另一种方法是定义一个只在发行版上运行的任务。

android {
  ...
  signingConfigs {
     release {
        // We can leave these in environment variables
        storeFile file('nameOfKeystore.keystore')
        keyAlias 'nameOfKeyAlias'

        // These two lines make gradle believe that the signingConfigs
        // section is complete. Without them, tasks like installRelease
        // will not be available!
        storePassword "notYourRealPassword"
        keyPassword "notYourRealPassword"

     }
  }
  buildTypes {
     ...
     release {
        signingConfig signingConfigs.release
        ...
     }
  }
  ...
}

task setupKeystore << {
final Console console = System.console();
if (console != null) {
    //def keyFile = console.readLine(“\nProject: “ + project.name + “Enter keystore path: "))
    //def keyAlias = console.readLine(“Project: “ + project.name + “Enter key alias: ")
        def storePw = new String(console.readPassword(“Project: “ + project.name + “. Enter keystore password: "))
        def keyPw  = new String(console.readPassword(“Project: “ + project.name + “.Enter keystore password: "))

    //android.signingConfigs.release.storeFile = file(keyFile);
    //android.signingConfigs.release.keyAlias = keyAlias
        android.signingConfigs.release.storePassword = storePw
        android.signingConfigs.release.keyPassword = keyPw
}
}

//Validate t
def isReleaseConfig = gradle.startParameter.taskNames.any {it.contains('Release') }
if (isReleaseConfig) {
    setupKeystore.execute();
}

如果您像我一样，只是希望能够在您的设备上运行该版本以进行测试，那么可以考虑为签名创建第二个密钥存储库，这样您就可以简单地将其密码放入您的构建中。Gradle无需担心您的市场密钥存储安全。

您可以通过单击Build/Generate Signed APK/ create new…来创建一个新的密钥库。

如果你像我一样通过命令行构建apk，那么你可以提供签名配置作为参数。

将此添加到build.gradle中

def getStore = { ->
    def result = project.hasProperty('storeFile') ? storeFile : "null"
    return result
}

def getStorePassword = { ->
    def result = project.hasProperty('storePassword') ? storePassword : ""
    return result
}

def getKeyAlias = { ->
    def result = project.hasProperty('keyAlias') ? keyAlias : ""
    return result
}

def getKeyPassword = { ->
    def result = project.hasProperty('keyPassword') ? keyPassword : ""
    return result
}

让你的signingconfig像这样

signingConfigs {
    release {
        storeFile file(getStore())
        storePassword getStorePassword()
        keyAlias getKeyAlias()
        keyPassword getKeyPassword()
    }
}

然后像这样执行gradlew

./gradlew assembleRelease -PstoreFile="keystore.jks" -PstorePassword="password" -PkeyAlias="alias" -PkeyPassword="password"

注意@sdqali的脚本会(至少在使用Gradle 1.6时)要求输入密码 任何时候调用gradle任务。因为你只在做gradle assemblerrelease(或类似)时需要它，你可以使用下面的技巧:

android {
    ...
    signingConfigs {
        release {
            // We can leave these in environment variables
            storeFile file(System.getenv("KEYSTORE"))
            keyAlias System.getenv("KEY_ALIAS")

            // These two lines make gradle believe that the signingConfigs
            // section is complete. Without them, tasks like installRelease
            // will not be available!
            storePassword "notYourRealPassword"
            keyPassword "notYourRealPassword"
        }
    }
    ...
}

task askForPasswords << {
    // Must create String because System.readPassword() returns char[]
    // (and assigning that below fails silently)
    def storePw = new String(System.console().readPassword("Keystore password: "))
    def keyPw  = new String(System.console().readPassword("Key password: "))

    android.signingConfigs.release.storePassword = storePw
    android.signingConfigs.release.keyPassword = keyPw
}

tasks.whenTaskAdded { theTask -> 
    if (theTask.name.equals("packageRelease")) {
        theTask.dependsOn "askForPasswords"
    }
}

注意，我还必须添加以下(在android下)使其工作:

buildTypes {
    release {
        signingConfig signingConfigs.release
    }
}

对于Kotlin脚本(build.gradle.kts)

您不应该将签名凭据直接放在build.gradle.kts文件中。相反，凭证应该来自不受版本控制的文件。

放置一个文件签名。找到特定于模块的build.gradle.kts的属性。别忘了把它添加到你的。gitignore文件!

signing.properties

storeFilePath=/home/willi/example.keystore
storePassword=secret
keyPassword=secret
keyAlias=myReleaseSigningKey

build.gradle.kts

android {
    // ...
    signingConfigs {
        create("release") {
            val properties = Properties().apply {
                load(File("signing.properties").reader())
            }
            storeFile = File(properties.getProperty("storeFilePath"))
            storePassword = properties.getProperty("storePassword")
            keyPassword = properties.getProperty("keyPassword")
            keyAlias = "release"
        }
    }

    buildTypes {
        getByName("release") {
            signingConfig = signingConfigs.getByName("release")
            // ...
        }
    }
}

你也可以使用gradle的-P命令行选项来帮助签名。在你的构建中。gradle，像这样添加singingConfigs:

signingConfigs {
   release {
       storeFile file("path/to/your/keystore")
       storePassword RELEASE_STORE_PASSWORD
       keyAlias "your.key.alias"
       keyPassword RELEASE_KEY_PASSWORD
   }
}

然后像这样调用gradle build:

gradle -PRELEASE_KEYSTORE_PASSWORD=******* -PRELEASE_KEY_PASSWORD=****** build

如果您愿意，可以使用-P来设置storeFile和keyAlias。

这基本上是Destil的解决方案，但带有命令行选项。
