Package containing dot character not being parsed correctly

Issue Type: Bug

In the src folder of a Java Gradle project, there's the package structure:

projectRoot/
└── src/
    ├── main/
    │   ├── java/
    │   │   └── javasnap.domain/
    │   │       └── cli/
    │   │           └── ClStringArgs.java
    └── test/
        ├── java/
        │   └── javasnap.domain/
        │       └── cli/
        │           └── ClStringArgsTest.java

The ClStringArgs.java and ClStringArgsTest.java file contains the package declaration:

package javasnap.domain.cli;

Which is resulting in the package delcaration being highlighted as an error by VScode in both the test and production source file:

The declared package "javasnap.domain.cli" does not match the expected package "" Java(536871240)

It's also highlighting any reference to the class ClStringArgs in both the production and test source code with the following error:

ClStringArgs cannot be resolved to a type Java(16777218)

Splitting the directory name containing the dot character into two separate directories with one nested within the other causes this error to go away.

This package naming is valid for Gradle (and Java) to be able to compile and run source code. Attempting to add a directory to the Java Source Path via VScode results in the following message:

Unsupported operation. Please use build.gradle file to manage the source directories of gradle project.

This source directory structure is the default structuring of Gradle builds and this package naming convention is valid and used by multiple Java libraries. Can this bug get fixed or the feature of being able to resolve package names containing the dot character correctly be added to the roadmap?

Reproduce el error con la estructura de Gradle mostrada, incluido el directorio javasnap.domain con puntos, ClStringArgs.java, ClStringArgsTest.java y build.gradle. Empieza rastreando cómo la extensión descubre los directorios de código fuente Java de Gradle; se considera terminado cuando las declaraciones de paquetes y las referencias se resuelven sin errores, mientras el proyecto sigue compilándose y ejecutándose.
