我如何将Maven Jar项目添加到Maven War项目中？

Question

我有一个用于静态链接到其他jar文件的Eclipse java / jar项目。 我将该项目重新制作为一个maven项目（清单1），因此我可以删除这些静态jar文件并让maven解决它们。 而且我有另一个战争Web应用程序，我还转换了另一个项目MyWarProject，该项目以前将MyJarProject依赖为maven。 并添加了MyJarProject作为依赖项（清单2）。

这是我的jar项目的上半部分pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <groupId>MyJarProject</groupId>
    <artifactId>MyJarProject</artifactId>
    <packaging>jar</packaging>
    <version>0.0.1-SNAPSHOT</version>


  <build>
    <plugins>
     <plugin>
       <groupId>org.apache.maven.plugins</groupId>
       <artifactId>maven-jar-plugin</artifactId>
       <executions>
         <execution>
           <goals>
             <goal>jar</goal>
           </goals>
         </execution>
       </executions>
     </plugin>
    </plugins>
  </build>

    <dependencies>......

这是战争项目的完整清单pom.xml，它取决于jar文件

        </plugin>
      </plugins>
    </build>

  </project>

在进行Maven全新安装后，第一个jar项目会生成良好。 但是，战争项目会显示此错误消息。 那些缺少的类（如ItemsDAO）应该从jar项目中解决。 实际上，没有任何jar文件被复制到WEB-INF文件夹。 请帮忙！
