"The signing configuration should be specified in Gradle build scripts"... I did it

Question

I have a big issue when I come to sign my application: I have set the signing configuration in accordance with the doc:

signingConfigs {
    release {
        storeFile file("lomapnew.keystore")
        storePassword "myPassword"
        keyAlias "myAlias"
        keyPassword "Something...."
    }
}

But I still get this error message: "The signing configuration should be specified in Gradle build scripts"

I'm going to go out on a limb and guess that you haven't set the signing configuration for the release build type. The debug build type is automatic, so it's not obvious that this is a necessary step for all other build types, including release.

You can apply the signing config like so:

android {
    signingConfigs {
        // It's not necessary to specify, but I like to keep the debug keystore
        // in SCM so all our debug builds (on all workstations) use the same
        // key for convenience
        debug {
            storeFile file("debug.keystore")
        }
        release {
            storeFile file("release.keystore")
            storePassword "myPassword"
            keyAlias "myAlias"
            keyPassword "Something...."
        }
    }

    buildTypes {
        /* This one happens automatically
        debug {
            signingConfig signingConfigs.debug
        }
        */
        release {
            signingConfig signingConfigs.release
        }
    }
}

Answer 2

I like to keep passwords out of my build file. Hence I create a properties file that I load with

def keystorePropertiesFile = rootProject.file("./local.properties")
def keystoreProperties = new Properties()
keystoreProperties.load(new FileInputStream(keystorePropertiesFile))

Then I define signingConfigs like so:

   signingConfigs {
    releaseSigning {
        storeFile file(keystoreProperties['storeFile'])
        storePassword keystoreProperties['keystore.live.storepassword']
        keyAlias = keystoreProperties['keystore.live.keyalias']
        keyPassword = keystoreProperties['keystore.live.keypassword']
    }
    debugSigning {
        storeFile file(keystoreProperties['storeFile'])
        storePassword keystoreProperties['keystore.debug.storepassword']
        keyAlias = keystoreProperties['keystore.debug.keyalias']
        keyPassword = keystoreProperties['keystore.debug.keypassword']
    }
}

This doesn't work well with the menu option "create Signed apk" so I create flavors:

    productFlavors {
    mydebug {
        signingConfig signingConfigs.debugSigning
    }
    myrelease {
        signingConfig signingConfigs.releaseSigning
    }
}

and now the signingconfigs work with the run button on the toolbar. For a default keystore the local.properties looks like

ndk.dir=/opt/sdk/ndk-bundle
sdk.dir=/opt/sdk
storeFile=/home/christine/.android/debug.keystore
keystore.debug.storepasswd=android
keystore.debug.keyalias=androiddebugkey
keystore.debug.keypassword=android
keystore.live.storepasswd=android
keystore.live.keyalias=androiddebugkey
keystore.livetest.keypassword=android

In your Jenkins build script, you need to create a symbolic link from local.properties to where the properties file is on your build server.
