maven-jar-plugin用于生成META-INF/MANIFEST.MF文件的部分内容
com.xxg.Main
指定MANIFEST.MF中的Main-Class

| <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>
<mainClass>com.xxx.xxx.Main</mainClass>
</manifest>

</configuration>
<executions>
<execution>
<id>make-assembly</id>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
</execution>
</executions>
</plugin>
|
这里没有指定
1
| <descriptor>src/main/assembly/assembly.xml</descriptor>
|
而是用的
1
2
3
| <descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
|
这个jar-with-dependencies是assembly预先写好的一个，组装描述引用（assembly descriptor）
默认的compile scope范围是会打进jar包的，而且依赖也全部会打进去，所有有些包打完之后有可能会很大，可将scope范围改成provided，就不会打进去了。
指定打包输出的文件名

| <configuration>
<finalName>CSV转Excel工具</finalName>
<appendAssemblyId>false</appendAssemblyId>
......
|
常规做法
一般项目都比较大，不会打成一个jar包，一般都是打成一个tar包，里面包含启动脚本，配置文件等
使用assembly插件
一般目录结构如下：
1
2
3
4
5
6
7
8
9
10
11
12
13
14
| │
└─assembly
│ assembly.xml
│
├─bin
│ dump.sh
│ restart.sh
│ server.sh
│ start.sh
│ stop.sh
│
└─conf
log4j.properties
system.properties
|
