Autoincrement VersionCode with gradle extra properties

Question

I\'m building an Android app with gradle. Until now I used the Manifest file to increase the versionCode, but I would like to read the versionCode from an external file and

Answer 1

in the Gradle 5.1.1 version on mac ive changed how the task names got retrieved, i althought tried to get build flavour / type from build but was to lazy to split the task name:

def versionPropsFile = file('version.properties')
if (versionPropsFile.canRead()) {
    def Properties versionProps = new Properties()

    versionProps.load(new FileInputStream(versionPropsFile))

    def value = 0

    def runTasks = gradle.getStartParameter().getTaskRequests().toString()

    if (runTasks.contains('assemble') || runTasks.contains('assembleRelease') || runTasks.contains('aR')) {
        value = 1
    }

    def versionMajor = 1
    def versionMinor = 0
    def versionPatch = versionProps['VERSION_PATCH'].toInteger() + value
    def versionBuild = versionProps['VERSION_BUILD'].toInteger() + 1
    def versionNumber = versionProps['VERSION_NUMBER'].toInteger() + value

    versionProps['VERSION_PATCH'] = versionPatch.toString()
    versionProps['VERSION_BUILD'] = versionBuild.toString()
    versionProps['VERSION_NUMBER'] = versionNumber.toString()

    versionProps.store(versionPropsFile.newWriter(), null)

    defaultConfig {
        applicationId "de.evomotion.ms10"
        minSdkVersion 21
        targetSdkVersion 28
        versionCode versionNumber
        versionName "${versionMajor}.${versionMinor}.${versionPatch} (${versionBuild})"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        signingConfig signingConfigs.debug
    }

} else {
    throw new GradleException("Could not read version.properties!")
}
