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

 
 

<build>
  
  

<plugins>

  
  

<plugin>

  
  

<artifactId> maven-assembly-plugin </artifactId>

  
  

<configuration>

  
  

<descriptorRefs>

  
  

<descriptorRef>jar-with-dependencies</descriptorRef>

  
  

</descriptorRefs>

  
  

<archive>

  
  

<manifest>

  
  

<mainClass></mainClass>

  
  

</manifest>

  
  

</archive>

  
  

</configuration>

  
  

<executions>

  
  

<execution>

  
  

<id>make-assembly</id>

  
  

<phase>package</phase>

  
  

<goals>

  
  

<goal>assembly</goal>

  
  

</goals>

  
  

</execution>

  
  

</executions>

  
  

</plugin>

  
  

</plugins>

  
  
</build>
 
 

 完整的pom.xml文件配置如下：

 
 


<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

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。
