IntelliJ Plugin 개발 : PluginException이 클래스를 생성 할 수 없습니다. 액션

Question

Builder 패턴을 생성하는 IntelliJ 플러그인을 작성 중입니다. 그러나 PluginException이라는 이유로 인해 플러그인을 사용할 수 없습니다. this post과 동일한 5 단계에서 오류를 재현했으며 거기에 답변이 게시되지 않았기 때문에이 질문에 몇 가지 코드 예제를 제공하기로 결정했습니다. (다른 질문에 대해서는 언급 할 수 없습니다. 너무).

코드는 here입니다. test-plugin은 현재 클래스의 getter 필드와 새로운 유형의 내부 클래스 (NumberFactory)를 생성해야합니다. 플러그인을 설치 한 후 얻는 stacktrace는 다음과 같습니다.

*cannot create class "be.koen.wellens.MyBuilderGeneratorAction" [Plugin: be.koen.wellens]: cannot create class "be.koen.wellens.MyBuilderGeneratorAction" [Plugin: be.koen.wellens] 
com.intellij.diagnostic.PluginException: cannot create class "be.koen.wellens.MyBuilderGeneratorAction" [Plugin: be.koen.wellens]

Answer 1

는 대답은 메오에 의해 주어졌다 (감사 메오!). 내가 한 일은 JDK 1.6을 사용하는 것뿐이었습니다. 인생의 모든 것들이 그렇게 단순하다면. :-)

다시 한 번 감사드립니다.
