[tycho-user] restricting target platform environments.

[Barrie Treloar <baerrach@xxxxxxxxx>]

My target platform is failing to resolve environments that I don't care about:

[ERROR] Internal error: java.lang.RuntimeException: Failed to resolve

I've already tried restricting the platform via configuration with

      <plugin>
        <groupId>org.eclipse.tycho</groupId>
        <artifactId>target-platform-configuration</artifactId>
        <version>${tycho-version}</version>
        <configuration>
          <resolver>p2</resolver>
          <dependency-resolution>
            <optionalDependencies>ignore</optionalDependencies>
          </dependency-resolution>
          <target>
            <artifact>
              <groupId>mygroup</groupId>
              <artifactId>mytarget</artifactId>
              <version>${project.version}</version>
              <classifier>XXXX</classifier>
            </artifact>
          </target>
          <ignoreTychoRepositories>true</ignoreTychoRepositories>
          <environments>
            <environment>
              <os>win32</os>
              <ws>win32</ws>
              <arch>x86</arch>
            </environment>
          </environments>
        </configuration>
      </plugin>

And by adding to the target file:
<environment>
<os>win32</os>
<ws>win32</ws>
<arch>x86</arch>
</environment>

I'd care less if these artifacts were actually available, except my
build times increase unnecessarily.
Running
  java -jar D:\eclipse-3.7.2\plugins\org.eclipse.equinox.launcher_1.2.0.v20110502.jar
 -debug  -console log -nosplash -application
org.eclipse.equinox.p2.director -repository
http://download.eclipse.org/releases/indigio/  -list
(and again on galileo and helios) shows that ppc has is only available
in galileo, its ppc64 in indigo and helios

What did I miss with the restricting of environments?

Thanks
