maven管理的项目,里面已经引入了log4j的包

maven引入如下:



<dependency>
      <groupId>log4j</groupId>
      <artifactId>log4j</artifactId>
      <version>1.2.16</version>
      <scope>compile</scope>
 </dependency>


但还是报

Caused by: org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[]]

at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:154)

... 6 more

Caused by: java.lang.NoClassDefFoundError: Lorg/apache/log4j/Logger;

看了下tomcat项目中lib 下,maven的包没有到过来,感觉很奇怪.昨天项目还是OK的

修改如下:

Maven项目java.lang.NoClassDefFoundError: Lorg/apache/log4j/Logger报错_apache

add中选择

Maven项目java.lang.NoClassDefFoundError: Lorg/apache/log4j/Logger报错_apache_02

问题搞定
