저는 Eclipse에서 지난 6 개월 동안 Google App Engine에서 작업 해 왔지만, Android Studio를 많이 사용하기 때문에 IntelliJ를 사용하려고합니다.IntelliJ로 Maven에서 ClassNotFoundException이 발생했습니다.
그래서 학습용으로 테스트 응용 프로그램을 만들었으므로이 오류가 발생했습니다. (https://pastebin.com/YgB0j6TW)
내가 시작한 방법은 App Engine 프로젝트를 만든 다음, "프레임 워크 지원 추가 ..."로 추가하는 것입니다. Maven을 추가하기 전에 오류를 추가하지 않습니다.
오류로 보이는 종속성은 다음과 같습니다.

이클립스에서와 마찬가지로 jersey 서블릿을 선언했습니다.

나는 모든 가져 오기의 범위를 확인했으며 "컴파일"로 설정되어 있습니다. 나는 일식에서했던 것처럼 저지 서블릿을 선언했습니다.
나는 이것이 내가 여기에 해결책을 chencking하여 잘못된 것을 발견하지 못한 클래스 경로 선언과 관련이 있다고 생각한다.
