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")
            // ...
        }
    }
}

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。

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
    }
}

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=*****

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

keyPassword=secret
keyAlias=myReleaseSigningKey

            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
            // ...
        }
    }
}

android {
    compileSdkVersion 17
    buildToolsVersion "19.0.3"

    defaultConfig {
        minSdkVersion 9

    }

    File signFile = rootProject.file('sign/keystore.properties')
    if (signFile.exists()) {
        Properties properties = new Properties()
        properties.load(new FileInputStream(signFile))
        signingConfigs {

                keyAlias properties['keyAlias']
                keyPassword properties['keyPassword']
            }
        }
    }
