IDE fails to resolve correct class when duplicate classes exist across multiple JARs (shaded vs non-shaded)

Description

The class org.apache.hadoop.security.authentication.server.AuthenticationHandler is present in both the jars i have:

• hadoop-client-api.jar (shaded version)
• hadoop-auth.jar (non-shaded version)

In the shaded JAR (hadoop-client-api.jar), AuthenticationHandler references HttpServletRequest from a relocated (shaded) servlet package.
In hadoop-auth.jar, the same class references javax.servlet.HttpServletRequest.

This leads to ambiguous class resolution in VS Code.
In our case, the VS Code Java extension mistakenly resolves the shaded AuthenticationHandler from hadoop-client-api.jar instead of the correct one from hadoop-auth.jar, resulting in a type mismatch when extending the class.

Environment

Hadoop version: 3.4.0
Java version: 17.0.16
Build tool: Gradle 8.14
IDE: VS Code with Java extension (vscjava.vscode-gradle 3.17.1)

Steps to Reproduce

• Create a Gradle project depending on two JARs that contain the same class name.
• One JAR uses a shaded package (e.g., org.apache.hadoop.shaded.*).
• Reference the class from the unshaded JAR.
• Observe that VS Code reports type mismatch or class conflict, while Gradle CLI builds successfully.

从 issue 中描述的 Gradle 复现开始，使用来自 shaded 和 unshaded JAR 的重复类。跟踪 VS Code Java extension 相比 Gradle CLI 如何解析该类，并验证在选择 unshaded AuthenticationHandler 且不存在类型不匹配时补全是否正常。
