java - 运行 javac 时找不到包

问题描述

我知道这个问题已经被问过一千次了，但我仍然无法完全理解问题的重点，尤其是在我的情况下。所以，我有一个依赖 TestNG 和 Selenium Java 库的简单项目，并且我在全局安装了这些库，所以我的项目只是从“全局”范围导入它们。

所以要解决这个问题，我应该将该全局文件夹添加到我的类路径中吗？或者这从一开始就不正确，我不应该在项目中全局使用库？

解决方案

我终于明白应该怎么做。因此，要编译类然后运行 ​​TestNG 测试，我这样做了：

javac -cp C:\Users\Yaroslav\IdeaProjects\GoogleSearchTest\lib\* GoogleSearchTest.java

java -cp C:\Users\Yaroslav\IdeaProjects\GoogleSearchTest\src\main\java\;C:\Users\Yaroslav\IdeaProjects\GoogleSearchTest\lib\* org.testng.TestNG testng.xml

更详细地说，在编译类的第一行应该有以下命令模板：

javac -cp "full path to libs folder, where project libraries located" "name of class to compile"

对于运行 TestNG 测试的第二行，模板为：

java -cp "full path to folder where testng.xml file located";"full path to libs folder, where project libraries located" "testNG filename with extension"

如您所见，这非常令人厌烦。我应该学习正确的方法来运行类似的测试而不会头痛......

PS 毕竟我刚学 Maven，现在不需要这些命令了）
