hvisser / build.gradle

Created May 22, 2014 13:26

Snippet of a build.gradle that uses Gradle properties for key store passwords. I usually do not check in gradle.properties and on the CI machine the properties are provided using the -P switch.

	apply plugin: 'android'

	// use the standard Gradle version property, handy if you use plugins that also rely on this
	version = "1.0"

	ext {
	// These properties are set in gradle.properties (not checked in to vcs) or using -P on the command line.
	// If they are not set, provide a default otherwise the build won't run.
	// Obviously, with the default password a release build will fail
	keyStorePassword = ext.has("keyStorePassword") ? ext.keyStorePassword : "not-set"
