[tycho-user] Problem with "No primary artifact to install" in eclipse-re

[Marcus Wallin <wallmarc@xxxxxxxxx>]

I just had a long struggle with tracking down why I got the error message "No primary artifact to install, installing attached artifacts instead." from my product build (<packaging>eclipse-repository</packaging>).

Thought I would mention the cause/solution for anyone else interested.

It turns out that the parent pom had the maven-source-plugin configured:

<plugin>

    <groupId>org.apache.maven.plugins</groupId>

    <artifactId>maven-source-plugin</artifactId>

    <version>2.0.3</version>

    <inherited>true</inherited>

    <configuration>

        <outputDirectory>${project.build.directory}</outputDirectory>

        <finalName>${project.build.finalName}</finalName>

        <attach>true</attach>

    </configuration>

    <executions>

        <execution>

            <phase>package</phase>

            <goals>

                <goal>jar</goal>

            </goals>

        </execution>

    </executions>

</plugin>

Apparently, the goal "jar" seems to fork because there is also another goal "jar-no-fork".

Binding the execution to <goal>jar-no-fork</goal> in my parent pom fixes the build.

It is only speculation from my side but could it be that tycho's own forking is conflicting with maven-source-plugin and causing an extra clean to run while gathering the sources. When the maven-install-plugin is eventually executed, everything but the attached sources have been removed.

I reproduced this in tycho-demo\itp04-rcp [1] by adding the plugin configuration to itp04-rcp\eclipse-repository\pom.xml

Before I found this out the only way I could complete a build was to use "-Dclean.skip=true".
