在Jenkins中利用Gradle编译项目时，可能会出现以下错误

码农不是在报错的路上，就是在调错的路上，这也许是上天的“眷顾”，今天运行在myeclipse关联Tomcat出错了：

Tomcat7早就出来正式版，但是一直都没有用过，尤其是针对于我还一直在用Myeclipse6.5的人来说，它在配置<em>tomcat</em>的时候没有<em>tomcat</em>7的选项，所以就报了错误信息。
java.lang.NoClassDefFoundError: org/apache/juli/logging/LogFactory
at org.apache.catalina.startup.
用命令
ps -ef|grep <em>tomcat</em>
查看没有<em>tomcat</em>进程。
查看<em>tomcat</em><em>日志</em>信息，出现了下面的错误：
WARNING: error instantiating 'org.apache.juli.ClassLoaderLogManager' referenced by java.util.logging.manager, class not found
> windows环境下启动Tomcat，<em>日志</em>只在文件中有，控制台中什么都不显示，我使用的是原生的<em>tomcat</em> 7.0.59，<em>tomcat</em>中没用log4j，但项目中用了log4j2
另外问一下start.bat最后一行`call "%EXECUTABLE%" start %CMD_LINE_ARGS%`改成`call "%EXECUTABLE%" run %CMD_LINE_ARGS%`是什么意思，麻烦详细说说，谢谢
下面是<em>tomcat</em>中`logging.properties`配置(没改过)
