I have looked the very good and simple example and tested it successfully (Wiki: Object_Teams_Quick-Start).
Then I wanted to compile the plugin with Tycho and read 2Between the Times" from objectteams blog.

But it didn't work.

Why didn't Tycho read the dependencies from the manifest.mf?

Before I try to reproduce I have a quick guess:
You seem to use Tycho only for binding the OT/J compiler, but your project is not actually a Tycho build because you declare a "jar" packaging.
Please try setting the packaging to s.t. like "eclipse-plugin" (see the Tycho documentation [1]).

Thanks for trying, it reminds me I should write a follow-up blog post describing how to build OT/Equinox bundles with Tycho Smile

best,
Stephan

thanks for the note, that's an error in the example. I have tried many combinations and then posted the wrong.

Maybe you have a example project, where I can look at the configuration?

maven.eclipse org/nexus or hudson.eclipse org/hudson/

You're right, the instructions in my blog are not much help for compiling OT/Equinox stuff using Tycho.
I'm working on an example and post it on my blog once I got it in a good shape,

please stay tuned,
Stephan

Alright, after some experimentation I got it to work.
I will update the parent pom and write about it in the blog but until all that is done you may try this:

Add another tweak into a pluginManagement.plugins section:

	<plugin>
		<groupId>org.eclipse.tycho</groupId>
		<artifactId>tycho-compiler-plugin</artifactId>
		<version>${tycho.version}</version>
		<extensions>true</extensions>
		<dependencies>
			<dependency>
				<groupId>org.eclipse.tycho</groupId>
				<artifactId>tycho-compiler-jdt</artifactId>
				<version>${tycho.version}</version>
				<exclusions>
					<!-- Exclude the original JDT/Core to be replaced by the OT/J variant: -->
					<exclusion>
						<groupId>org.eclipse.tycho</groupId>
						<artifactId>org.eclipse.jdt.core</artifactId>
					</exclusion>
				</exclusions>
			</dependency>
			<dependency>
				<!-- plug the OT/J compiler into the tycho-compiler-jdt plug-in: -->
				<groupId>org.eclipse</groupId>
				<artifactId>objectteams-otj-compiler</artifactId>
				<version>${otj.version}</version>
			</dependency>
		</dependencies>
	</plugin>

The difference to the existing parent pom being: now we're adapting tycho-compiler-jdt as a dependency of tycho-compiler-plugin instead of maven-compiler-plugin.

Now when you use the tycho-maven-plugin and packaging eclipse-plugin the tycho build will use the OT/J compiler.

In case that wasn't your problem, maybe you were missing a repository declaration? S.t. like:

	<repository>
		<id>Juno</id>
		<name>Eclipse Juno Repository</name>
		<url>http://download.eclipse.org/releases/juno</url>
		<layout>p2</layout>
	</repository>

With these bits I could build the OT/Equinox Quick-Start example.

HTH,
Stephan

Alright, here's the full story: http://blog.objectteams.org/2012/10/compiling-otequinox-projects-using-tycho/

And here's a shortcut to the fully configured example: http://wiki.eclipse.org/images/2/21/OTEquiTycho.zip

cheers,
