[tycho-user] Tycho build feature with maven repository

[Ismael Soulama]

Hi,
I'm trying to build an Eclipse feature with tycho.
But in my feature, I have a plugin deployed in a maven repository.
In my pom.xml, I use:
[code]...
<dependencyManagement>
<dependency>
<groupId>my.plugin</groupId>
<artifactId>my.plugin</artifactId>
<version>${my.plugin.version}</version>
</dependency>
<dependency>
<groupId>my.plugin</groupId>
<artifactId>my.plugin</artifactId>
<version>${my.plugin.version}</version>
<classifier>p2metadata</classifier>
<type>xml</type>
</dependency>
<dependency>
<groupId>my.plugin</groupId>
<artifactId>my.plugin</artifactId>
<version>${my.plugin.version}</version>
<classifier>p2artifacts</classifier>
<type>xml</type>
</dependency>
</dependencyManagement>
<plugin>
<groupId>org.eclipse.tycho</groupId>
<artifactId>target-platform-configuration</artifactId>
<configuration>
<pomDependencies>consider</pomDependencies>
</configuration>
</plugin>
...[/code]

But the build failes with:
