Hi Matthias,

I have a use case in which a plug-in project (PDE) needs to be build using maven.

I am following these steps:

———————————————————————–
1. Created a simple plug-in project

2. Ran following command to generate pom.xml :
mvn org.sonatype.tycho:maven-tycho-plugin:generate-poms -DgroupId=tychodemo.grp -Dtycho.targetPlatform=C:/Work/IDEs/eclipse-jpaas-indogo-sr1-win64/

Build success. Pom created using the above command.

3. Ran following command for installation:
mvn clean install

Build Failed, [ERROR] Unknown packaging: eclipse-plugin @ line 8, column 14 : Added Tycho related build in pom.xml (manually)
This manual add was required since eclipse-plugin is not known to maven, and tycho being an extension of maven knows about it.

0.13.0

org.eclipse.tycho
tycho-maven-plugin
${tycho-version}
true

Using reference : http://wiki.eclipse.org/Tycho/Reference_Card

4. Ran following command :
mvn clean install -Dtycho.targetPlatform=C:/Work/IDEs/eclipse-jpaas-indogo-sr1-win64/

Build Success.

—————————————————————-
Now the build is done, is there a possibility I can eliminate the manual step of adding tycho related tags in
pom.xml as in step 3 above, and the complete build is achieved by just commands?

Please let me know if you need more information.

Any help is appreciated.

Thanks & Regards,
Piyush

Hi Matthias

I have a bundle project which references (through Manifest “Require-Bundle”) other OSGi bundles I have developed. Building with Tycho I’m getting a P2 error like

“… requires ‘bundle one.of.my.bundles 1.0.0′ but it could not be found” … org.eclipse.equinox.p2.core.ProvisionException

My bundles exist in the local Maven repo. Is there a way for having Tycho resolve bundle dependencies it finds in “Require-Bundle”, by first looking into my local Maven repository first?

Hi Mattias,

thanks for this excellent series of articles; this was really useful when we started out.

We’re writing a series on some “real world issues” when moving existing products to Tycho and TeamCity, hopefully to repay the favour and help somebody else!

Hi mattias,
Thanks for the article. I followed the steps that you have mentioned in the article and could able to build a plugin.
Later I tried to extend it by defining CLASSPATH VARIABLE in Java build path as M2_REPO. I added a log4j library using the M2_REPO variable and tried compiling the project using same steps defined above. But this time, I got compilation error and it seems maven-osgi-compiler-plugin is not referring to the M2_REPO classpath variable. I am stuck here and not able to proceed, can you please tell me where I am going wrong?

I actually never tried this on Maven 3, but if you ask the people at the Tycho mailing list, I bet they’ll know what differs between Maven 2 and Maven 3. If it’s not that important for you to use Maven 3, try using a release of Maven 2 to follow this tutorial. Good luck!

Hi,

is it possible to define the tycho.targetPlatform not as parameter or property? I would like to define the target platform in the pom.xml pointing to 2 directories (eclipse and delta pack for instance or to eclipse and rap runtime).

Regards,
Oliver

> Unknown packaging: eclipse-plugin
If you get this error message you are propably using the wrong version of Maven. The version you can download from Apache isn’t built with tycho support.
You’ll need to install a version of Sonatype (http://repository.sonatype.org/content/repositories/tycho-pseudo-releases/org/codehaus/tycho/tycho-distribution/).

Version Camparison shows:
From Apache: Apache Maven 3.0.2 (r1056850; 2011-01-09 01:58:10+0100)
From Sonatype: Apache Maven 3.0-TYCHO-818442 (r818615; 2009-09-24 23:00:12+0200)
