The Gradle project is not published to the local Maven repository due to the fact that it uses Russian text in the source codes. How to fix it?

Question

Java

Hello. If I use Russian text in the program source codes (in comments or in button names, etc.), then the project is not published to the local maven repository. Errors of this kind:

C:\Users\...\IProfile.java:71: error: unmappable character for encoding Cp1251
visibleName = "Р?стория осмотров",

If you use Unicode codes instead of text in Russian, then everything works. How to make it work with pure readable Russian text? What should be written in build.gradle?
PS I do everything in IntelliJ IDEA. There are file encoding settings, and this is what I have selected there:

Also in build.gradle there is this line:

[compileJava, compileTestJava]*.options*.encoding = 'UTF-8'

Answer 1

You need to add the following to build.gradle:

tasks.withType(Javadoc) { options.encoding = 'UTF-8' }
