标签说明

• finalName：指定生成文件名称，默认为artifactId-version
• appendAssemblyId：生成文件时，是否追加assemblyId到文件名上，这里的assemblyId即jar-with-dependencies；若选择true，生成文件名为pozhenzi-jar-with-dependencies.jar；
• descritorRef：assembly描述符的引用，assembly内置的描述符有bin、jar-with-dependencies、src、project这几种；
• mainClass：指定main方法入口，指定后在MANIFEST.MF会生成Main-Class属性，这样便可以通过java -jar mainClass的方式运行jar了；
