Identify ResolvedRepository Details

Help/Discuss
1

Hi,

I have a gradle file with list of dependencies. I also got 3-5 repositories.
I want to map/print dependency with repository details. Any suggestions ?

for example:

repositories {
  jcenter()
 mavenlocal()
}

Output:

org.apache:ant:10.0 ==> jcenter()

The information about which repository a dependency came from is not available, at least not in a way Iā€™ve been able to find. I asked a similar question a while back, but in my case I was looking for the URL. Iā€™m afraid youā€™re probably out of luck, without looking at modifying Gradleā€™s source

However, depending how bad you want/need this, you could create subprojects, each with one of the repositories, then add the dependencies to a configuration in those projects and enumerate Configuration#getIncoming()#getResolutionResult()#getAllDependencies() looking for instances of ResolvedDependencyResult.

repositories {
    jcenter()
}
configurations {
    xyz
}
dependencies {
    xyz ...
}
task showDeps {
    doLast {
        println "Resolvable deps in jcenter():"
        println configurations.xyz.incoming.resolutionResult.allDependencies.findAll { dep ->
            dep instanceof ResolvedDependencyResult
        }.join( '\n    ')
    }
}

Thanks Chris,
I will try your inputsā€¦
I think there are more points to consider here. The gradle cache , local repository access, etc.

Another way, I am thinking is to develop a plugin which does the following :
#1. Get list of Maven / External repositories as specified in build file (order) - I am trying to find the API. Help me if you can.
#2. Search each Repo for the artifact and display the first Match.

I am also trying to understand how gradle prints the dependency resolution in its debug log. Any pointers ?

Thanks

I believe the RepositoryHandler object that backs repositories is ordered.

println repositories.collect {"${it.name} - ${it.url}"}.join('\n')

See if that follows the ordering when you move things around.

Chris Your idea seems promising. But I am trying to understand how I can create sub-project on the fly and remove them.

You can create virtual/dynamic subprojects using settings.gradle (which you could write a settings plugin for if youā€™d like), but thereā€™s no way to remove them during the execution of the build (and you probably donā€™t need to in my opinion).
Iā€™ve written such a settings plugin for a deployment tool that needed to resolve dependencies from promotion-level specific repositories. Iā€™ll reply with some examples once I have some time to ā€œpublic-ifyā€ it.

I tried with ProjectBuilder.builder().build() to get a project for now.
I added the repo to dummy project using
project.getRepositories().add(0, repoFromParent);
Hitting below error message. Is there any step I need to follow to convert MavenRepository to ResolutionAwareRepository?

Caused by: java.lang.ClassCastException: Failed to cast object org.gradle.api.internal.artifacts.repositories.DefaultMavenArtifactRepository_Decorated@7885611b of type org.gradle.api.internal.artifacts.repositories.DefaultMavenArtifactRepository_Decorated to target type org.gradle.api.internal.artifacts.repositories.ResolutionAwareRepository.

I am able to complete this. I will try to publish this as a separate plugin if possible.
