Question

我尝试通过终端执行swagger.json来生成mvn exec:java -DGetSwaggerDoc，然后按照＆＃34;生成OpenAPI配置规范＆＃34; https://cloud.google.com/endpoints/docs/frameworks/java/quickstart-frameworks-java的部分。这就是我得到的：

这是我的appengine-web.xml：

我正在使用Endpoints Framework 2.0.0-beta.9。我该如何解决这个问题？

mvn exec：java -DGetSwaggerDoc抛出java.lang.NoSuchFieldError：WHITESPACE
