就像@Destil说的，但允许其他没有钥匙的人建造: 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=*****

修改构建。这样Gradle:

...    
if(project.hasProperty("RELEASE_STORE_FILE")) {
    signingConfigs {    
       release {
           storeFile file(RELEASE_STORE_FILE)
           storePassword RELEASE_STORE_PASSWORD
           keyAlias RELEASE_KEY_ALIAS
           keyPassword RELEASE_KEY_PASSWORD
       }
    }
}

buildTypes {
    if(project.hasProperty("RELEASE_STORE_FILE")) {
        release {
            signingConfig signingConfigs.release
        }
    }
}
....

然后你可以运行gradle assemblerrelease 或 gradle构建

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
    }
}

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();
}

就我而言，我上传了错误的apk到另一个应用程序的发布中。

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

现在几乎所有的平台都提供了某种密匙环，所以没有理由留下明文密码。

我提出了一个简单的解决方案，使用Python密匙环模块(主要是配套的控制台脚本密匙环)和Groovy ['do'， 'something'].execute()特性的最小包装:

def execOutput= { args ->
    def proc = args.execute()
    proc.waitFor()
    def stdout = proc.in.text
    return stdout.trim()
}

使用这个函数，signingConfigs部分变成:

signingConfigs {
    release {
        storeFile file("android.keystore")
        storePassword execOutput(["keyring", "get", "google-play", storeFile.name])
        keyAlias "com.example.app"
        keyPassword execOutput(["keyring", "get", "google-play", keyAlias])
    }
}

在运行gradle assemblerrelease之前，你必须在你的keyring中设置密码，只有一次:

$ keyring set google-play android.keystore # will be prompted for the passwords
$ keyring set google-play com.example.app

释放快乐!
