[tycho-user] Configure the output folder of assemble-repository

[Christoph Läubrich <laeubi@xxxxxxxxxxxxxx>]

I try to configure the output directory for my product build to go into 
a different folder according to [1]:

<plugin>
	<groupId>org.eclipse.tycho</groupId>
	<artifactId>tycho-p2-repository-plugin</artifactId>
	<version>${tycho.version}</version>
	<executions>
		<execution>
			<id>assemble-repository</id>
			<goals>
				<goal>assemble-repository</goal>
			</goals>
			<phase>package</phase>
			<configuration>

<repositoryLocation>${project.build.directory}/update-site-${project.artifactId}</repositoryLocation>
			</configuration>
		</execution>
	</executions>
</plugin>

but the configuration does not seem to have any effect and m2e complains 
there is no such configuration property, so it seems I'm overseen 
something but can't get whats missing here...
