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

[Andras Milassin <mila@xxxxxxxxx>]

Hi Igor,

I've tried you're suggestion. I've added the following lines to the pom:
  <build>
    <plugins>
      <plugin>
        <groupId>org.codehaus.tycho</groupId>
        <artifactId>maven-osgi-compiler-plugin</artifactId>
        <configuration>
          <extraClasspathElements>
            <extraClasspathElement>
              <groupId>org.apache.ant</groupId>
              <artifactId>ant</artifactId>
              <version>1.7.0</version>
            </extraClasspathElement>
          </extraClasspathElements>
        </configuration>
      </plugin>
    </plugins>
  </build>


I've tried to run it, but got the following exception (it's missing the
parent pom file, it has no problem if I add ant as a dependency):

[DEBUG] Parent pom ids do not match: Parent File =
K:\DeepTest\Workspace\org.eclipse.jdt.core (head)\pom.xml, Parent ID =
dt:org.eclipse.jdt.core:3.5.0.qualifier, Child ID =
org.apache.ant:ant:1.7.0, Expected Parent ID =
org.apache.ant:ant-parent:pom:1.7.0
[ERROR]
Internal error in the plugin manager executing goal
'org.codehaus.tycho:maven-osgi-compiler-plugin:0.4.0-DEV-2233:compile':
Mojo execution failed.

Any suggestion why does it want to use the jdt.core's pom as parent?
I've tried some tricks I could come up with, but nothing helped so far.
I've tried both 0.3.0-DEV-2146 and 0.4.0-DEV-2233 releases.

Regards,
   Andras.
