Title says it all. How do I force gradle to download dependency sources

If you’re using eclipse or intellij plugins there’s support for doing this. Eg

apply plugin: 'java'
apply plugin: 'idea'
apply plugin: 'eclipse'

eclipse {
    classpath {
       downloadSources=true
       downloadJavadoc = true
    }
}
idea {
    module {
        downloadJavadoc = true
        downloadSources = true
    }
}

Or you can use an ArtifactResolutionQuery to do it programmatically

task copyJavadocsAndSources {
    inputs.files configurations.runtime
    outputs.dir "${buildDir}/download"
    doLast {
        def componentIds = configurations.runtime.incoming.resolutionResult.allDependencies.collect { it.selected.id }
        ArtifactResolutionResult result = dependencies.createArtifactResolutionQuery()
            .forComponents(componentIds)
            .withArtifacts(JvmLibrary, SourcesArtifact, JavadocArtifact)
            .execute()
        def sourceArtifacts = []
        result.resolvedComponents.each { ComponentArtifactsResult component ->
            Set<ArtifactResult> sources = component.getArtifacts(SourcesArtifact)
            println "Found ${sources.size()} sources for ${component.id}"
            sources.each { ArtifactResult ar ->
                if (ar instanceof ResolvedArtifactResult) {
                    sourceArtifacts << ar.file
                }
            }
        }

        copy {            
            from sourceArtifacts
            into "${buildDir}/download"
        }
    }
}

I tried both. It doesn’t work :frowning: . IntelliJ still decompiles it when I try to look at code of library.

#4

I can only guess that you didn’t actually run the tasks after adding the snippets.

Eg gradlew eclipse or gradlew copyJavadocsAndSources

#5

Did it now. Still the same thing.

#6

I just realised you are using intellij. Try gradle cleanIdea idea

#7

Task “cleanIdea” not found.

#8

Did you

apply plugin: 'idea'
#9

Yes. It doesn’t work.

#10

Can you tell a bit more about the project. Is it a multi-module build? Where are you applying the idea plugin? Are you only doing it for the root project? or are you applying it for all the java projects?

#11

It’s not multi module project. I’m applying it right after plugins have been declared e.g

plugins {
id ‘something’
// you know
}

apply plugin: ‘idea’
