推荐答案

调用 java 可执行文件，带有 -verbose：class 参数。这将产生如下输出：

Invoke the java executable with the -verbose:class argument. This will produce output like:

[从文件中加载org.apache.log4j.helpers.ThreadLocalMap：/ C：/.../ 1.2.14 / log4j-1.2.14.jar]

[从文件中加载org.apache.commons.cli.Option：/ C：/.../ commons-cli-1.2.jar]

[Loaded org.apache.log4j.helpers.ThreadLocalMap from file:/C:/.../1.2.14/log4j-1.2.14.jar]
[Loaded org.apache.commons.cli.Option from file:/C:/.../commons-cli-1.2.jar]
