Maven을 시작하면서 해결할 수없는 문제가 발생했습니다. 내 응용 프로그램을 실행하는 데 필요한 항아리 파일이 클래스 경로에없는 것 같습니다. maven 패키지 중에 Maven이 이것을 돌봐주지 않아야합니까? 내가 MVN 패키지를 실행하면포장 중에 classpath에 jar 파일을 포함하지 않음
, 내가 얻을 오류 :
[ERROR] /home/dev/Desktop/maventest/my-app/src/main/java/com/mycompany/app/App.java:[79,9] cannot find symbol
symbol: class UpnpService
location: class com.mycompany.app.App
[ERROR] /home/dev/Desktop/maventest/my-app/src/main/java/com/mycompany/app/App.java:[79,39] cannot find symbol
symbol: class UpnpServiceImpl
location: class com.mycompany.app.App
샘플 코드를 말하는가 : "당신은 집착-core.jar를하고 종속성이 필요 - 당신의 클래스 패스 (원활한 * jar 파일을.) 이 코드를 빌드하고 실행하십시오. "
그러나 이것은 메이븐이 처리해야하는 것이 아닙니까? 그렇지 않은 경우이 파일을 어떻게 포함합니까? 여기
내 pom.xml 파일입니다 :<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

예제 코드에서이다 당신의 도움을 주셔서 감사합니다.
이 또한 내 pom.xml 파일에없는 : – Jimbotron
