DependencyResolver

Provides a simple API to check for, and download artifacts from Maven Central, Google Maven and Jitpack. It was created as a lightweight alternative to Eclipse aether for Android. But this would work on any OS.

It is recommended to use snapshot builds from jitpack.

For a proper example, checkout Main.kt.

For checking if an artifact exists (in the above mentioned repositories), you can simply do

import org.cosmic.ide.dependency.resolver.getArtifact

val groupId = "com.squareup.retrofit2"
val artifactId = "retrofit"
val version = "2.9.0"

val artifact = getArtifact(groupId, artifactId, version)
val repository = artifact.repository
if (repository != null) {
    println("Artifact exists in ${ repository.getName() }")
} else {
    println("Cannot find artifact.")
}

NOTE: If you only want to download the artifact, you can use the downloadTo method instead. For downloading an artifact with all of its dependencies, you can do

val output = File("<directory to download artifact>")
artifact.downloadArtifact(output)
