启动Storm-MQTT-1
根据消息，Strom的新版本增加了许多连接功能，我会立即尝试使用storm-mqtt。
“Storm-MQTT是什么？”
就是这个。试着先跑一下这个例子，不是吗？
计划中的趋势
-
- 从github克隆storm
-
- https://github.com/apache/storm
克隆下来的storm进行构建
按照examples中提供的步骤进行执行
我打算暂时写到第二个，剩下的等下个时机再说。
暴风雨无法建立。
当访问Apache/Storm时，README部分如下显示…
我明白了。或许必须分别构建才行。因此，暂时只针对目标外部库/storm-mqtt进行构建。
风暴mqtt的构建无法通过。
我将尽快进入克隆下载的Storm构建阶段。
所以，按照这个情况来看，storm-mqtt的构建没有通过。嗯，因为有各种依赖关系，所以当然会这样。让我们逐个构建和解决相关部分的问题。

整个团队都不能通过这个构建。
我明白了，那就先从头开始构建storm-core吧，说不定会顺利通过呢。

暴风雨HDFS似乎有问题。
你想试着单独构建storm-hdfs吗？
$mvn install package -Dmaven.test.skip=true

哦…
顺便提一句，我认为编译目标中不包括storm-hdfs会比较麻烦，但是同样的错误也出现在storm-hive。看起来如果不解决这个问题，编译是无法通过的。
结论：需要 test-jar。
因为在storm-core中可能只需要生成一个test-jar，所以按照这个想法进行实施。
mvn test jar:test-jar install
过后，头部的建筑也顺利通过了。
我立刻陷入了麻烦，但终于成功构建完成。现在我打算从这里开始运行我设定的目标，即storm-mqtt的示例。
有人一开始就从头到尾顺利完成建筑吗？
