해결책1
- pom.xml에 컴파일러관련 의존성 추가
<dependency>
<groupId>org.eclipse.jdt.core.compiler</groupId>
<artifactId>ecj</artifactId>
<version>4.6.1</version>
</dependency>
참고
문제2
- 이클립스에서의 문제는 해결했으나 war로 배포시 문제 발생
Exception in thread "main" java.lang.IllegalStateException: Failed to get nested archive for entry WEB-INF/lib/ecj-3.18.0.jar- 이전에 따로 추가한 ecj는 버전이 4.6.1인데 반해 3.18.0버전과 관련하여 문제 발생
해결책2
- 3.18.0을 빌드시 제외시킴
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
<exclusions>
<exclusion>
<groupId>org.eclipse.jdt</groupId>
<artifactId>ecj</artifactId>
</exclusion>
</exclusions>
</dependency>maven clean 후 다시 빌드 및 패키징하하여 실행하면 정상 작동
