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
