" version="2.5.0" match="greaterOrEqual"/>
      <import plugin="org.eclipse.emf.common" version="2.5.0" match="greaterOrEqual"/>
      <import plugin="org.eclipse.emf.ecore.source" version="2.5.0" match="greaterOrEqual"/>
      <import plugin="org.eclipse.emf.common.source" version="2.5.0" match="greaterOrEqual"/>
   </requires>

Buckminster will take care that this contraints are fulfilled.

Tried this, unfortunately it still drags in the latest release of Xtext
(2.3.1).

Then I also tried with the cquery override, and the provider gets rejected.

ERROR [0022] : No suitable provider for component
org.eclipse.xtext:osgi.bundle/[2.0.0,2.0.1] was found in searchPath local
ERROR [0022] : Resolution attempt ended with exception: Provider
local(/var/lib/jenkins/workspace/netxstudio.git.p2/org.eclipse.xtext):
Missing CSpec source required by component type osgi.bundle

.....further on the provder rejection with the URL you gave me. (I
checked in Eclipse and it looks OK).

ERROR [0022] : Rejecting provider

No component match was found

Here is my cquery definition:

<cq:advisorNode namePattern="^org\.eclipse\.xtext\.*"
componentType="osgi.bundle" versionOverride="[2.0.0,2.0.1]">
<cq:documentation xmlns="http://www.w3.org/1999/xhtml">Version
requirements on Xtext</cq:documentation>
</cq:advisorNode>

What am I doing wrong?

Could you please post how your build feature looks like? And the rmap?

And the cquery pattern would only match bundles named org.eclipse.xtext(many dots)

Try this: <cq:advisorNode namePattern="^org\.eclipse\.xtext.*" versionOverride="[2.0.0,2.0.2)">

I widened the version range, to 2.2.0 and it works now!

Hi

I'm resuming this thread for a similar question:

I tried to put in my main feature this

<requires>
<import feature="org.eclipse.xtext.sdk" version="2.3.1" match="equivalent"/>
</requires>

which should be equivalent to [2.3.1,2.4.0)

however, the materialization still drags in Xtext 2.4.0...

can it be because I also have a dependency on org.eclipse.xtext.sdk in
my main cspec (without any version designator)?

thanks in advance
Lorenzo
