Re: [tycho-user] Selective Compiling, is this possible?

[Igor Fedorenko <igor@xxxxxxxxxxxxxx>]

Although not documented, it is possible to add extra constraints to help
Tycho dependency resolver choose from alternative providers of the same
capability. Try adding configuration like below to BundleC pom.xml file


      <plugin>
        <groupId>org.eclipse.tycho</groupId>
        <artifactId>target-platform-configuration</artifactId>
        <version>${tycho-version}</version>
        <configuration>
          <dependency-resolution>
            <extraRequirements>
              <requirement>
                <type>eclipse-plugin</type>
                <id>BundleB</id>
                <versionRange>0.0.0</versionRange>
              </requirement>
            </extraRequirements>
          </dependency-resolution>
        </configuration>
      </plugin>

This will tell Tycho to resolve BundleC dependencies as if it had
"Require-Bundle: BundleB" in addition to existing Import-Package, which
will give BundleB strong preference over BundleA.

Alternatively, you can filter BundleA from BundleC target platform as
explain in [1]
