Git в IDEA (Alt+9)


GitHub1. Зарегистрироваться2. Создать репозиторий3. Пушнуть код

Запушили


В IDEAAlt+9 — status, diff, log

Ctrl+D — diff

Ctrl+K — commit

Shift+Ctrl+K — push


Последовательность1. Пишем код2. Проверяем изменения (и гоняем тесты)

git statusgit diff

3. Фиксируем измененияgit addgit commit

4. Публикуем измененияgit push


Домашнее задание1. Создать репозиторий на GitHub.

2. Запушить проект.

3. Прислать ссылку на проект.

4. Весь код в этом и дальнейших занятиях публиковать на GitHub.
