tycho-p2-director-plugin deletes generated artifacts

Question

I am trying to use tycho-p2-director-plugin in order to materialize a product but the plugin seems to delete the artifacts near the execution end. Moreover the line up of the plugins called is weird: "tycho-p2-repository-plugin" --> "tycho-packaging-plugin" --> "maven-clean-plugin" --> "tycho-p2-director-plugin".

Following is the pom.xml of the product project:

...
<packaging>eclipse-repository</packaging>

<build>
    <plugins>
        <plugin>
            <groupId>org.eclipse.tycho</groupId>
            <artifactId>tycho-p2-director-plugin</artifactId>
            <version>0.24.0</version>
            <executions>
                <execution>
                    <id>materialize-products</id>
                    <goals>
                        <goal>materialize-products</goal>
                    </goals>
                </execution>
            </executions>
                <configuration>
                    <products>
                        <product>
                            <id>productSample</id>
                        </product>
                    </products>
                </configuration>
        </plugin>       
    </plugins>
</build>

Following is the output of invoking "mvn package" on the product project:

It's apparent the tycho-p2-director-plugin will not find any files since maven-clean-plugin was somehow called after tycho-packaging-plugin! Any ideas why this is happening?

there is a maven clean plugin in the default lifecycle [1] of eclipse-repository, but it's mapped to lifecycle phase 'initialize' by default.

the clean invocation with id 'default-clean-1' in your build log seems strange to me.

This could be caused by a forked maven lifecycle. The maven-source-plugin may be responsible for this (at least I would not expect a maven-source-plugin execution when building an eclipse-repository packaging type)

Looks like [2] is related. Try to either remove maven-source-plugin or if you really need it, try using its jar-no-fork goal instead.

[2] Difference between Maven source plugin jar and jar-no-fork goal?
