Maven简单方式将所有依赖打包到一个jar

用如下插件

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-assembly-plugin</artifactId>
    <version>2.6</version>
    <configuration>
        <descriptorRefs>
            <descriptorRef>jar-with-dependencies</descriptorRef>
        </descriptorRefs>
        <archive>
            <manifest>
                <addClasspath>true</addClasspath>
                <mainClass>com.ch.Main</mainClass>
            </manifest>
        </archive>
    </configuration>
</plugin>

运行命令

clean compile assembly:assembly

搞定！
