如何在Maven项目模块A引用子模块B的war项目的类文件?

1.首先在war模块B添加一个maven-jar-plugin，并设置其classifier为jar.

 1 <plugin>
 2     <groupId>org.apache.maven.plugins</groupId>
 3     <artifactId>maven-jar-plugin</artifactId>
 4     <version>2.4</version>
 5     <configuration>
 6         <classifier>jar</classifier>
 7     </configuration>
 8     <executions>
 9         <execution>
10             <goals>
11                 <goal>jar</goal>
12             </goals>
13         </execution>
14     </executions>
15 </plugin>

2.然后模块A引用模块B的jar文件

1 <dependency>
2     <groupId>${project.groupId}</groupId>
3     <artifactId>B</artifactId>
4     <version>${project.version}</version>
5     <classifier>jar</classifier>
6     <scope>runtime</scope>
7 </dependency>
