当一个新的maven项目导入到新的工作空间中可能会遇到maven插件lifecycle configuration 错误，这个错误可能是某个插件冲突，这个我还没没有太明白太搞懂，如果有人知道具体是什么原因引起的还请解释一下。
这个错误我在官网上面找到解决方案如下：
在eclipse 中找到 window > preferences > Maven > Lifecycle Mappings
进入到change mapping file location 的目录下 找到一个 lifecycle-mapping-metadata.xml 文件如果没有的话可以创建一个
然后加入一下这段代码
<?xml version="1.0" encoding="UTF-8"?>
<lifecycleMappingMetadata>
<pluginExecutions>
<pluginExecution>
<pluginExecutionFilter>
<groupId>org.codehaus.mojo</groupId>
<artifactId>buildnumber-maven-plugin</artifactId>
<goals>
<goal>create-timestamp</goal>
</goals>
<versionRange>[0.0,)</versionRange>
</pluginExecutionFilter>
<action>
<ignore />
</action>
</pluginExecution>
<pluginExecution>
<pluginExecutionFilter>

</pluginExecution>
</pluginExecutions>
</lifecycleMappingMetadata>
配置好后可以 maven -> update project 就可以看到错误已经没有了。
