如題，maven專案eclipse提示pom.ml有錯，提示資訊就是org.apache.maven.plugin.war.WarMojo。
然後執行 maven install 出現如下錯誤提示

解決辦法：
pom.xml中增加外掛
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>3.0.0</version>
</plugin>原本是沒有設定這個外掛，maven 應該自動使用了2.2版本的，換成3.0.0後，不在報這個錯。為什麼是3.0.0，我找了下我的本地倉庫，有這個版本的，所以就沒有嘗試其他版本了。
猜測：這個專案以前是沒有這個錯誤的，我更換本地的開發環境後，才出現的，以前是 JDK7 + myeclipse2014，後來我換成了JDK8 + eclipse 4.4了，IDE裡面都是自己下載的同一個maven 3.2.5，所以我覺得應該是JDK版本和maven外掛衝突了
