Re: [tycho-user] Question on Maven/Tycho target mechanism using .target file

classifier is optional (and no longer needed if you use packaging type eclipse-target-definition [1])

Disclaimer: I am a tycho newbie .

I think you need to add a classifier tag.  Also be sure that the artifactId tag has the name of the project that contains the target file specified in the <classifier>.  I do not have a <relativePath> tag at all in the config element.
<artifact>
                <groupId>com.etas.congra.releng</groupId>
                <artifactId>com.etas.congra.releng.targetplatform</artifactId>
                <relativePath>../../releng/com.etas.congra.releng.targetplatform/pom.xml</relativePath>
               <classifier>unqualified file name of target file</classifier>
            </artifact>

Subject: [tycho-user] Question on Maven/Tycho target mechanism using .target file

Hello all,

I have a problem with the Maven/Tycho mechanism to resolve a .target file. I followed the information on https://wiki.eclipse.org/Tycho/Target_Platform#Target_files, but do not get the expected results. Here are some facts:

Target file:

<target name="Eclipse Kepler Target" sequenceNumber="1424335573">
<locations>
    <location includeMode="slicer" includeAllPlatforms="false" includeSource="false" includeConfigurePhase="false" type="InstallableUnit">
        <unit id="org.eclipse.sdk.feature.group" version="0.0.0"/>
        <unit id="org.eclipse.equinox.executable.feature.group" version="0.0.0"/>
        <unit id="org.eclipse.equinox.p2.sdk.feature.group"  version="0.0.0"/>
        .
        <repository id="kepler" location="http://korvm016.apac.bosch.com/updatesites/thirdparty/eclipse_4.3_kepler/"/>
    </location>
    <location includeMode="slicer" includeAllPlatforms="false" includeSource="false" includeConfigurePhase="false" type="InstallableUnit">
        <unit id="ch.qos.logback.classic" version="0.0.0"/>
        <unit id="ch.qos.logback.classic.source" version="0.0.0"/>
        <unit id="ch.qos.logback.core" version="0.0.0"/>
        <unit id="ch.qos.logback.core.source" version="0.0.0"/>
        <unit id="ch.qos.logback.slf4j" version="0.0.0"/>
        <unit id="ch.qos.logback.slf4j.source" version="0.0.0"/>
        <unit id="org.slf4j.api" version="0.0.0"/>
        <unit id="org.slf4j.api.source" version="0.0.0"/>
        ..
        <repository id="orbit" location="http://korvm016.apac.bosch.com/updatesites/thirdparty/orbit-buildrepo-R20140525021250/"/>
     </location>
    ..
</locations>
</target>

The pom-File for the target module:

<?xml version="1.0" encoding="UTF-8"?>
<project
       xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd&quot;
       xmlns="http://maven.apache.org/POM/4.0.0&quot; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance&quot;>
       <modelVersion>4.0.0</modelVersion>
       <parent>
        <groupId>com.etas.congra.releng</groupId>
        <artifactId>com.etas.congra.releng.parent</artifactId>
        <version>0.1.0-SNAPSHOT</version>
        <relativePath>../../releng/com.etas.congra.releng.parent/pom.xml</relativePath>
       </parent>
       <groupId>com.etas.congra.releng</groupId>
       <artifactId>com.etas.congra.releng.targetplatform</artifactId>
       <packaging>eclipse-target-definition</packaging>
</project>

I do not have a version in here, because I found a page in the web which told the story that a version in the pom for the eclipse-target-packaging does not work and in fact, specifying a version resulted in not resolving the following configuration in the parent pom used for all other maven modules:

<plugins>
<plugin>
    <groupId>org.eclipse.tycho</groupId>
    <artifactId>target-platform-configuration</artifactId>
    <version>${tycho-version}</version>
    <configuration>
        <target>
            <artifact>
                <groupId>com.etas.congra.releng</groupId>
                <artifactId>com.etas.congra.releng.targetplatform</artifactId>
                <relativePath>../../releng/com.etas.congra.releng.targetplatform/pom.xml</relativePath>
            </artifact>
        </target>
    </configuration>
</plugin>
</plugins>

With this in place I get the following error message during the maven build:

[INFO] Scanning for projects...
[INFO] Computing target platform for MavenProject: com.etas.congra.releng:com.etas.congra.log:0.1.0-SNAPSHOT @ D:\ConGra_IDE_Luna_win64\git\congra\plugins\com.etas.congra.log\pom.xml

[ERROR]

It cannot resolve dependencies from the target, although the target works properly in the eclipse workspace and if all repositories mentioned in the target files are expressed as repository tags in the pom file, the build works.

Has anybody an idea what is wrong in my configuration?

Thanks and best regards,
Lars
