java.lang.ClassNotFoundException：org.Eclipse.jetty.Server

Question

私はmvn installを実行するときにMavenプロジェクトを実行しようとしていますが、すべて問題ありません。

Exception in thread "main" Java.lang.ClassNotFoundException: org.Eclipse.jetty.Server at Java.net.URLClassLoader$1.run(URLClassLoader.Java:366) at Java.net.URLClassLoader$1.run(URLClassLoader.Java:355) at Java.security.AccessController.doPrivileged(Native Method) at Java.net.URLClassLoader.findClass(URLClassLoader.Java:354) at Java.lang.ClassLoader.loadClass(ClassLoader.Java:425) at Sun.misc.Launcher$AppClassLoader.loadClass(Launcher.Java:308) at Java.lang.ClassLoader.loadClass(ClassLoader.Java:358) at org.Eclipse.jetty.util.Loader.loadClass(Loader.Java:86) at org.Eclipse.jetty.xml.XmlConfiguration$JettyXmlConfiguration.nodeClass(XmlConfiguration.Java:364) at org.Eclipse.jetty.xml.XmlConfiguration$JettyXmlConfiguration.configure(XmlConfiguration.Java:292) at org.Eclipse.jetty.xml.XmlConfiguration.configure(XmlConfiguration.Java:248) at net.es.oscars.wbui.http.WebApp.main(WebApp.Java:44)

そして、mvn dependency：treeを実行すると、次の結果が得られました。

この問題を解決する方法はありますか!!!!

あなたのdependency:treeには、Jettyの古いバージョンがあります。

org.mortbay.jetty:jetty:jar:6.1.16:compile

それはうまくいきません。

JettyのEOL（End of Life）バージョン以来ずっと、その古いものを使用しないようにnet.es.oscars:utils:jarを修正する必要があります。

pom.xmlには、不安定なマイルストーンリリースへの参照があります

<dependency> <groupId>org.Eclipse.jetty</groupId> <artifactId>jetty-server</artifactId> <version>9.3.0.M0</version> </dependency>

Jettyの安定版バージョンを使用してください。

https://www.Eclipse.org/jetty/download.html を見て、安定しているものを確認します（マイルストーンリリースがそこにリストされていない）

主要な突堤バージョンの全体的なリストについては、突堤のドキュメントも参照してください。 https://www.Eclipse.org/jetty/documentation/current/what-jetty-version.html

この回答の時点での最新の安定リリースバージョンは9.4.18.v20190429です。

Java.lang.ClassNotFoundExceptionについては、まず依存関係を修正する必要があります。依存関係を修正しても問題が解決しない場合は、クラスローダーの作成方法とその階層、およびXmlConfigurationの使用方法（およびどのクラスローダーから）を投稿するか検討してください。
