Is there a question hidden somewhere? Especially a Gradle related one? Your JavaDoc annotations have many warnings and also 7 errors as your output tells you. So the JavaDoc tool fails to finish. Fix them and go on. ---

I can’t know what the error is, those error log are all error code, I’ve used UTF-8 encoding but nothing work.Meanwhile javadoc successfully generated, but task execution fails, I use `isFailOnError = false` then javadoc product exists ---

the javadoc tasks have garbled code, which is a hidden problem. ---

I’m sorry, but I don’t really understand what your are saying. The warnings and errors are all listed in the console output. I just cannot tell you which are the 7 errors because the output is in Chinese, which I don’t understand and the build scan obviously didn’t record properly. But I’d expect it to be properly readable in your console. ---

Sorry, my English is not good. There are errors in the decoding of these logs, do you know how to fix it? ![image](https://global.discourse-cdn.com/gradle/original/2X/0/00698be6155bafe3de6539f6cfc30d6bed935d0d.png) ---

What you underlined last should be the warnings, above - the 7 - should be the errors. I don’t know about the build scan, I reported that at [Chinese output in build scan garbled · Issue #25211 · gradle/gradle · GitHub](https://github.com/gradle/gradle/issues/25211), but I’d expect that if you look at your actual console output instead of the build scan, that you then see the properly encoded output. ---

Thank you for your answer, but it’s not just in scan, the console output also has the same error. ---

Try executing the JavaDoc command itself in the console and see whether it still has the same issue, then Gradle is out of the loop. Maybe you need a different Java, or maybe your console is configured wrongly. As a work-around you could probably set your locale to English to get English messages. ---

Thank you, after change the system language to English there are no more error log.Already solved the javadoc error
