========================================================== ====================

The incorrect cycle should be a coding problem.

125 lines use Chinese comments

Because Gradle uses GBK by default, but the comments in java files use UTF-8 for Chinese
So there is a problem

Set the Gradle compilation encoding:

Method

Open the project structure
Structure

Open the gradle File

Join

// Set the Encoding
Tasks. withType (Compile ){
Options. encoding = "UTF-8"
}
 
Run the command line again to check whether there are any errors.
If not, check your java file encoding.
Into UTF-8

Compile it again!
