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"
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。
