Re: [tycho-user] "eclipse-feature" Maven dependency to target-platform-c

[Julien DEHAUDT <julien.dehaudt@xxxxxx>]

Oups, just to correct my previous mail.

 

Of course in 1) <distributionManagement> is used for deployment.

I copied the wrong pom.xml section, it should be:

 

<repositories>

      <repository>

            <id>third-party-components</id>

            <name>Third Party Components</name>

            <url>https://somewhere.in.the.company</url>

      </repository>

</repositories>

 

Thanks,

Julien

Subject: "eclipse-feature" Maven dependency to target-platform-configuration

 

Hi,

 

First of all thanks for the 1.1.0 release, I used the snapshot version for a while, since it integrates the zip comparator for baselines.

 

Today I am stuck with the way to integrate a dependency into the target platform.

Some components I must integrate into my Eclipse RCP are published on a Maven repository.

For sure just a basic use-case, but no way to get it working.

 

Hereafter what I tried:

 

1) Declare the 3-PP Maven repository (root parent pom.xml)

<distributionManagement>

      <repository>

            <id>central</id>

            <name>releases</name>

            <url>https://somewhere.in.the.company</url>

      </repository>

</distributionManagement>

 

2) Define the dependencies; the feature and its plugin built which Tycho/pomless too (root parent pom.xml):

<dependencies>

      <dependency>

            <type>eclipse-feature</type>

            <groupId>some.component.tycho</groupId>

            <artifactId>some.component.feature</artifactId>

            <version>1.0.0-SNAPSHOT</version>

      </dependency>

      <dependency>

            <type>eclipse-plugin</type>

            <groupId>some.component.tycho</groupId>

            <artifactId>some.component.plugin</artifactId>

            <version>1.0.0-SNAPSHOT</version>

      </dependency>

</dependencies>

 

3) Configure the target platform (root parent pom.xml):

<plugin>

      <groupId>org.eclipse.tycho</groupId>

      <artifactId>target-platform-configuration</artifactId>

      <version>${tycho.version}</version>

      <configuration>

            ...

            <pomDependencies>consider</pomDependencies>

            <dependency-resolution>

                  <extraRequirements>

                        <requirement>

                              <type>eclipse-plugin</type>

                              <id>some.component.plugin</id>

                              <versionRange>0.0.0</versionRange>

                        </requirement>

                  </extraRequirements>

                  <extraRequirements>

                        <requirement>

                              <type>eclipse-feature</type>

                              <id>some.component.feature</id>

                              <versionRange>0.0.0</versionRange>

                        </requirement>

                  </extraRequirements>

            </dependency-resolution>

      </configuration>

</plugin>

 

 

But “mvn -X clean verify -Dtycho.debug.resolver=true” fails with the following error:

[DEBUG] No solution found because the problem is unsatisfiable.: [Unable to satisfy dependency from tycho-extra-1518083760116 0.0.0.1518083760116 to some.component.feature.feature.group 0.0.0.; Unable to satisfy dependency from tycho-1518083760157 0.0.0.1518083760157 to some.component.feature.feature.group 0.0.0.; No solution found because the problem is unsatisfiable.]

[ERROR] Cannot resolve project dependencies:

[ERROR]   You requested to install 'some.component.feature.feature.group 0.0.0' but it could not be found

 

 

Analyzing the whole log and my .m2/repository highlight that both Maven dependencies are well downloaded from the repository.

Anyway only the plugin looks managed by target-platform-configuration plugin, and something get wrong with the feature.

Does someone have any suggestion helping to progress ?

I’m completely stuck with this “feature not found” issue.

 

Thanks.
