m2e shade eclipse "project main artifact does not exist"

I'm trying to make a deployment package that bundles all the dependencies of my maven module that has dependencies to another maven project in eclipse.

I have this in my pom.xml

<modelVersion>4.0.0</modelVersion>
<groupId>com.my.proj</groupId>
<artifactId>AAA</artifactId>
<version>0.0.2-SNAPSHOT</version>
<name>btc</name>
<dependencies>
    <dependency>
        <groupId>com.another.proj</groupId>
        <artifactId>BBB</artifactId>
        <version>1.4-SNAPSHOT</version>
    </dependency>
</dependencies>

<build>
    <plugins>

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-shade-plugin</artifactId>
            <version>1.6</version>
            <executions>
                <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>shade</goal>
                    </goals>
                    <configuration>
                        <transformers>
                            <transformer
                                implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                                <mainClass>com.group.id.Launcher1</mainClass>
                            </transformer>
                        </transformers>
                    </configuration>
                </execution>
            </executions>
        </plugin>

    </plugins>
</build>

I use that "m2 Maven Build" in eclipse with the goal "org.apache.maven.plugins:maven-shade-plugin:shade" and the "Resolve Workspace artifacts" ticked.

It's failing with
