高枕无忧。 Class 未找到定义

Question

我正在使用 resteasy 和 wildfly 构建 rest-client。根据 stacktrace，我可能遇到了依赖问题。
已经做了很多关于更改范围的尝试，在 pom.xml 中删除或添加依赖项没有给出任何结果，除了另一个未找到的堆栈跟踪...
这是我的

根据堆栈跟踪，您是运行 IntelliJ 中的主要方法。

您所有的 RESTEasy 依赖项都标记为 'provided'。这意味着应用程序期望运行时容器（例如应用程序服务器）提供它们。 IntelliJ 本身不会在运行时提供这些依赖项，因此您会收到 ClassNotFoundException 错误。

https://maven.apache.org/guides/introduction/introduction-to-dependency-mechanism.html

provided

This is much like compile, but indicates you expect the JDK or a container to provide the dependency at runtime. For example, when building a web application for the Java Enterprise Edition, you would set the dependency on the Servlet API and related Java EE APIs to scope provided because the web container provides those classes. This scope is only available on the compilation and test classpath, and is not transitive.

要在 IntelliJ 中测试应用程序，只需删除提供的范围。
