mvn test giving error 'cannot find Symbol'

Question

I have a spring-boot project and I am programming some tests using Junit, in Eclipse I ran the tests without having problems, however, in the terminal, while trying to execute the command mvn test or mvn build an error occurs in my Testutil class that never happened in Eclipse saying 'cannot find Symbol'.

Can’t find the class ?

That is the mistake:

Answer 1

I wanted to run the tests and then generate the. Project jar, the error I made was that instead of executing the mvn package command I ran mvn build and so the error occurred, I confused the commands. Now it’s working!
