[移动开发]Android 自动设置版本号与版本名称

// version -------------------------------------------------
updateVersion()

def updateVersion() {
    def propertiesFile = file("build.properties")
    Properties properties = readProperties(propertiesFile)

    def versionMajor = properties["version_major"].toString().toInteger()
    def versionMinor = properties["version_minor"].toString().toInteger()
    def versionPatch = properties["version_patch"].toString().toInteger()
    def versionBuild = properties["version_build"].toString().toInteger()

    if (isReleaseTask()) {
        System.out.println(">>> Building Release...")
        versionPatch++
        versionStore++
        versionBuild = 0

        writeProperties(propertiesFile, properties)
    }
    if (isTestTask()) {
        System.out.println(">>> Running Tests...")
        versionBuild++

    android.defaultConfig.versionCode = versionStore
    android.defaultConfig.versionName = versionName
}

def isTestTask() {
    def tasks = gradle.getStartParameter().getTaskNames()
    return ":app:testDebugUnitTest" in tasks || "testDebugUnitTest" in tasks ||
            ":app:testReleaseUnitTest" in tasks || "testReleaseUnitTest" in tasks
}

    return ":app:assembleRelease" in tasks || "assembleRelease" in tasks ||
            ":app:bundleRelease" in tasks || "bundleRelease" in tasks

static Properties readProperties(propertiesFile) {
    if (propertiesFile.canRead()) {
        Properties properties = new Properties()
        def inputStream = new FileInputStream(propertiesFile)
        properties.load(inputStream)
        inputStream.close()
        return properties
    } else {
        def message = ">>> Could not read " + propertiesFile.name + " file!"
        System.err.println(message)
        throw new GradleException(message)
    }
}

def static writeProperties(propertiesFile, properties) {
    def writer = propertiesFile.newWriter()
    properties.store(writer, "Build Properties")
    writer.close()
}

根目录新建文件? build.properties内容如下

#Build Properties
#Sat Aug 07 14:32:46 EDT 2021

version_store=1


version_major=1
version_patch=0
version_minor=0
version_build=0

在每次编译正式版本后版本就会加1?非常的人性化
