Calling generator from CLI in offline mode does not work

[UdoW]

I call the generator via a Maven script with the Tycho Eclipse Run plug-in like this:

<build>
	<plugins>
		<plugin>
			<groupId>org.eclipse.tycho.extras</groupId>
			<artifactId>tycho-eclipserun-plugin</artifactId>
			<version>2.7.2</version>
			<configuration>
				<repositories>
					<repository>
						<id>2022-03</id>
						<layout>p2</layout>
					<url>file:///${rootDir}/p2/platform/2022-03/target/repository</url>
					</repository>
					<repository>
						<id>targetplatform</id>
						<layout>p2</layout>
						<url>file:///${rootDir}/p2/cbi/target/repository</url>
					</repository>
				</repositories>
				<applicationsArgs>
					<args>-consoleLog</args>
					<args>-application</args>
					<args>org.eclipse.cbi.targetplatform.tpd.converter</args>
					<args>mytarget.targetplatform</args>
				</applicationsArgs>
				<executionEnvironment>JavaSE-11</executionEnvironment>
				<!-- Set dependencies to launch the application -->
				<dependencies>
					<dependency>
						<artifactId>org.eclipse.cbi.targetplatform.feature</artifactId>
						<type>eclipse-feature</type>
					</dependency>
					<dependency>
						<artifactId>org.eclipse.equinox.p2.sdk</artifactId>
						<type>eclipse-feature</type>
					</dependency>
					<dependency>
						<artifactId>org.slf4j.api</artifactId>
						<type>eclipse-plugin</type>
					</dependency>
					<dependency>
						<artifactId>org.eclipse.sdk</artifactId>
						<type>eclipse-feature</type>
					</dependency>
				</dependencies>
			</configuration>
			<executions>
				<execution>
					<goals>
						<goal>eclipse-run</goal>
					</goals>
					<phase>validate</phase>
				</execution>
			</executions>
		</plugin>
	</plugins>
</build>

where rootDir contains mirrors of p2 repositories.

When I try to run it in Maven offline mode with option -o then the TPD generator does find all locally stored artifacts from Maven central but it does not find the locally stored artifacts from other remote (company internal) repositories.

How should I configure the call of the TPD generator to use the local maven repository only?

The file mytarget.targetplatform uses the

maven ... {

}

syntax to integrate Maven artifacts into the target platform of the target feature.
