Hi,

As I said in the previous message I'm working on the IAM / Buckminster
integration, and I intend to generate a CQUERY and a RMAP from a
component's pom.xml so it can be materialized by Buckminster.

I need to materialize specific versions of components and I can't always
rely on version transformations (that way it would be impossible to fully
automatize the CQUERY and RMAP generation and, at the same time, to be
sure that Buckminster finds the requested version in the corresponding
repository). So I'd like to look directly for the name of the version as
it appears in the SVN/CVS connection (for instance, in this connection
" http://svn.apache.org/repos/asf/logging/log4j/tags/v1.3alpha 8", the
version I would be looking for is "v1.3alpha8").

The CQUERY's root request would be generated by a piece of code similar to
the following:

rootRequest = new ComponentRequest( "log4j", "unknown",
"[v1.3alpha8,v1.3alpha8]", IVersionType.STRING );

And the corresponding RMAP is this one:

<rmap xmlns="http://www.eclipse.org/buckminster/RMap-1.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:bc="http://www.eclipse.org/buckminster/Common-1.0"
xmlns:mp="http://www.eclipse.org/buckminster/MavenProvider-1.0">
<searchPath name="log4j">
<provider readerType="svn" componentTypes="unknown" source="true">
<uri format="http://svn.apache.org/repos/asf/logging/log4j/trunk"/>
<versionConverter type="tag">
<transform fromPattern="^(.+)$" fromReplacement="$1"
toPattern="^(.+)$" toReplacement="$1"/>
</versionConverter>
</provider>
</searchPath>
<locator searchPathRef="log4j" pattern="log4j"/>
</rmap>

Of course, I won't be writing this message if everything was ok :-) This
is Buckminster's debug output when I execute the query:

log4j:unknown/[v1.3alpha8,v1.3alpha8]#String: Using resolver rmap
Downloading file:/home/isma/dev/xxx/foo.rmap
log4j:unknown/[v1.3alpha8,v1.3alpha8]#String: Using resource map

match was found
Attempt to use an unresolved node. Request is
log4j:unknown/[v1.3alpha8,v1.3alpha8]#String

I supposed I've missed some important point when I read the documentation,
but I just can't see it... Oh, the tag I'm looking for in this example is
here indeed: http://svn.apache.org/repos/asf/logging/log4j/tags/v1.3alpha 8/

Thanks in advance for your help!

Hi Ismael,
The VersionConverter will attempt to create versions of type OSGi if nothing else is
specified. In this case, try using

<versionConverter type="tag" versionType="String">
<transform fromPattern="^(.+)$" fromReplacement="$1" toPattern="^(.+)$"
toReplacement="$1"/>
</versionConverter>

You may wish to use Triplet instead of String. The Triplet parser should be able to
understand a version like 1.3alpha8 and will give you better magnitude comparisons then
the String version. You will need to alter the to/from patterns slightly to accommodate this:

<versionConverter type="tag" versionType="Triplet">
<transform fromPattern="^v(.+)$" fromReplacement="$1" toPattern="^(.+)$"
toReplacement="v$1"/>
</versionConverter>

rootRequest = new ComponentRequest( "log4j", "unknown", "[1.3alpha8,1.3alpha8]",
IVersionType.TRIPLET);

Regards,
Thomas Hallgren
