Question

这些其他问题暗示了一个解决方案，但我还没有能够解决这个问题：
Could not resolve a binding for http://schemas.xmlsoap.org/wsdl/soap/
ServiceConstructionException when creating a CXF web service client
How to package an Apache CXF application into a monolithic JAR with the Maven "shade" plugin

当我通过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。以下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

任何人都可以帮我弄清楚我必须做些哪些改变才能使SOAP调用工作？

编辑以提供更多信息：

如果我修改build.gradle以不排除META-INF（即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（在启动应用时一个罐子）。然而，在IntelliJ中启动应用程序仍然有效，然后SOAP调用也可以正常工作。

在读完这两个并尝试了一堆不同的东西后，我终于偶然发现了一些有用的东西！ How to package an Apache CXF application into a monolithic JAR with the Maven "shade" plugin
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插件完成此任务解决了问题：

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 https://stackoverflow.com/questions/45005287/serviceconstructionexception-when-creating-a-cxf-web-service-client-scalajava
    transform(ServiceFileTransformer) {
        path = 'META-INF/cxf'
        include 'bus-extensions.txt'
    }
}
