In fact, this problem has been plagued for a long time, but no impact on the compilation, has been put, and today, I have met, it is not over, to find a solution, and then, the answer is all the same, and also tried, no use, too much.
The problem is that the code has Chinese, Chinese is in the comments, the time is completely normal to display, but the compile time Gradle will error, but it can be compiled successfully. This Nima, the real egg hurts. Hint information is also garbled, do not ask me since garbled the following information you are how to come out, this is not important, the important is how to solve.
Compile-time gradle error message "Encoding UTF-8 non-mapped characters"
Set up the character set in the settings first,
Settings->file Encodings->ide Encodeing->utf-8
Settings->file Encodings->project Encodeing->utf-8
If that doesn't work, keep looking down, if you can, the following steps are ignored.
Many of the online solutions are in the corresponding module under the Build.gradle to add the following configuration
tasks.withType(Compile) { options.encoding"UTF-8" }
However, this configuration can be effective before gradle2.0, and will not take effect after gradle2.0, because
Compile has been renamed to Javacompile
So the configuration you need to add after gradle2.0 is as follows
tasks.withType(JavaCompile) { options.encoding"UTF-8" }
