Package not found when running javac

I know that this question was already asked thousand times, but I still can't fully understand the point of the problem, especially in my case. So, I have simple project with dependency of TestNG and Selenium Java libraries, and I have these libraries installed globally, so my project just import them from "global" scope.

So to solve the problem I should add that global folder to my classpath ? Or this in not right from the beginning and I should not use libraries globally in projects ?

Solution

I finally understand how it should be done. So, to compile class and then run TestNG test I done this:

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

More detailed, in first line to compile class there should be a following command template:

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

And for second line, which run TestNG test, template is:

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

And this is very tiresome, as you can see. I should learn proper way to run similar tests without headache ...

P.S. After all, I just learn Maven and there is no need for these commands now )
