Ranger 这个项目比较老了，更新不算多，所以编译方式也没有更新到比较新的方式，编译报错了有时候还是不太容易找到问题的，但是一定要记得，Maven 的日志是非常有用的，对于 Debug 来说有很大的帮助，所以一定要仔细看日志的报错内容，从图上看，最终抛出的问题是 An Ant BuildException has occured: exec returned: 1 ，这个我之前也没见过，但是很自然，我就加了 mvn package -X 来打印编译过程的 Debug 级别日志了。最后如下所示，around Ant part ...<exec failonerror="true" executable="python">... @ 4:48 就是这句，给了我灵感，因为我在 Mac 本地编译的，按照经验，我想到的是编译文件里指定用 python，会不会是版本不对导致无法执行，比如 python2 和 python3 的区别。于是我找到了这个变量控制的地方，如下图。
