给同事提供一个sdk时，发现mvn install 构建的jar第三方包未下载下来，导致引入后找不到类；
解决方案：
1.
把依赖包和自己项目的文件打包如同一个jar包(这种方式对spring的项目不支持)
<build>
<plugins>
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<configuration>
<archive>
<manifest>
<mainClass>com.tang.CSVUtils</mainClass>
</manifest>
</archive>
<descriptorRefs>
<descriptorRef>
jar-with-dependencies
</descriptorRef>
</descriptorRefs>
</configuration>
<!-- 加上下面这一段,使用 mvn package命令,不加则使用mvn assembly-->
<!-- <executions>
<execution>
<id>make-assemble</id>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
</execution>
</executions> -->
</plugin>
</plugins>
</build>
2.mvn package(推荐)(一个zip包，里面有一个jar包，一个lib文件夹，和一个conf文件夹)
(1)conf/package.xml (conf 文件夹和pom.xml在同一级目录)
<assembly>
<id>bin</id>
<!-- 最终打包成一个用于发布的zip文件 -->
<formats>
<format>zip</format>
</formats>
<!-- Adds dependencies to zip package under lib directory -->
<dependencySets>
<dependencySet>
<!--
不使用项目的artifact，第三方jar不要解压，打包进zip文件的lib目录
-->
<useProjectArtifact>false</useProjectArtifact>
<outputDirectory>lib</outputDirectory>
<unpack>false</unpack>
</dependencySet>
</dependencySets>
<fileSets>
<!-- 把项目相关的说明文件，打包进zip文件的根目录 -->
<fileSet>
<directory>${project.basedir}</directory>
<outputDirectory>/</outputDirectory>
<includes>
<include>README*</include>
<include>LICENSE*</include>
<include>NOTICE*</include>
</includes>
</fileSet>
<!-- 把项目的配置文件，打包进zip文件的config目录 -->
<fileSet>
<directory>${project.basedir}\conf</directory>
<outputDirectory>conf</outputDirectory>
<includes>
<include>*.xml</include>
<include>*.properties</include>
<include>*.key</include>
</includes>
</fileSet>
<!-- 把项目的脚本文件目录（ src/main/scripts ）中的启动脚本文件，打包进zip文件的跟目录 -->
<fileSet>
<directory>${project.build.scriptSourceDirectory}</directory>
<outputDirectory></outputDirectory>
<includes>
<include>startup.*</include>
</includes>
</fileSet>
<!-- 把项目自己编译出来的jar文件，打包进zip文件的根目录 -->
<fileSet>
<directory>${project.build.directory}</directory>
<outputDirectory></outputDirectory>
<includes>
<include>*.jar</include>
</includes>
</fileSet>
</fileSets>
</assembly>
(2)
pom.xml:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.1</version>
<configuration>
<compilerVersion>1.6</compilerVersion>
<source>1.6</source>
<target>1.6</target>
</configuration>
</plugin>
<!-- The configuration of maven-jar-plugin -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>2.4</version>
<!-- The configuration of the plugin -->
<configuration>
<!-- Configuration of the archiver -->
<archive>
<!-- do not include pom.xml and pom.properties in the jar package -->
<addMavenDescriptor>false</addMavenDescriptor>
<!-- Manifest specific configuration -->
<manifest>
<!-- put third party jar package into the classpath of manifest -->
<addClasspath>true</addClasspath>
<!-- the prefix of the jar items in the classpath, it depends on the location(folder) of jar files -->
<classpathPrefix>lib/</classpathPrefix>
<!-- main class of the jar package-->
<mainClass>com.tang.your-Main-class</mainClass>
</manifest>
</archive>
<!-- excludes some files -->
<excludes>
<exclude>${project.basedir}/xml/*</exclude>
</excludes>
</configuration>
</plugin>
<!-- The configuration of maven-assembly-plugin -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.4</version>
<!-- The configuration of the plugin -->
<configuration>
<!-- Specifies the configuration file of the assembly plugin -->
<descriptors>
<descriptor>conf/package.xml</descriptor>
</descriptors>
</configuration>
<executions>
<execution>
<id>make-assembly</id>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
mvn install后，此时会在target目录下生成一个zip文件，如：
youArtifactId-0.0.1-bin.zip 解压后有：
conf 文件夹， lib文件夹， youArtifactId-0.0.1-bin.jar
