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
            // ...
        }
    }
}

为了补充其他答案，你也可以放置gradle。属性文件与build一起放在您自己的模块文件夹中。Gradle，以防您的密钥库特定于一个项目。

然后在构建中生成signingconfig。gradle文件。

我设法解决它添加这段代码，并与gradle构建:

android {
    ...
    signingConfigs {
        release {
            storeFile file("release.keystore")
            storePassword "******"
            keyAlias "******"
            keyPassword "******"
        }
    }
    buildTypes {
        release {
            signingConfig signingConfigs.release
        }
    }
}

这将生成一个已签名的发布apk文件。

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();
}

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!
