Gradle uploadArchives via scp prompts for password muliple times

Question

I am trying out Gradle and am trying to upload jars to my Nexus repo using Wagon SCP as described in the Gradle user guide. I have taken the build file as specified in the user guide:

configurations {
    deployerJars
}

repositories {
    mavenCentral()
}

dependencies {
    deployerJars "org.apache.maven.wagon:wagon-ssh:1.0-beta-2"
}

uploadArchives {
    repositories.mavenDeployer {
        name = 'sshDeployer' // optional
        configuration = configurations.deployerJars
        repository(url: "scp://repos.mycompany.com/releases") {
            authentication(userName: "me", password: "myPassword")
        }
    }
}

(Of course with the exception that the URL and credentials are adapted to my repo.)

Now, when running gradle uploadArchives, the build freezes after a while. I cancelled the build and restarted it with info logging turned on and found that the script is prompting me for password:

gradle -i uploadArchives

Password:: 

Apparently, the password configured in the build script is ignored.

Anyway, I entered the password and then got prompted some more times, where I obeyed and re-entered the password.

Finally, the build completed sucessfully.

Afterwards I checked my repo and the artifact had been uploaded successfully.

So, uploading jars to a repo works.

However, that the gradle prompts me for password does not work for me, since I planned to use this in a automated build process with Jenkins.

NOW TO MY QUESTION: Does anyone know if there is a way to turn this password prompting off?

Answer 1

I don't know why it's prompting you for the password. That may be something to fix in a newer version of wagon. I do know that you can use this to avoid the need for a password:

repository(url: 'scp://example.com/var/repos') {
            authentication(userName: "me", privateKey: "/home/me/.ssh/id_rsa")
        }
