如何使用Wildfly Swarm为io.swagger.jaxrs.listing.SwaggerSerializers类解决WELD-001318？

Question

我将Wildfly Swarm 2017.12.1添加到我的pom中。我没有手动添加分数，因为所有的分数都是自动发现的：

摆动分数是不稳定的。我不知道为什么，但不管怎样。它被添加了，后来我得到了一些错误。我得到的错误消息是：

2018-01-03 14:37:46,545 ERROR [org.jboss.msc.service.fail] (ServerService Thread Pool -- 11) MSC000001: Failed to start service jboss.undertow.deployment.default-server.default-host./: org.jboss.msc.service.StartException in service jboss.undertow.deployment.default-server.default-host./: java.lang.RuntimeException: RESTEASY003945: Unable to instantiate MessageBodyWriter
        .... long stacktrace ...

  - Managed Bean [class io.swagger.jaxrs.listing.SwaggerSerializers] with qualifiers [@Any @Default]
        ... stacktrace...

正如你所看到的，它在类路径中找到了两次SwaggerSerializers，所以我猜这是Swarm安装swagger片段的问题。也许，如果我手动添加所有依赖项，而不使用swagger，它可能会起作用。但我不认为这是一个好的解决方案。正如在https://issues.jboss.org/browse/SWARM-271中所指出的，这是一个错误。

有没有办法解决这个问题？

我找到了解决方案。我只需在项目的pom中将<scope>provided</scope>添加到swagger的依赖项中。
