뭐 대충 이러한 에러인데 해결방법은 의외로 간단하다. 

 

pom.xml

<plugins>
  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.8.0</version>
    <configuration>
      <forceJavacCompilerUse>true</forceJavacCompilerUse>
      <source>${java.version}</source>
      <target>${java.version}</target>
      <compilerVersion>${java.version}</compilerVersion>
      <encoding>${encoding}</encoding>
    </configuration>
    ...후략...

 

위처럼 compiler 설정부분에 <forceJavacCompilerUse>true</forceJavacCompilerUse> 를 추가해 넣어주면 된다.
