方法一. mvn assembly 或 mvn package (一個jar包)

1. <build>
2.       <plugins>
3.           <plugin>
4.               <artifactId>maven-assembly-plugin</artifactId>
5.               <
   configuration>
6.                   <archive>
7.                       <manifest>
8.                           <mainClass>com.tang.CSVUtils</mainClass>
9.                       </manifest>
10.                   </archive>
11.                   <descriptorRefs>
12.                       <
    descriptorRef>
13.                           jar-with-dependencies  
14.                       </descriptorRef>
15.                   </descriptorRefs>
16.               </configuration>
17.               <!-- 加上下面這一段,使用 mvn package命令,不加則使用mvn assembly-->
18.               <!-- <executions
    >
19.                   <execution>
20.                       <id>make-assemble</id>
21.                       <phase>package</phase>
22.                       <goals>
23.                           <goal>single</goal>
24.                       </goals>
25.                   </execution>
26.               </executions> -->
27.           </plugin>
28.       </plugins>
29.   </build>

Target目錄生成如下檔案：

其中，

testLog4j-0.1.jar 是不可直接執行的，因為沒有帶第三方包。

testLog4j-0.1-jar-with-dependencies.jar 就是帶有第三方包的可執行 jar 包，

在命令列執行 java -jar testLog4j-0.1-jar-with-dependencies.jar 即可執行

方法二：mvn package(一個jar包和一個lib資料夾)

1. <build>
2.     <plugins>
3.         <plugin>
4.             <groupId>org.apache.maven.plugins</groupId>
5.             <artifactId>maven-jar-plugin</artifactId>
6.             <version>2.4</version>
7.             <configuration>
8.                 <archive>
9.                     <manifest>
10.                         <addClasspath>true</addClasspath>
11.                         <classpathPrefix>lib/</classpathPrefix>
12.                         <mainClass>com.tang.CSVUtils</mainClass>
13.                     </manifest>
14.                 </archive>
15.             </configuration>
16.         </plugin>
17.         <plugin>
18.             <groupId>org.apache.maven.plugins</groupId>
19.             <artifactId>maven-dependency-plugin</artifactId>
20.             <executions>
21.                 <execution>
22.                     <id>copy</id>
23.                     <phase>package</phase>
24.                     <goals>
25.                         <goal>copy-dependencies</goal>
26.                     </goals>
27.                     <configuration>
28.                         <outputDirectory>${project.build.directory}/lib</outputDirectory>
29.                     </configuration>
30.                 </execution>
31.             </executions>
32.         </plugin>
33.     </plugins>
34. </build>

執行maven package 進行打包進入target目錄。

其中lib就是第三方jar包的目錄，在其他專案引入testLog4j-0.1.jar會自動找到並引入lib裡面的包.

只需要拷貝這兩個（lib和testLog4j-0.1.jar）即可放到其他地方用
