我有一个grpc的micronaut项目，还有一个gradle任务，用于从wsdl生成Java类。 构建成功，但是当我启动grpc服务器并调用使用生成的类之一的方法时，出现以下错误：

Caused by: java.lang.NullPointerException: null
at org.apache.cxf.wsdl11.WSDLServiceFactory.<init>(WSDLServiceFactory.java:85)
at org.apache.cxf.jaxws.ServiceImpl.initializePorts(ServiceImpl.java:218)

这是我的build.gradle

有帮助吗？
