[news.eclipse.technology.m2e] [tycho] build problem (org.eclipse.jdt.cor

[Andras Milasisn <mila@xxxxxxxxx>]

Hi!

I am currently experimenting with building Eclipse PDE components with 
Tycho. I could easily run the example and do some of my own examples as 
well. Now I want to build org.eclipse.jdt.core (checked out HEAD source 
from dev.eclipse.org:/cvsroot/eclipse CVS).

My problem is with the ant "dependency". This dependency is added using 
build.properties: 
"jars.extra.classpath=platform:/plugin/org.apache.ant/lib/ant.jar" - not 
using MANIFEST.MF. The "mvn package" command starts the process as it 
should, but the compilation fails with "The import org.apache cannot be 
resolved" error messages.

I've tried adding the ant dependency manually using dependencyManagement:

<dependency>
  <groupId>org.apache.ant</groupId>
  <artifactId>org.apache.ant</artifactId>
  <version>1.7.0</version>
  <type>eclipse-plugin</type>
</dependency>

But this doesn't help either. Can somebody help me how to add 
dependencies manually?

Regards,
  Andras.
