如何使用Tycho使用Maven将Java项目构建为OSGi部署软件包？

Question

I have some Java/OSGi projects that I wish to build and package as a single Deployment Package.

I'm using Tycho to compile the sources for a particular target-platform, all dependencies are in a local p2 repository.

If I set <packaging>eclipse-plugin</packaging> in my pom.xml the build goes fine but I get a .jar as output.
When I use maven-bundle-plugin and set <packaging>bundle</packaging> the build breaks, because it compiles with the standard maven-compiler-plugin instead of Tycho.

<plugin>
    <groupId>org.apache.felix</groupId>
    <artifactId>maven-bundle-plugin</artifactId>
    <version>2.3.5</version>
    <extensions>true</extensions>
    <configuration>
        <manifestLocation>META-INF</manifestLocation>
        <instructions>
            <Bundle-SymbolicName>${project.artifactId};singleton:=true</Bundle-SymbolicName>
            <Bundle-Name>${project.name}</Bundle-Name>
            <Bundle-Version>${project.version}</Bundle-Version>
            <Import-Package>
                javax.net;resolution:=optional,
                javax.net.ssl;resolution:=optional
            </Import-Package>
            <Export-Package>my.project.package</Export-Package>
        </instructions>
    </configuration>
</plugin>

How do I force the compilation with Tycho? Or is there any other way to do what I need?

That answer may come a bit late, but I recently created a Maven plugin "de.dentrassi.maven:osgi-dp" which can create those "DP"s.

See: https://ctron.github.io/osgi-dp/plugin-info.html

You can either create a specialized "dp" packaging or re-use Eclipse Tycho's feature metadata:

<plugin>
    <groupId>de.dentrassi.maven</groupId>
    <artifactId>osgi-dp</artifactId>
    <executions>
        <execution>
            <goals>
                <goal>build</goal>
            </goals>
        </execution>
    </executions>
</plugin>

For a full example of using Tycho for compiling and "osgi-dp" for creating the deployment package see the integration test at GitHub .
