Headless Build with Tycho [message #809265] Tue, 28 February 2012 11:55 Go to next message

Hey Guys,

is there a tutorial out there which describes the headless build for an E4 Project with Tycho? I've tried some tutorials based on 3.x, but they doesn't seem to work.

Greetings Thomas

Doesn't work in what way? Building anything with tycho is simply a matter of feeding in the correct p2 repos and features.

What did you do?

The problem is maybe the folder structure, i don't know. I've created a RCP project via the Eclipse Wizard, with Application.xmi and *.product File. After that, i've created following pom inside the project:

        </plugins>
    </build>
</project>



After maven clean install, the build failed with the message:

Failed to execute goal org.eclipse.tycho:tycho-p2-director-plugin:0.14.0:materialize-products (materialize-products) on project de.test.rcp-client: Product id 'example.product' not found -> [Help 1].

But example.product is defenitly there..

Can you use the export button the .product editor to export it from within eclipse? If you can, then your best bet would be to ask on the tycho-user list, https://dev.eclipse.org/mailman/listinfo/tycho-user

Thomas, I believe Tycho is referencing the product ID from the .product's "uid" field, and not from the file name. The are two product IDs (and I'm sure PDE uses different terms internally): the product instantiation ID, which references the configuration parameters in the .product file, and the product definition ID, which references a particular extension on the org.eclipse.core.runtime.products extension point.

For an app I'm working on, we have a single product definition (i.e., one org.eclipse.core.runtime.producsts extension) but multiple .product files (with different uids) referencing that extension.

Hi Brian, great to know that somebody use e4 rcp with tycho. In my case the build for now is successful, with a custom target platform file. Unfortunately by executing the resulting exe file, the application throws an exception:

Maybe you've had this problem already an can help me. If i start the Application directly from an eclipse launch configuration, with the same dependencies like in the product file, all things are ok and the app starts.

btw. normal export via eclipse and the same target platform works fine. the plugin folder contains in both builds the same plugins.

edit2: The problem is the config.ini file. With the config.ini from the Eclipse Export, the Tycho build works. I look tomorrow deeper into this.


greetings Thomas

That's usually an indication that you haven't auto started org.eclipse.equinox.event and org.eclipse.equinox.ds.
