[tycho-user] Target Platform Definition: Could not resolve target platform specification artifact

[R***@dlr.de]

Hi,
I am trying to add target definition to my Eclipse RCP project, but the build fails with the following output:

[INFO] Scanning for projects...
[ERROR] Internal error: java.lang.RuntimeException: Could not resolve target platform specification artifact assist:ch.hilbri.assist.releng.targetplatform:target:1.0.1-SNAPSHOT -> [Help 1]
org.apache.maven.InternalErrorException: Internal error: java.lang.RuntimeException: Could not resolve target platform specification artifact assist:ch.hilbri.assist.releng.targetplatform:target:1.0.1-SNAPSHOT

I defined a target platform definition in a separate project [1]:

<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<artifactId>ch.hilbri.assist.releng.targetplatform</artifactId>
<packaging>eclipse-target-definition</packaging>
<parent>
<groupId>assist</groupId>
<artifactId>ch.hilbri.assist.releng</artifactId>
<version>2.4.0-SNAPSHOT</version>
<relativePath>../ch.hilbri.assist.releng</relativePath>
</parent>
</project>

I added this project to the main pom [2]:

...
<modules>
...
<module>../ch.hilbri.assist.releng.targetplatform</module>
...
</modules>
...
<plugin>
<groupId>org.eclipse.tycho</groupId>
<artifactId>target-platform-configuration</artifactId>
<version>${tycho.version}</version>
<configuration>
<target>
<artifact>
<groupId>assist</groupId>
<artifactId>ch.hilbri.assist.releng.targetplatform</artifactId>
<version>${project.version}</version>
</artifact>
</target>
..

Do you have an idea, what is wrong with this configuration? The entire code is available on GitHub [3]. The target platform works with Eclipse.

Thank you for any pointers...

Best,
Robert

Hi,

The error message is relatively explicit. It says it cannot find version
1.0.1-SNAPSHOT of your .target artifact, and indeed, the artifact is
actually in version 2.4.0-SNAPSHOT. You should avoid using
${project.version} to reference your eclipse-target-definition module if
the bundles that use it have different versions. As a reminder, this
${project.version} is resolved for each module, so it basically will
resolve to the version of the bundle being build, not to the version of the
pom that declares the plugin configuration.

Hi,
I changed the parent pom [1] according to your mail:

<plugin>
<groupId>org.eclipse.tycho</groupId>
<artifactId>target-platform-configuration</artifactId>
<version>${tycho.version}</version>
<configuration>
<target>
<artifact>
<groupId>assist</groupId>
<artifactId>ch.hilbri.assist.releng.targetplatform</artifactId>
<version>2.4.0-SNAPSHOT</version>
</artifact>
</target>


But the error remains:

I think this is something else
 but I have no idea, where to look :/ Any more ideas?

Best,

Hi,
I think I got it working by cleaning everything and having a fresh start on travis CI. Tycho is now picking up the target definition file properly, so this issue can be considered as being closed.
Thanks for your insights and the time you took to look into this matter.
Cheers,
Robert
