当我启动 mvn wildfly:deploy 时出现错误。

引用类 io/undertow/UndertowOptions 的类加载器（org/jboss/modules/ModuleClassLoader 的实例）和字段解析类型 org/xnio/ 的类加载器（org/jboss/modules/ModuleClassLoader 的实例）选项，该类型有不同的类对象[错误] 原因：org.springframework.beans.factory.BeanCreationException：创建类路径资源中定义的名称为“undertowServletWebServerFactory”的bean时出错[org/springframework/boot/autoconfigure/web/servlet /ServletWebServerFactoryConfiguration$EmbeddedUndertow.class]：bean 初始化失败；嵌套异常是 java.lang.LinkageError：加载器约束违规：当解析字段“MAX_HEADER_SIZE”时，引用类 io/undertow/UndertowOptions 的类加载器（org/jboss/modules/ModuleClassLoader 的实例），

据我了解，原因是依赖关系。如何解决？

原来是和插件拉取的库有冲突

<dependency>
    <groupId>org.wildfly.plugins</groupId>
    <artifactId>wildfly-maven-plugin</artifactId>
    <version>2.0.2.Final</version>
    <exclusions>
        <exclusion>
            <groupId>org.jboss.xnio</groupId>
            <artifactId>xnio-api</artifactId>
        </exclusion>
    </exclusions>
</dependency>
