Update classpath based on java.project.referencedLibraries when modifications in pointed folders

Environment

• Operating System:
• JDK version:
• Visual Studio Code version:
• Java extension version:

Steps To Reproduce

• have a folder defined in java.project.referencedLibraries outside of workspace. For instance:

	"java.project.referencedLibraries": [
		"/home/apupier/.config/Code/User/globalStorage/redhat.vscode-camelk/java-dependencies-3.7.0/dependencies/*.jar"
	]

• list of jars is modified inside /home/apupier/.config/Code/User/globalStorage/redhat.vscode-camelk/java-dependencies-3.7.0/dependencies/

[Please attach a sample project reproducing the error]
Please attach logs

Current Result

the classpath is not refreshed.

Expected Result

Either:

• automatically detect it and refresh
• provide a command to call a refresh

Additional Informations

any light workaround for it? (or already existing API?)

heavy workarounds:

• remove the entry, then readd in the settings
• call "Clean java language Server workspace"

首先跟踪 java.project.referencedLibraries 设置的处理方式，以及扩展如何响应工作区外被引用文件夹的变化。将现有的“Clean java language Server workspace”解决方法与所请求的自动刷新或命令进行比较，然后验证添加或删除匹配的 JAR 是否会刷新 classpath。
