创建 CXF web 服务客户端时出现 ServiceConstructionException (scala+java+wsdl2java)

Question

这些其他问题暗示了一个解决方案，但我无法让它发挥作用：

当我通过执行 java -Xdebug -jar myapp.jar 启动我的应用程序时，当应用程序进行 SOAP 调用时，我得到一个 ServiceConstructionException: Could not resolve a binding for null。当我在 IntelliJ 中启动应用程序时，应用程序和 SOAP 调用工作正常。这是重现错误的最小示例：https://github.com/stianlagstad/mainclass-and-jxf-problems-demo

重现步骤：
- gradle clean build && java -Xdebug -jar build/libs/mainclass-and-jxf-problems-demo.jar
- 转到 http://localhost:4242/endpoint/ 并查看错误

谁能帮我弄清楚我必须做哪些更改才能使 SOAP 调用正常工作？

编辑以提供更多信息：

如果我编辑 build.gradle 以不排除 META-INF（即使用 configurations.compile.collect { it.isDirectory() ? it : zipTree(it) } 而不是 configurations.compile.collect { it.isDirectory() ? it : zipTree(it).matching{exclude{it.path.contains('META-INF')}} }），我会收到此错误：Error: Could not find or load main class com.shadowjarcxfproblem.JettyLauncher（当启动应用程序作为一个罐子）。然而，在 IntelliJ 中启动应用程序仍然有效，并且 SOAP 调用也有效。

在阅读了这两本书并尝试了很多不同的东西之后，我终于偶然发现了一些有用的东西！

https://discuss.gradle.org/t/how-do-i-use-the-gradle-shadow-plugin-to-merge-spring-handlers-and-spring-schemas-files-of-multiple-spring-jar-dependencies/6713/6

使用 gradle shadowjar 插件解决了这个问题：

import com.github.jengelman.gradle.plugins.shadow.transformers.ServiceFileTransformer
shadowJar {
    // Make sure the cxf service files are handled correctly so that the SOAP services work.
    // Ref 
    transform(ServiceFileTransformer) {
        path = 'META-INF/cxf'
        include 'bus-extensions.txt'
    }
}
