Maven Ubuntu 12.04，Tomcat7，NetBeans 7-获取java.lang.NoClassDefFoundError:Lorg/slf4j/Logger；

我有一个JavaEE项目，它在一个使用tomcat容器的远程服务器上运行良好。每当我们想要对应用程序进行一些更改时，我们都会在本地机器上进行更改，然后构建它并将

ws.war

复制到tomcat根目录下的服务器上

我想设置本地开发环境，在那里我可以对应用程序进行更改。我随身带着项目源文件。我做了以下几件事：

 1. Install tomcat7 in my home directory and set up `CATALINA_HOME`
    environment variable in `.bashrc`
 2. Install oracle-java and setup JAVA_HOME in `.bashrc`
 3. Install Netbeans 7 and import the project in it.
 4. Since, the Netbeans came with `glassfish` as default server, I added
    a tomcat as the server with proper configuration.
 5. I try running the application (through Netbeans), and I receive the following error:

我做了一些研究，发现1.6.1版本和以前版本的

slf4j

存在一些版本不兼容。但是，我找不到解决方法

感谢您的帮助。我的POM.xml如下所示：

首先，有点奇怪，您有sl4fj-log4j12，但没有实际的log4j依赖项本身。通常您需要这样做，因为sl4fj只是一个门面。尝试添加以下内容：

<dependency>
    <groupId>log4j</groupId>
    <artifactId>log4j</artifactId>
    <version>1.2.17</version>
</dependency>

log4j
log4j
1.2.17

---

其次，您可能希望检查生产服务器中$TOMCAT_HOME/lib文件夹中的内容。如果有任何附加JAR放置在默认JAR之上，您也需要将其复制到您的本地环境中（或重组部署，使所有内容都包含在您的应用程序中）

好的，我会尝试一下，并让您知道。现在，我得到。。。原因：java.lang.NoClassDefFoundError:Lorg/slf4j/Logger；声明对org.slf4j:slf4j-log4j12的依赖关系将引入org.slf4j:slf4j api以及log4j:log4j。因此，通常不需要单独声明org.slf4j:slf4j api或log4j:log4j。您可以为您的项目发布“mvn dependency:tree”命令的内容吗？
