simple-command项目被配置成创建一个单独的包含项目本身字节码以及所有依赖字节码的JAR文件。要创建这个装配制品，从simple-command项目目录运行Maven
Assembly插件的assembly目标：
$ mvn assembly:assembly

构建过程经过了生命周期中编译字节码，运行测试，然后最终为该项目构建一个JAR。然后assembly:assembly目标创建一个带有依赖的JAR，它将所有依赖解压到一个临时目录，然后将所有字节码收集到target/目录下一个名为simple-command-jar-with-dependencies.jar的JAR中。这个“超级的”JAR的体重为15MB。
在你运行这个命令行工具之前，你需要调用Hibernate3插件的hbm2ddl目标来创建HSQLDB数据库。在simple-command目录运行如下的命令：
$ mvn hibernate3:hbm2ddl
[INFO] Scanning for projects...
[INFO] Searching repository for plugin with prefix: 'hibernate3'.
[INFO] org.codehaus.mojo: checking for updates from central

[INFO] ------------------------------------------------------------------------
在此之后，你应该能在simple-command下看到data/目录。该data/目录包含了HSQLDB数据库。要运行这个命令行天气预报器，在simple-command/项目目录下运行如下命令：
$ java -cp target/simple-command-jar-with-dependencies.jar \
org.sonatype.mavenbook.weather.Main 60202
