How to remove duplicate libraries in ear archive?

Question

Java

Have an earphone

project.ear
    |-META-INF
    |-dependency.jar
    |-dependency1.jar
    |-dependency2.jar

I wanted to remove the dependencies in the lib folder and added it to the rom <defaultLibBundleDir>/lib</defaultLibBundleDir>
, it became like this:

project.ear
    |-META-INF
    |-lib
        |-dependency.jar
        |-dependency1.jar
        |-dependency2.jar
    |-dependency.jar
    |-dependency1.jar
    |-dependency2.jar

why did the libraries remain in the root?
