원인

• resources 밑에 mwb 파일을 넣어둬서 그런거였다.
• properties 에 한글이 있거나, UTF-8로 변경하는건 도움이 되지 않았다.

해결

• pom.xml 에 아래와 같이 추가해줌

<build>
  <plugins>
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-resources-plugin</artifactId>
      <version>3.2.0</version>
      <configuration>
        <propertiesEncoding>UTF-8</propertiesEncoding>
        <nonFilteredFileExtensions>
          <nonFilteredFileExtension>mwb</nonFilteredFileExtension>
        </nonFilteredFileExtensions>
      </configuration>
    </plugin>
  </plugins>
