imports are not resolved in maven multi module project

Hi,

I use vcode for a multi module project cumulocity-dynamic-mqtt-mapper, (branch develop).

The project structure is as follows:
|----mqtt-mapping-service
|  |----pom.xml
|----mqtt-mapping-interface
|  |----pom.xml
|----mqtt-mapping-extension
|  |----pom.xml
|----pom.xml

When ...

1. I open the project in vcode (extension pack vscjava.vscode-java-pack) and
2. navigate to the module mqtt-mapping-extension and
3. open class mqtt-mapping extension/src/main/java/mqtt/mapping/processor/extension/external/ProcessorExtensionCustomEvent.java
4. I see the following errors:
   The import mqtt.mapping.model cannot be resolvedJava(268435846) mqtt.mapping
   in the source editor:

Environment

• Operating System: MacOS
• JDK version: OpenJDK 64-Bit Server VM Zulu11.60+19-CA (build 11.0.17+8-LTS, mixed mode)- Visual Studio Code version:
• Java extension version: v0.25.12

Steps To Reproduce

1. clone the project (https://github.com/SoftwareAG/cumulocity-dynamic-mqtt-mapper/tree/develop)
2. navigate to the module mqtt-mapping-extensionand open class mqtt-mapping-extension/src/main/java/mqtt/mapping/processor/extension/external/ProcessorExtensionCustomEvent.java

Expected Result

When I open the same project in IntelliJ I don't get any errors. In can use classes from the module mqtt-mapping-interface in the module mqtt-mapping-extension.

Clone the linked cumulocity-dynamic-mqtt-mapper project on its develop branch and open mqtt-mapping-extension/src/main/java/mqtt/mapping/processor/extension/external/ProcessorExtensionCustomEvent.java in VS Code. Inspect how the Maven multi-module project is imported, using the root and module pom.xml files as the starting point. Done means imports from mqtt-mapping-interface resolve without Java diagnostics in the extension module.
