Unable to build a POM-less OSGi bundle with tycho - maven

Question

I've a "Hello, World!" OSGi bundle based on the tycho's 0.24 POM-less build example. The project root includes a directory with the bundle code named com.softalks.tycho.bundle and the following build configuration files
.mvn/extensions.xml
<?xml version="1.0" encoding="UTF-8"?>
<extensions>
<extension>
<groupId>org.eclipse.tycho.extras</groupId>
<artifactId>tycho-pomless</artifactId>
<version>0.24.0</version>
</extension>
</extensions>
pom.xml
<?xml version="1.0" encoding="UTF-8"?>
<project>
<modelVersion>4.0.0</modelVersion>
<groupId>com.softalks.tycho</groupId>
<artifactId>com.softalks.tycho.parent</artifactId>
<version>1.0.0-SNAPSHOT</version>
<packaging>pom</packaging>
<repositories>
<repository>
<id>luna</id>
<url>http://download.eclipse.org/releases/luna</url>
<layout>p2</layout>
</repository>
</repositories>
<modules>
<module>com.softalks.tycho.bundle</module>
</modules>
<build>
<plugins>
<plugin>
<groupId>org.eclipse.tycho</groupId>
<artifactId>tycho-maven-plugin</artifactId>
<version>0.24.0</version>
<extensions>true</extensions>
</plugin>
</plugins>
</build>
</project>
My build environment:
Apache Maven 3.3.9
Java version: 1.7.0_95, vendor: Oracle Corporation
Java home: /usr/lib/jvm/java-7-openjdk-amd64/jre
OS name: "linux", version: "3.13.0-61-generic", arch: "amd64", family: "unix"
And the Maven response:
Child module /home/runner/tycho/com.softalks.tycho.bundle/pom.xml of /home/runner/tycho/pom.xml does not exist
I've also tried to add this to my pom (as the example does) with no success:
<pluginRepositories>
<pluginRepository>
<id>tycho-snapshots</id>
<url>https://repo.eclipse.org/content/repositories/tycho-snapshots/</url>
<releases>
<enabled>true</enabled>
</releases>
<snapshots>
<enabled>true</enabled>
</snapshots>
</pluginRepository>
</pluginRepositories>
What am I doing wrong?

You have to provide a pom.xml in your /home/runner/tycho/com.softalks.tycho.bundle/ directory. And yes 'pomless' but the parent pom in this directory has to be written.
<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/maven-v4_0_0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.softalks.tycho</groupId>
<artifactId>bundles</artifactId>
<version>1.0.0-SNAPSHOT</version>
<packaging>pom</packaging>
<parent>
<groupId>com.softalks.tycho</groupId>
<artifactId>com.softalks.tycho.parent</artifactId>
<version>1.0.0-SNAPSHOT</version>
</parent>
<modules>
<module>...All your modules...</module>
</modules>
</project>
All the pom.xml files in the modules directories mentioned here will be generated automatically.
