maven中把依赖的JAR包一起打包

一、scope要修改为runtime

特别注意<scope>provided</scope>，只在编译的classpath中加载和使用，打包的时候不会包含在目标包中。 

所以如果想把该依赖包也一起打包，那么应该改成<scope>runtime</scope>。

具体可以参考：MAVEN Scope使用

二、在pom.xml中添加maven-assembly-plugin插件

1. <build>
2. <plugins>
3. <plugin>
4. <artifactId> maven-assembly-plugin </artifactId>
5. <configuration>
6. <descriptorRefs>
7. <descriptorRef>jar-with-dependencies</descriptorRef>
8. </descriptorRefs>
9. <archive>
10. <manifest>
11. <mainClass></mainClass>
12. </manifest>
13. </archive>
14. </configuration>
15. <executions>
16. <execution>
17. <id>make-assembly</id>
18. <phase>package</phase>
19. <goals>
20. <goal>assembly</goal>
21. </goals>
22. </execution>
23. </executions>
24. </plugin>
25. </plugins>
26. </build>

 完整的pom.xml文件配置如下：

1. <projectxmlns="http://maven.apache.org/POM/4.0.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
2. xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

右键Maven-----》Update Project：

右键Run As ----》Maven install

查看target目录，可以发现多了XXXXX--jar-with-dependencies.jar

由于该jar包把所有的依赖包也打包进去了，所以会变得非常大。
