Gradle offline how to cache the dependencies

Question

I am doing nightly gradle builds on a server where I checkout the repositories from git and build them.However, there is a proxy where gradle cannot download any repository. I tried running gradlew offline mode then I get an error telling me that

"No cached version of" and then the name of the dependency.

This is obviously because I never downloaded the dependency, I was thinking of manually downloading the dependencies cache them and use that gradle cache on the server where builds can access it. My question is as follows :

1. Is there any way I can download a .jar file or .pom file manually and then cache them ?_
2. How would i cache a jar file in the $Home/.gradle/caches directory ? I tried just putting it there but it doesn't work .

any ideas?

Answer 1

Usually Gradle retrieves dependencies on demand, only if and when they are need. To make Gradle download all dependencies beforehand (and thus populate the local cache), you can use a task like

task resolveAllDependencies {
    description "Resolves all transitive dependencies (e.g. to build offline later)."

    doLast {
        configurations.all {
            it.resolve()
        }
    }
}

After running this task, you should be able to successfully build with --offline.

In Android Studio sync the dependencies once then go to

• File > Settings > Build & Execution > Gradle > Enable Offline Mode > Ok!
