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：

1.android.keystore可能不在指定目录下面

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
