我已經使用SLF4J + Logback替換了OSGi包的Java（1.8）應用程序中的JUL日誌記錄。但是，更換後，我可以再運行它（請參閱下面的錯誤）。我使用Maven Bundle插件（BND），但我不是OSGi的專家。在使用SLF4J的OSGi應用程序上的java.lang.LinkageError + Logback

關於依存關係：MYAPP取決於家長的應用程序，它依賴於SLF4J-API v1.7.12，番石榴V18，的logback-core和的logback經典V1.1.3。所以我沒有明確地在myapp的pom.xml中設置這些依賴關係。 myapp有另一個關鍵依賴項，它是koolapi;這個OSGi包在其/ lib /文件夾中包含slf4j-api-1.7.10.jar，但其清單中沒有Export-Package指令。
總的來說，我查看了所有包（felix，guava，logback-core，logback-classic，slf4j-api，koolapi，parent-app）的清單，以查看誰在使用/導出slf4j，並且只有logback-classic。 jar顯式導出org.slf4j.impl;版本= 1.7.7。
有沒有人有任何想法或建議如何解決衝突？
任何幫助將不勝感激！非常感謝， Joel
