how to relocate package inside jar for gradle dependencies

currently I am using a package call a.jar. Unfortunately that this jar includes a com.example.b package with some customized changes to code base inside com.example.b.

Now I want to have some latest cool features from com.example.b package in b.jar from github.

I think the best solution (not sure how it can be done) is to relocate latest com.example.b to com.example.standalone.b , so that the a.jar can still use its customized com.exampl.b source, while inside project I can use com.example.standalone.b package.

I did research for shadow plugin, but seems it rename package by package name globally, so that the package (com.example.b) in both jars (a.jar and b.jar) would be also renamed and have conflict.

May I know how to do this for specific jar, like below example?

implementation a.jar:1.0
implementation (b.jar:2.0) {
   rename 'com.example.b' to 'com.example.standalone.b'
}
gradle android java

finally i managed to solve it by below configuration in goovy gradle.


configurations {
    relocateB // just define a separate configuration
}


task relocateB (type: ShadowJar) {
    def pkg = 'com.example.b' // lib to relocate
    relocate pkg, "com.example.standalone.b" // we want to relocate the above package
    configurations = [project.configurations.relocateB] // our configuration from above
    dependencies {
        // you must exclude below files in 'kotlin_module' and 'kotlin_builtins' extension, 
        // otherwise you won't be able to import `com.example.standalone.b` in kotlin files. 
        // This is a bug from Kotlin, consumed two days for me to solve. 
        // (https://youtrack.jetbrains.com/issue/KT-25709)
        exclude '**/*.kotlin_metadata'
        exclude '**/*.kotlin_module'
        exclude '**/*.kotlin_builtins'
    }
}


tasks.withType(JavaCompile) {
    compileTask -> compileTask.dependsOn relocateB
}



dependencies {
    ...
    relocateB ('com.example.b:2.2.3')
    api tasks.relocateB.outputs.files
    api 'com.example.a' // original package that won't be polluted
    ...
}
