原因： 使用的版本是maven3.X,其執行maven-ant-plugin的行為和maven2.x有一定的不同，需要引入pluginManagement
解決辦法是：在pom.xml中引入：
之前的內容：
<build>
<plugins>
<plugin></plugin>
...
<plugin></plugin>
</plugins>
</build>
修改后的內容：
<build>
<pluginManagement>
<plugins>
<plugin></plugin>
...
<plugin></plugin>
</plugins>
</pluginManagement>
</build>
