Download previously published jar from private maven repository

Help/Discuss

Hi all
I have to download a previously published jar file from a private maven repository and upload/publish it to another private maven repository. I tried the following:

repositories {
    maven {
        url = 'https://maven.pkg.github.com/my-org/my-repo'
        credentials {
            username = 'my-user'
            password = 'my-password'
        }
    }
}

configurations {
    download { transitive = false }
}

dependencies {
    download "${project.group}:${project.name}:${project.version}"
}

task downloadPackage(type:Copy) {
    from configurations.download
    into "${buildDir}/libs"
}

task upload(dependsOn: downloadPackage) {
    doFirst {
        myUploadMethod configurations.download.singleFile
    }
}

However, the download does not work since the dependency resolution tries to find the jar file locally over the implicit project dependency, i.e.

./gradlew my-sub-project:dependencies --configuration download

> Task :my-sub-project:dependencies

------------------------------------------------------------
        Project :my-sub-project
------------------------------------------------------------

        download
\--- my-group:my-sub-project:1.0.0 -> project :my-sub-project (*)

(*) - dependencies omitted (listed previously)

I tried to substitute the project dependency with the following modification to avoid the dependency omitting, but without success

configurations {
    download {
        transitive = false
        resolutionStrategy {
            dependencySubstitution {
                substitute project(':my-sub-project') with module("${project.group}:${project.name}:${project.version}")
            }
    }
}

Is there any way to download the jar file of the own sub-project from the remote maven repository?

Any input or feedback is highly appreciated. Many thanks and best regards
