---------------------------------------
Summary: Support system-properties in extension.xml
Key: MNG-7395
URL: https://issues.apache.org/jira/browse/MNG-7395
Project: Maven
Issue Type: Improvement
Reporter: Christoph Läubrich
Currently an entry has to be the following form:
{code:xml}
<extension>
<groupId>org.eclipse.tycho</groupId>
<artifactId>tycho-build</artifactId>
<version>2.7.0-SNAPSHOT</version>
</extension>
{code}
This has the drawback that I always need to edit the extension.xml file and
there is no way to specify it on the commandline.
The proposal is to allow the follwoing:
{code:xml}
<extension>
<groupId>org.eclipse.tycho</groupId>
<artifactId>tycho-build</artifactId>
<version>${tycho-version|2.6.0}</version>
</extension>
{code}
I would then expect the following:
# If no systemproperty with name 'tycho-version' exits, the value after the |
is used as a default
# If a systemproperty with name 'tycho-version' exits it is used as a version
That way I can call mvn -Dtycho-version=2.7.0-SNAPSHOT clean install to
override the default version.
