严重: ContainerBase.addChild: start: java.lang.NoClassDefFoundError: Lorg/apache/log4j/Logger

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>1.2.14</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;

解决右键点击项目选择Properties：
