        java.lang.IllegalStateException: The Java Virtual Machine has not been configured to use the desired default character encoding (UTF-8).

It can be fixed like: add Environment variable JAVA_TOOL_OPTION = -Dfile.encoding="UTF-8"but it don't works.

Environment variable

In IntelliJ Idea Settings everything is set to UTF-8.

aplication.properties

spring.mandatory-file-encoding=UTF-8

pom.xml

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
    <file.encoding>UTF-8</file.encoding>
    <java.version>1.8</java.version>
</properties>

We can encode the source encoding and output encoding by passing runtime arguments to command as follows:

mvn -Dproject.build.sourceEncoding=UTF-8 -Dproject.reporting.outputEncoding=UTF-8 clean deploy 

Or by adding line in pom.xml:

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <redis.version>1.3.5.RELEASE</redis.version>
</properties>
