libgdx 소스 코드를 빌드 오류가 나는 Libgdx 소스 코드를 설정하는 데 문제 유형

Question

에 해결할 수없는, 내가 다음에 한 두 가지 설정 가이드 : 난을 다운로드 한 https://github.com/libgdx/libgdx/wiki/Setting-up-your-Development-Environment-%28Eclipse%2C-Intellij-IDEA%2C-NetBeans%29

https://github.com/libgdx/libgdx/wiki/Running-demos-%26-tests

소스, 최신 버전의 JDK를 가지고 있고 안드로이드 SDK가 있고 안드로이드 SDK가 설치되어 있고 다른 모든 단계를 완료했습니다. (올바르게 알고있는 한) libgdx 설정에 수천 개의 오류가 있습니다. 청소 및 재건축. 오류는 모두 "유형으로 해결할 수 없습니다"라는 라인을 따라 있습니다. 아무도 내가 뭘 망쳤다는 걸 압니까?

또한 "ant"를 실행 해 보았습니다. 실행중인 데모 페이지에서 언급하는 것을 잊었으며 문제를 해결하지 못했습니다.

libgdx가 여전히 Java 7에있는 동안 Java 8 JDK를 사용할 수 있습니까?

Java 빌드 경로에 필수 .jars 파일을 추가 했습니까?

프로젝트 → 빌드 경로 → 빌드 경로 구성을 마우스 오른쪽 단추로 클릭하여 필요한 jars를 Eclipse에 추가하십시오. Libraries 탭에서 Jar 추가 또는 외부 JAR 추가를 클릭하고 Jar를 제공하십시오.
