|
Important
|
The main package for these solutions should be com.epam.prd.jjop.helpers.
|
|
Tip
|
You can add new dependencies and plugins to the pom.xml if necessary.
|
-
Studying about helpers on your and the other’s code.
-
Creating a source of the knowledge on the subject that you can come back to.
-
Exercising work with shared repository and forks.
-
Fork the repository (button in the upper right corner of the main page).
-
Create an issue with chosen topic in the main repository.
-
Implement your solution to the task given to you during lecture about helpers.
-
Create a commit with a meaningful message.
-
Push the changes to a remote master branch on your fork.
NoteYou don’t have to use a feature branch, only masteris fine. -
Create a Pull Request to merge it to
EPAM-Online-Courses/helpers-3rd-ed:master. -
Review code of the others.
YOU WILL NOW BE WORKING ON THE FORKED REPO, NOT ON THIS ONE, BUT ON YOUR GITHUB COPY OF IT, CALLED THE FORK. WE REPEAT, YOU WILL NOW BE WORKING ON THE FORK. Commands and task steps to do ON THE FORK. It's to be done ON THE FORK, ok? NOT HERE, NOT IN YOUR LOCAL REPOSITORY.
-
Your implementation shall not break any of the existing solutions.
-
Your colleagues have to review your code and you should apply theirs remarks.
-
PRs will be accepted ASAP once they are reviewed and we see they’re demonstrating API assigned to you during the lecture about helpers.
