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=*****

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"

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

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
            // ...
        }
    }
}

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。

我在Ubuntu14.04工作。 vim ~ /。Bashrc和add 出口ANDROID_KEYSTORE = 出口ANDROID_KEYALIAS =

然后是构建。它集。

    final Console console = System.console();
if (console != null) {

    // Building from console
    signingConfigs {
        release {
            storeFile file(System.getenv("KEYSTORE"))
            storePassword new String(System.console().readPassword("\n\$ Enter keystore password: "))
            keyAlias System.getenv("KEY_ALIAS")
            keyPassword new String(System.console().readPassword("\n\$ Enter key password: "))
        }
    }

} else {

    // Building from IDE's "Run" button
    signingConfigs {
        release {

        }
    }

}
