Как я могу ускорить процесс сборки с помощью Maven

Я использую Maven в качестве инструмента для сборки. В настоящее время я строю с использованием этой команды.

Щелкните правой кнопкой мыши по проекту> Maven clean.

После этого:

Щелкните правой кнопкой мыши по проекту> Maven install

Это занимает 3 минуты для меня. Есть ли способ ускорить мой процесс?

Я уже посмотрел на это. Но я этого не понял. Может кто-нибудь помочь мне?

Ответ 1

Если вы используете несколько модулей maven в проекте, это может сработать для вас: я использую Maven в основном через консоль, поэтому у меня нет опыта с этим в eclipse, но с Maven 3 Maven поддерживает параллельные сборки, Эта функция работает из коробки, но ее успех во многом зависит от используемых вами плагинов, поскольку сторонние плагины могут не разрабатываться таким образом.

Чтобы активировать параллельные сборки, запустите maven с параметром -T:

mvn clean install -T 2

работает с двумя потоками.

mvn clean install -T 2C

работает с 2 потоками на процессор.

Maven определит порядок сборки и максимально распараллелит.

К сожалению, если ваша структура модуля проекта очень линейна, то есть проект A → проект B → проект C, это не принесет вам пользы.

Ответ 2

Если ваш проект имеет тестовые примеры, вы можете пропустить тест, выполнив следующую команду.

mvn clean install -Dmaven.test.skip=true

Ответ 3

просто старайтесь не скачивать каждый раз Выполните Maven в автономном режиме, чтобы избежать загрузки зависимостей при каждом запуске вашей сборки.

Если вы используете командную строку, вы можете использовать -o как аргумент.
