Plugins 如何安装maven jdocbook插件？

我想编译netty，但当我运行

mvn install

时，它会报告以下错误：

[INFO] ------------------------------------------------------------------------
[INFO] Building The Netty Project 4.0.0.Alpha1-SNAPSHOT
[INFO] ------------------------------------------------------------------------
[WARNING] The POM for org.jboss.maven.plugins:maven-jdocbook-plugin:jar:2.2.1 is missing, no dependency information available
[INFO] ------------------------------------------------------------------------
[INFO] BUILD FAILURE
[INFO] ------------------------------------------------------------------------

我找到了的文档，但找不到安装它的方法。我的maven环境是：

E:\WORKSPACE_SCALA\netty>mvn --version
Apache Maven 3.0.3 (r1075438; 2011-03-01 01:31:09+0800)

如何安装此插件？

插件的pom丢失，您应该尝试将JBoss插件库添加到pom.xml中（在标记之前）：

JBoss回购
https://repository.jboss.org/nexus/content/repositories/releases
JBoss回购

您可能还需要将其添加到您的工件存储库中：

 <repositories>
   <repository>
     <id>JBoss Repo</id>
     <url>https://repository.jboss.org/nexus/content/repositories/releases</url>
     <name>JBoss Repo</name>
   </repository>
 </repositories>

JBoss回购
https://repository.jboss.org/nexus/content/repositories/releases
JBoss回购

正确的回购协议现在是

 <repositories>
   <repository>
     <id>JBoss Repo</id>
     <url>https://repository.jboss.org/nexus/content/repositories/releases</url>
     <name>JBoss Repo</name>
   </repository>
 </repositories>
