How do I set the encoding for Javadoc in the gradient?

I've written Java classes with the Javadoc command, which contains special characters like ä ö ü I use gradle build file to generate Javadoc:

apply plugin: 'java'

And on the command line: gradle Javadoc

The encoding of the original document is UTF-8 The encoding of Javadoc file is also UTF-8 But there is no prompt in the HTML source code. The file is UTF-8 That's why my browser always thinks it's ISO-8859

How to tell Javadoc (through gradle) to add < meta charset = "UTF-8" / > to the source code when generating Javadoc?

Solution

You will need to set Javadoc charset option

javadoc {
    options.charSet = 'UTF-8'
}
