我继承了一个代码库:)
在 src/test/java/ 下有一个我需要运行的文件(我需要运行它public static void main(String[] args)
,而不是其中的@Test
方法)。
我得到的最接近的是:
mvn -e exec:java -Dexec.mainClass="com.me.packagex.RunFile" -Dexec.classpathScope="test"
但随后失败了,这似乎是因为 RunFile 想要使用 src/main/java/com/me/packagex/ 下存在的类(注意,/main/,而不是 /test/)。那里的文件与RunFile在同一个包中,即'package com.me.packagex;'。
如果我删除它,-Dexec.classpathScope="test"
那么它根本找不到 RunFile。好像我需要给它两个范围,但它不接受“测试,编译”。
我从(已去世)那里继承了这个的人曾经从 Eclipse 运行它。我需要一种从命令行运行它的方法。
我希望这能得到清楚的解释。
特维姆,
这是有希望的。帕斯卡,我试过你的例子,但这对我不起作用。
虽然现在我看它 - 它没有找到 Demo,而不是没有找到 Dog。
