Resolving jar packages in the Web-inf/lib directory cannot be packaged with Maven

Part of the jar package in the project is based on the Pom file dependency, part of the BuildPath into the Web-inf/lib directory, and finally when using MAVEN packaging, found unable to put the jar package Web-inf/lib under the war package, The class that introduced the jar in the Web-inf/lib directory could not be compiled with an error.

How to resolve:

Add the following Maven plugin to the Pom file:

<build>
    <plugins>
      <plugin>
        <artifactid>maven-compiler-plugin</ artifactid>
        <configuration>
          <source>1.7</source>
          <target>1.7</target >
          <encoding>UTF-8</encoding>
               <compilerArguments>
                  <!--<extdirs>${ Basedir}/webroot/web-inf/lib</extdirs>-
                   <extdirs>${basedir}/src/main/webapp/web-inf/lib </extdirs>
               </compilerArguments>
        </configuration>
      </plugin>
    </ Plugins>
  </build>

After adding this code, re-use MAVEN to package the compilation can be in the Web-inf/lib directory of Jar package and Pom file dependent jar package into the war package.
