[Fix]--java_out:user.proto:user.proto:cannot generate Java output because the file ' s

Generate code files with a. proto file when using protocol buffer times wrong

Using commands

Protoc.exe--java_out C:\logs\ User.proto

User.proto file content format is as follows

Message user{    require D string userName = 1[default= ""];                 & nbsp;                                                                   Required String password = 2[ default= ""];                                                                                  }                            The following error occurred while using the cmd command

--java_out:user.proto:user.proto:cannot generate Java output because the file
' s outer class name, ' User ', matches the name of the one of the types declared Insid
E it. Either rename the type or use the Java_outer_classname option to s
Pecify a different outer class name for the. Proto file.

Workaround:

Cause User.proto file name and the class name inside duplicate, the file name is user inside the content message user uses user

Modify the User.proto file name to not and the inside of the class name is repeated, it is changed to Userprotobuff

Then run Protoc.exe--java_out c:\logs\ Userprotobuff.proto run successfully.

Second workaround:

Add an I line to the Ptoto file

Option java_outer_classname="Reservationtypeouterclass";
To specify the class name of the generated Java class
