maven 自动生成运行脚本插件appassembler-maven-plugin

appassembler-maven-plugin可以自动生成跨平台的启动脚本，省去了手工写脚本的麻烦，而且还可以生成jsw的后台运行程序。

appassembler的配置比较简单，在pom.xml的配置文件加入插件配置。

比如说不同的启动脚本，可以如下配置

<plugin>
				<groupId>org.codehaus.mojo</groupId>
				<artifactId>appassembler-maven-plugin</artifactId>
				<version>1.2.1</version>
				<configuration>
					<configurationDirectory>conf</configurationDirectory>
					<configurationSourceDirectory>src/main/resources</configurationSourceDirectory>
					<copyConfigurationDirectory>true</copyConfigurationDirectory>
					<includeConfigurationDirectoryInClasspath>true</includeConfigurationDirectoryInClasspath>
					<assembleDirectory>${project.build.directory}/chj-search-client</assembleDirectory>
					<extraJvmArguments>-Xms128m</extraJvmArguments>
					<binFileExtensions>
						<unix>.sh</unix>
					</binFileExtensions>
					<platforms>
						<platform>windows</platform>
						<platform>unix</platform>
					</platforms>
					<repositoryName>lib</repositoryName>
					<programs>
						<program>
							<mainClass>com.chj360.search.client.App</mainClass>
						</program>
					</programs>
				</configuration>
			</plugin>

然后运行maven命令 :mvn package appassembler:assemble

就可以自动生成整个的依赖文件，配置文件和运行脚本了。

一些配置说明 

configurationDirectory：生成配置文件路径

configurationSourceDirectory：配置文件原路径，默认为src/main/config

assembleDirectory:整体包目录

extraJvmArguments：jvm参数

binFileExtensions：生成脚本的后缀

platforms：生成哪几种平台

repositoryName：依赖包目录，默认repo

programs：这个必须参数，启动的主class

生成jsw也是一个简单的配置
