然后在构建中生成signingconfig。gradle文件。

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

如果您想避免在构建中硬编码您的密钥库和密码。gradle，你可以使用属性文件解释这里:处理签名配置与gradle

基本上:

1)创建一个myproject。属性文件在/home/[username]/。签名内容如下:

keystore=[path to]\release.keystore
keystore.password=*********
keyAlias=***********
keyPassword=********

2)创建gradle。属性文件(可能在你的项目目录的根目录)的内容:

MyProject.properties=/home/[username]/.signing/myproject.properties

3)在你的构建中参考它。这样Gradle:

    if(project.hasProperty("MyProject.properties")
        && new File(project.property("MyProject.properties")).exists()) {

    Properties props = new Properties()
    props.load(new FileInputStream(file(project.property("MyProject.properties"))))

    signingConfigs {
        release {
            storeFile file(props['keystore'])
            storePassword props['keystore.password']
            keyAlias props['keyAlias']
            keyPassword props['keyPassword']
        }
    }
}

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();
}

如果您不想看到不能在空对象上调用方法readLine()。你需要用gradle来写。第一个属性。

KEYSTORE_PASS=*****
ALIAS_NAME=*****
ALIAS_PASS=*****

我有几个问题，我把下面的行放在错误的地方:

signingConfigs {
    release {
        // We can leave these in environment variables
        storeFile file("d:\\Fejlesztés\\******.keystore")
        keyAlias "mykey"

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

确保你把signingConfigs部分放在了android部分:

android
{
    ....
    signingConfigs {
        release {
          ...
        }
    }
}

而不是

android
{
    ....
}

signingConfigs {
   release {
        ...
   }
}

很容易犯这个错误。
