比之前的答案更简单的方法:

把它放到~/.gradle/gradle.properties中

RELEASE_STORE_FILE={path to your keystore}
RELEASE_STORE_PASSWORD=*****
RELEASE_KEY_ALIAS=*****
RELEASE_KEY_PASSWORD=*****

修改你的应用/构建。Gradle，并将其添加到android{代码块:

...    
signingConfigs {

   release {
       storeFile file(RELEASE_STORE_FILE)
       storePassword RELEASE_STORE_PASSWORD
       keyAlias RELEASE_KEY_ALIAS
       keyPassword RELEASE_KEY_PASSWORD

       // Optional, specify signing versions used
       v1SigningEnabled true
       v2SigningEnabled true
   }
}

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

然后你可以运行gradle assemblerrelease

另请参阅signingConfigs Gradle DSL的参考

对于Groovy (build.gradle)

您不应该将签名凭据直接放入构建中。gradle文件。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。特定于模块构建的属性。Gradle被找到了。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

android {
    // ...
    signingConfigs{
        release {
            def props = new Properties()

            def fileInputStream = new FileInputStream(file('../signing.properties'))
            props.load(fileInputStream)
            fileInputStream.close()

            storeFile = file(props['storeFilePath'])
            storePassword = props['storePassword']
            keyAlias = props['keyAlias']
            keyPassword = props['keyPassword']
        }
    }

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

现在是2019年，我需要用V1 (jar签名)或V2(完整APK签名)签署APK。我谷歌了“生成签名apk gradle”，它把我带到了这里。我把原来的解加到这里。

signingConfigs {
    release {
        ...
        v1SigningEnabled true
        v2SigningEnabled true
    }
}

我最初的问题:如何从构建开始使用V1 (Jar签名)或V2(完整的APK签名)。gradle文件

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
    }
}

您可以从命令行请求密码:

...

signingConfigs {
  if (gradle.startParameter.taskNames.any {it.contains('Release') }) {
    release {
      storeFile file("your.keystore")
      storePassword new String(System.console().readPassword("\n\$ Enter keystore password: "))
      keyAlias "key-alias"
      keyPassword new String(System.console().readPassword("\n\$ Enter keys password: "))
    } 
  } else {
    //Here be dragons: unreachable else-branch forces Gradle to create
    //install...Release tasks.
    release {
      keyAlias 'dummy'
      keyPassword 'dummy'
      storeFile file('dummy')
      storePassword 'dummy'
    } 
  }
}

...

buildTypes {
  release {

    ...

    signingConfig signingConfigs.release
  }

  ...
}

...

if-then-else块防止在构建版本时请求密码。虽然else分支是不可达的，它欺骗Gradle创建一个安装…发布的任务。

基本信息。正如https://stackoverflow.com/a/19130098/3664487所指出的，“Gradle脚本可以使用System.console()提示用户输入。readLine方法。”不幸的是，Gradle总是会要求密码，即使你在构建一个调试版本(参见如何使用Gradle创建一个发布签名apk文件?)幸运的是，这是可以克服的，如上所述。

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"
