gradle：統一版本

統一第三方庫的版本：

參考：Android組件化開發實踐（十）：通過Gradle插件統一規範

• 示例一：

configurations.all {
    resolutionStrategy {
        force 'com.github.bumptech.glide:glide:4.2.0'
        force 'com.github.bumptech.glide:compiler:4.2.0'
    }
}

• 示例二：

def SUPPORT_VERSION = "26.1.0"
def MULTIDEX_VERSION = "1.0.2"
def GSON_VERSION = "2.8.0"
def KOTLIN_VERSION = "1.3.40"

ConfigurationContainer container = project.configurations
container.all { Configuration conf ->
    ResolutionStrategy rs = conf.resolutionStrategy
    rs.force 'com.google.code.findbugs:jsr305:2.0.1'
    //統一第三方庫的版本號
    rs.eachDependency { details ->
        def requested = details.requested
        if (requested.group == "com.android.support") {
            //強制所有的 com.android.support 庫採用固定版本
            if (requested.name.startsWith("multidex")) {
                details.useVersion(MULTIDEX_VERSION)
            } else {
                details.useVersion(SUPPORT_VERSION)
            }
        } else if (requested.group == "com.google.code.gson") {
            //統一 Gson 庫的版本號
            details.useVersion(GSON_VERSION)
        } else if (requested.group == "org.jetbrains.kotlin") {
            //統一內部 kotlin 庫的版本
            details.useVersion(KOTLIN_VERSION)
        }
    }
}

統一sdk版本

def MIN_SDK = 19
def TARGET_SDK = 26
def COMPILE_SDK = "android-26"

project.afterEvaluate {
    def android = project.extensions.getByName("android")

    //強制統一 compileSdkVersion、 minSdkVersion、targetSdkVersion
    String compileSdkVersion = android.compileSdkVersion
    int targetSdkVersion = android.defaultConfig.targetSdkVersion.apiLevel
    int minSdkVersion = android.defaultConfig.minSdkVersion.apiLevel
    if (compileSdkVersion != COMPILE_SDK) {
        throw new GradleException("compileSdkVersion , must be  ${COMPILE_SDK}")
    }
    if (minSdkVersion != MIN_SDK) {
        throw new GradleException("minSdkVersion , must be ${MIN_SDK}")
    }
    if (targetSdkVersion != TARGET_SDK) {
        throw new GradleException("targetSdkVersion , must be  ${TARGET_SDK}")
    }
}
