Arya03（Tomcat运行失败的问题）

这是eclipse中Tomcat崩溃时的解法

问题：项目无法启动报错Removing obsolete files from server… Could not clean server 。。。。

用了百度上的各种方法都没用

• 首先尝试了把Tomcat删除后再重新建立，然而没用
• 第二个方法是保证eclipse中tomcat的server.xml与Tomcat根目录下conf/server.xml保持一直，然后删除eclipse的Workspace工作目录下的.metadata.pl ugins\org.eclipse.wst.server.core中temp0文件夹中所有文件，然而对我的项目依旧没用，这时候以及很崩溃了。。。。。

• 最后我又看到网上是说eclipse的版本和Tomcat版本不匹配？？但是之前为毛可以运行我很怀疑？于是我把Tomcat原来的7.0版本换成了6.0，总算是有点用了。亲测最好用的方法还是把EClipse那个大头文件删了重新装最好办哈哈哈。

• Tomcat编译时报错

  可以试试clean一下项目再重新发布，如果没用就去看看配置文件，配置文件肯定有错误了。
