1.pom.xml文件报Plugin execution not covered by lifecycle configuration: org.apache.maven.plugins:maven-resources-plugin:2.2:resources (execution: default-resources, phase: process-resources) pom.xml /testMaven-common line 3 Maven Project Build Lifecycle Mapping Problem
2.导致此错误是m2eclipse插件0.12及之前的版本在Eclipse 内执行了一系列的生命周期引起冲突导致的，如果你的maven报此类错误，而又用到了maven-resources-plugin这个插件，那么请按你的项目pom.xml中加上
<plugin>
<groupId>org.eclipse.m2e</groupId>
<artifactId>lifecycle-mapping</artifactId>
<version>1.0.0</version>
<configuration>
<lifecycleMappingMetadata>
<pluginExecutions>
<pluginExecution>
<pluginExecutionFilter>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<versionRange>[1.2,)</versionRange>
<goals>
<goal>resources</goal>
<goal>testResources</goal>
</goals>
</pluginExecutionFilter>
<action>
<ignore />
</action>
</pluginExecution>
</pluginExecutions>
</lifecycleMappingMetadata>
</configuration>
</plugin>
