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.

克隆 stix-pattern-evaluator-examples 仓库，切换到 develop，并在 VS Code 中打开其根文件夹。将从根目录打开的项目与单独打开某个模块的情况进行比较，检查各子模块中的 linting、格式化和重构。完成的标准是：Java 语义能够对每个子模块中的类协同一致地工作；没有指定源文件或测试，因此必须先找到相关的项目导入路径。
