build.gradle

signingConfigs {
    robert {
        storePassword 'robert'
        storeFile file('/Users/bournewang/Documents/Project/android.keystore')
        keyPassword 'robert'
        keyAlias 'mike'
    }
}

解决方案：

Check your keystore file for first, in you example you creating file with name my-release-key.keystore. If its correct and really present in folder Users/bournewang/Documents/Project check alias, in your example it is -alias alias_name, but in config you specified alias mike

大意是：

2.keyAlias不对

另：想知道真正原因的话，可以查看

To find out what's wrong you can use gradle's singingReport command.

On mac:

./gradlew signingReport
On Windows:

gradle signingReport
