我正在使用Eclipse靛蓝Service Release 2，安装了 JBoss 工具，并创建了一个选择了Maven集成的Seam Web项目。创建项目后，我在pom.xml文件中遇到了这个错误，有人知道如何解决这个错误吗？谢谢

Error resolving version for plugin 'org.codehaus.mojo:maven-war-plugin'
from the repositories [local (C:\Users\Jon\.m2\repository), 
jboss-public-repository-group 
(https://repository.jboss.org/nexus/content/groups/public/),
central (http://repo1.maven.org/maven2)]: 
Plugin not found in any plugin repository

我还尝试创建一个新的Seam web项目，再次与Maven集成，这是我遵循的步骤：http://docs.jboss.org/tools/nightly/trunk/en/seam/html/create_mavenized_seam.html#create_mavenized_project项目创建后，我在eclipse api中遇到这些错误，所有错误都与pom.xml有关（带有红色标志）

不知道为什么每次都出现不同错误，我使用的是Eclipse靛蓝新版本64big，下载位置：https://www.eclipse.org/downloads/packages/eclipse-ide-java-ee-developers/indigosr2和添加jboss工具从市场，与Jboss服务器和接缝famework.根据错误，我必须安装任何插件吗？这是如此混乱，因为我得到不同的错误每一次.
