maven打包方式

shade方式：

<build>
		<plugins>
			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-shade-plugin</artifactId>
				<version>1.2.1</version>
				<executions>
					<execution>
						<phase>package</phase>
						<goals>
							<goal>shade</goal>
						</goals>
						<configuration>
							<transformers>
								<transformer
									implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
									<mainClass>com.vs.mingli.HelloWorld</mainClass>
								</transformer>
							</transformers>
						</configuration>
					</execution>
				</executions>
			</plugin>
		</plugins>
	</build>

Maven有好几个插件能帮助用户完成上述任务，不过用起来最方便的还是maven-shade-plugin，它可以让用户配置Main-Class的值，然后在打包的时候将值填入/META-INF/MANIFEST.MF文件。关于项目的依赖，它很聪明地将依赖JAR文件全部解压后，再将得到的.class文件连同当前项目的.class文件一起合并到最终的CLI包中，这样，在执行CLI JAR文件的时候，所有需要的类就都在Classpath中了。

assemble，英文意思是：聚合，可以打成任务形式的包，但是需要配置的东西也就比较复杂的。

<build>
		<plugins>
			<plugin>
				<artifactId>maven-assembly-plugin</artifactId>
				<version>2.4</version>
				<executions>
					<execution>
						<id>make-assembly</id>
						<phase>package</phase>
						<goals>
							<goal>single</goal>
						</goals>
						<configuration>
							<skipAssembly>false</skipAssembly><!-- 跳过这个执行器 -->
							<archive>
								<manifest>
									<mainClass>net.hxtek.scheduler.Main</mainClass>
								</manifest>
							</archive>
							<descriptors>
								<descriptor>
									src/main/assemble/package.xml
								</descriptor>
							</descriptors>
						</configuration>
					</execution>
				</executions>
			</plugin>
		</plugins>
	</build>

src/main/assemble/package.xml

用来详细配置包的结构

<assembly

	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

			<useProjectArtifact>true</useProjectArtifact>
			<outputDirectory>/</outputDirectory><!-- 将scope为runtime的依赖包打包到lib目录下。 -->
			<scope>runtime</scope>
		</dependencySet>
	</dependencySets>
    <fileSets>
        <fileSet>
            <directory>${project.build.outputDirectory}</directory>
