In my case I resolved that problem by setting new environment variable:

JAVA_TOOL_OPTIONS=-Dfile.encoding=UTF-8

In the command line executing maven, run current command before executing maven command:

SET JAVA_TOOL_OPTIONS=-Dfile.encoding=UTF-8

This is interesting, as your pom.xml mentions

<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

.. but the error message complains about Cp1251 encoding. Does the maven output mention anything else related to source encodings?

My recommendation is generally to not use any high-ASCII characters in your code, and use the \uxxxx notation instead as needed.

You can make the conversion from UTF-8 to escaped unicode at online conversion sites like http://www.endmemo.com/convert/EMUnicode.php (this particular one seems to strip leading zeroes, I don't think that's legal in Java)

You have characters in that file which are likely not mapped in the Windows codepage (which is the reference to Cp1251). Try changing the project encoding to UTF-8 or similar. Look into different encoding schemes.
