“illegal character” error when using hibernate-jpamodelgen in Spring Boot

  <dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-jpamodelgen</artifactId>
    <version>${hibernate.version}</version>
  </dependency>

When I add the above dependency and compile my project, I get an “illegal character” error for Turkish characters. My problem is same as here but I didn’t understand how to solve it in Spring Boot. I tried the solutions but they didn’t work.

I would be glad if you help.

Answer

Days later I tackled the issue again and finally resolved it. I have two different solutions for the following two different situations.

1) Using maven wrapper (mvnw)

• Create .mvn/jvm.config file in the project.
• Add the following options to file.

-Duser.language=en
-Duser.country=US

2) Using Intellij Idea

• Add the same options above to the .vmoptions file described here.
• Select File -> Invalidate Caches -> Invalidate and Restart
