maven 项目 pom.xml 出错

1,missing ***.jar
那就添加 dependency

2,报：
Plugin execution not covered by lifecycle configuration:
org.apache.maven.plugins:maven-antrun-plugin:1.3:run (execution: default, phase: compile)
错误信息格式为 groupId:artifactId:version:goal

在</plugins>后添加

<pluginManagement>
			<plugins>
				<!--This plugin's configuration is used to store Eclipse m2e settings 
					only. It has no influence on the Maven build itself. -->
