I'm using tycho to automatically build my RCP application (actually, I've adopted the structure reported in one of the examples). I have to say that it works very well and I'm able to support all the three architectures I need (linux x86, linux x86_64, win32 x86).
Additionally, part of the application requires some native code, which I provide with fragments (see my previous question). Each fragment is tailored for a particular architecture, hence specify it in the fragment's MANIFEST:
Eclipse-PlatformFilter: (& (osgi.os=linux) (osgi.arch=x86_64))
However, if I run mvn install I obtain:
[ERROR] Internal error: java.lang.RuntimeException: "Problems resolving provisioning plan.": ["tycho.jni.linux 1.0.0.qualifier cannot be installed in this environment because its filter is not applicable."] -> [Help 1]

Note that the same project without the Eclipse-PlatformFilter compiles correctly... what I'm missing?
Try narrowing down the environments of your fragment's pom.xml to just the one matching the Eclipse-PlatformFilter:
<build>
<plugins>
<plugin>
<groupId>org.eclipse.tycho</groupId>
<artifactId>target-platform-configuration</artifactId>
<version>${tycho-version}</version>
<configuration>
<environments>
<environment>
<os>linux</os>
<ws>gtk</ws>
<arch>x86_64</arch>
</environment>
</environments>
</configuration>
</plugin>
</plugins>
</build>
