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

解决办法:
pom.xml中增加插件
- <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
