changing .classpath file reference

I am working with a huge legacy application which was built using Ant + Eclipse. There exists a .classpath file already with references like this (which im guessing eclipses creates):

<classpathentry kind="var" path="LIB_ROOT/json/json.jar"/>
<classpathentry kind="var" path="LIB_ROOT/apache/commons-logging.jar"/>
<classpathentry kind="src" path="src/"/>
<classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER"/>

Out of the box this doesnt work in vscode as it has no idea wht LIB_ROOT is.

My thought then is since this is a giant ant project and would be quite an effort to convert to maven (cant do gradle as it's also a java 1.8 project), i could do one of the following:

1. simply create an ant task to generate a new .classpath file, say .classpath_vscode
2. or simply generate a line separated list for each libary, and possibly referecne this file as the list values for settings.json -> java.project.referencedLibraries

For #1, is it possible to tell the java extension to use a different .classpath file? (this way devs can move to vscode, but still also work in eclipse using the original .classpath file.

For #2 - would i be able to reference a separate file as the source for the list?

Thanks

首先检查 Java 扩展对 .classpath 文件和 settings.json 的处理方式，尤其是 java.project.referencedLibraries。比较所请求的备用 .classpath 工作流和外部库列表工作流；当受支持的配置路径已记录，或其中一个所请求的工作流已实现并在 VS Code 中验证后，即可视为完成。
