Many answers on the Internet are to add the following configuration to the build.gradle under the corresponding module

tasks.withType(Compile) {  
    options.encoding = "UTF-8"  
}  

However, this configuration can take effect before gradle2.0, but cannot take effect after gradle2.0, the reason is that

Compile has been renamed to JavaCompile

So the configuration that needs to be added after gradle2.0 is as follows

tasks.withType(JavaCompile) {  
    options.encoding = "UTF-8"  
}
