1. signingConfigs {  
2.     robert {  
3.         storePassword 'robert'  
4.         storeFile file('/Users/bournewang/Documents/Project/android.keystore')  
5.         keyPassword 'robert'  
6.         keyAlias 'mike'  
7.     }  
8. } 

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
