Answer 1

I

Add resolveDependencies task in build.gradle:

task resolveDependencies {
    doLast {
        project.rootProject.allprojects.each { subProject ->
            subProject.buildscript.configurations.each { configuration ->
                configuration.resolve()
            }
            subProject.configurations.each { configuration ->
                configuration.resolve()
            }
        }
    }
}

and update Dockerfile:

ADD build.gradle /opt/app/
WORKDIR /opt/app
RUN gradle resolveDependencies

ADD . .

RUN gradle build -x test --parallel && \
    touch build/libs/api.jar

Bellow is what I do now:

build.gradle

ext {
    speed = project.hasProperty('speed') ? project.getProperty('speed') : false
    offlineCompile = new File("$buildDir/output/lib")
}

dependencies {
    if (speed) {
        compile fileTree(dir: offlineCompile, include: '*.jar')
    } else {
        // ...dependencies
    }
}

task downloadRepos(type: Copy) {
    from configurations.all
    into offlineCompile
}

Dockerfile

ADD build.gradle /opt/app/
WORKDIR /opt/app

RUN gradle downloadRepos

ADD . /opt/app
RUN gradle build -Pspeed=true
