eclipse pom.xml 报错org.apache.maven.plugin.war.WarMojo的解决办法

如题，maven项目eclipse提示pom.ml有错，提示信息就是org.apache.maven.plugin.war.WarMojo。

然后执行 maven install 出现如下错误提示

1. [INFO] --- maven-war-plugin:2.2:war (default-war) @ ams-web ---
2. [WARNING] Error injecting: org.apache.maven.plugin.war.WarMojo

解决办法：

pom.xml中增加插件

1. <plugin>
2. <groupId>org.apache.maven.plugins</groupId>
3. <artifactId>maven-war-plugin</artifactId>
4. <version>3.0.0</version>
5. </plugin>

                <plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-war-plugin</artifactId>
                    <version>3.0.0</version>
                </plugin>

原本是没有设置这个插件，maven 应该自动使用了2.2版本的，换成3.0.0后，不在报这个错。为什么是3.0.0，我找了下我的本地仓库，有这个版本的，所以就没有尝试其他版本了。

猜测：这个项目以前是没有这个错误的，我更换本地的开发环境后，才出现的，以前是 JDK7 + myeclipse2014，后来我换成了JDK8 + eclipse 4.4了，IDE里面都是自己下载的同一个maven 3.2.5，所以我觉得应该是JDK版本和maven插件冲突了
