Drools 5.4.0.Final Java 8에서 실행할 수 없습니다.

Question

Caused by: java.lang.RuntimeException: The Eclipse JDT Core jar is not in the classpath 

클래스를 빌드 할 때 위의 오류가 발생합니다. 나는 Drools 5.4.0.Final를 사용하고 난 수동으로 빌드 경로에 ecj-4.5.1.jar을 추가 한하지만 여전히 말한다 :

JDT 코어 클래스가 아닌 경로에.

내가 Eclipse Mars, Jdk 1.8, drools 5.4.0.Final

사람이 솔루션을 제안 할 수를 사용하고

?

편집 : (스택 트레이스 추가) 내가 ECJ-4.5.1.jar를 추가 한 후 문제가 해결 된

Answer 1

. 문제는 ecj jar가 프로젝트와 동일한 클래스 경로에 있어야한다는 것입니다. jar의 클래스 경로가 다른 경우 ecj jar를 라이브러리 폴더 자체에 추가하면 작동하지 않습니다.
