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.

stix-pattern-evaluator-examples リポジトリをクローンし、develop をチェックアウトして、そのルートフォルダーを VS Code で開きます。ルートで開いたプロジェクトと、モジュールを個別に開いた場合を比較し、子モジュール全体で linting、フォーマット、リファクタリングを確認します。すべてのサブモジュールのクラスで Java semantics が一貫して機能すれば完了です。ソースファイルやテストは指定されていないため、まず関連する project-import path を見つける必要があります。
