Multi-module Maven project does not work

I created a multi-module Maven project and tried to open the root folder in Visual Studio Code. When I try to work with any of the sub-modules, I do not get any linting, formatting, refactoring, etc... I tried Add Folder to Java Source Path but that does not work either. I have no issues working with this project in other IDE's, including Eclipse.

Environment

• Operating System: Windows 10
• JDK version: 1.8.0.201
• Visual Studio Code version: 1.14.1
• Java extension version: 0.55.1

Steps To Reproduce

1. Clone example project:

git clone https://github.com/hashdelta/stix-pattern-evaluator-examples.git
cd stix-pattern-evaluator-examples
git checkout develop

2. Open project in VSCode

Current Result

The plugin does not recognize the children modules, thus does not provide any kind of Java semantics support - no linting, formatting, refactoring, etc...

Expected Result

You should be able to get semantics support for any Java class when you open the parent. It should be one cohesive project.

Additional Informations

The only way to work with the sub modules is by opening the module in its own VSCode instance. This does not work for me, as one of my projects consists of over 20+ modules.

I have verified in Eclipse, NetBeans, and IntelliJ that the GitHub project has no issues.

Clonate il repository stix-pattern-evaluator-examples, passate a develop e aprite la relativa cartella radice in VS Code. Confrontate il progetto aperto dalla radice con l’apertura separata di un modulo, verificando linting, formattazione e refactoring tra i moduli figli. Il lavoro è completo quando la semantica Java funziona in modo coerente per le classi di ogni sottomodulo; non sono indicati né un file sorgente né un test, quindi è necessario individuare prima il percorso pertinente per l’importazione del progetto.
