1、生成runnable jar，但是最后并不是一个可执行的jar 而是一个目录
主要使用 三个插件 将所需要的资源拷贝到 /target/Crunchify目录下，注意并没有生成一个jar中去
maven-resources-plugin, maven-dependency-plugin & maven-jar-plugin to generate your complete executable Jar Project? As a result it creates / copies all required files to /target/Crunchify folder.
几点说明：
CrunchifyMavenBuildPlugins is a Maven Project. If you have Java project and wanted to convert it into Maven project then follow this tutorial.src and resources.resources folder we do have a folder called Scripts which contains one executableshell script file.CrunchifyMain.java is a main starting point which has main(String args[]) method inside.pom.xml file in which we will add Maven Plugins which will build executable .jar project with all included dependanciespom文件如下：注意build标签下的3个plugins<build>
1 <pluginManagement> 2 <plugins> 3 <plugin> 4 <groupId>org.apache.maven.plugins</groupId> 5 <artifactId>maven-compiler-plugin</artifactId> 6 <version>2.3.1</version> 7 <configuration> 8 <source>1.7</source> 9 <target>1.7</target> 10 </configuration> 11 </plugin> 12 </plugins> 13 </pluginManagement> 14 <plugins>
<!--说明：The Resources Plugin 会将project resources拷贝到输出目录.project resources are the resources associated to the main source code-->
<plugin>

最后看看结果
2、生成到一个jar包中，这个时候需要在插件maven-shade-plugin上做文章，主要用到的技术是 Resource Transformers
主要看下pom文件
