似乎已解决问题。我不知道为什么，因为这些依赖项不在build.gradle文件中。
我将这个问题悬而未决，以便有人可以解释原因。
我正在尝试将build.gradle文件移植到pom.xml并运行mvn clean verify结果导致Failed to instantiate [org.eclipse.jetty.client.HttpClient]: Factory method 'httpClient' threw exception; nested exception is java.lang.InstantiationError: org.eclipse.jetty.util.SocketAddressResolver
当我尝试合并 Spring BOM 时，pom.xml有一些更改，但即使我从 gradle 生成的 pom 文件(由 gradle maven 插件生成)中获取依赖项，我仍然会收到相同的错误。
