Question

我将一个存在的maven项目导入Intellij idea ultimate2017.2，并添加一个tomcat本地服务器，但是当我运行该项目时，会发生错误：

我正在使用tomcat8.5.16，maven3.5.0，而slf4j中的pom.xml依赖关系是：

<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-api</artifactId>
    <version>${slf4j.version}</version>
</dependency>
<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>log4j-over-slf4j</artifactId>
    <version>${slf4j.version}</version>
    <scope>runtime</scope>
</dependency>
<dependency>

    <artifactId>jul-to-slf4j</artifactId>

</dependency>

intellij会自动将maven依赖项添加到web lib中吗？我找不到lib中的webapp/WEB_INF目录，以及如何将maven库添加到webapp中？

应该使用mvn命令来构建项目。打开Run/Debug Configuration - ＆gt;选择您创建的Tomcat Server - ＆gt; Before launch:Maven Goal,Build Artifacts,Activate tool window - ＆gt;点击+并使用maven clean package

在Intellij idea ultimate2017.2中运行maven webapp时出错：引起：java.lang.NoClassDefFoundError：Lorg / slf4j / Logger
