Question

您好我继续收到此错误消息

 A required class was missing while executing org.eclipse.jetty:jetty-maven-plugin:9.2.3.v20140905:run: javax/ws/rs/client/RxInvokerProvider

我试图删除maven repo所以它被迫下载库agian但没有结果。如果我手动添加这种依赖关系，它就会抱怨另一件事情，等等，这让我觉得别的东西导致了这种情况。

任何人都有任何线索？这是我的pom.xml以及

此项目一直在运作，但现在它不再启动了。

这是maven依赖树

Answer 1

javax.ws.rs.client.RxInvokerProvider是在JAX RS API 2.1中引入的

然而你的依赖树有......

[INFO] |  \- javax.ws.rs:javax.ws.rs-api:jar:2.0.1:compile

你的依赖性很差。

Answer 2

每当遇到“此项目一直在运作但现在它不再启动它了。”你需要弄清楚项目破坏时发生的变化。为此，您需要源代码控制（如git，mercurial或bazaar）。检查提交，直到找到提交之前的工作，而不是之后。然后看看发生了什么变化。

如果您使用git，那么git bisect可能会有所帮助。有关如何执行此操作，请参阅https://git-scm.com/book/en/v2/Git-Tools-Debugging-with-Git#_binary_search。

如果您不使用源代码管理，现在是重新考虑的好时机。

执行org.eclipse.jetty时缺少必需的类：jetty-maven-plugin：9.2.3.v20140905：run：javax / ws / rs / client / RxInvokerProvider
