Настройка локального репозитория Nexus и развертывание файла WAR из Maven

Maven Central служит центральным менеджером репозитория, где двоичные артефакты загружаются различными командами / компаниями / частными лицами и передаются остальному миру. Подобно github и другим репозиториям исходного кода, которые очень эффективны для управления исходным кодом, эти менеджеры репозитория также действуют как назначение развертывания для ваших собственных сгенерированных двоичных артефактов.

Настройка менеджера локального хранилища имеет несколько преимуществ. Основными из них являются то, что они действуют как настраиваемый прокси-сервер между центральным Maven, так что не всем нужно загружать все зависимости из центрального репо. Другой основной причиной является контроль ваших временных сгенерированных артефактов в вашей команде. Причины использования Repository Manager предоставляют подробное объяснение полного набора преимуществ.

Этот технический совет покажет, как настроить локальный менеджер репозитория Nexus и передать в него артефакты — как моментальные снимки, так и выпуски.

Давайте начнем!

Установите и настройте локальный репозиторий Nexus

1. Загрузите и распакуйте последнюю версию Nexus OSS . Логин / пароль администратора по умолчанию — admin / admin123. Логин / пароль для развертывания по умолчанию — развертывание / развертывание123
2. Запустите Nexus как:

   1 2 3

   nexus-2.11.2-03> ./bin/nexus start Starting Nexus OSS... Started Nexus OSS.

   Журналы могут тогда быть замечены как:

   1	nexus-2.11.2-03> tail -f logs/wrapper.log

   Или вы можете начать, где журналы отображаются в самой консоли:

   01 02 03 04 05 06 07 08 09 10 11 12 13 14

   nexus-2.11.2-03> ./bin/nexus console Running Nexus OSS... wrapper  | --> Wrapper Started as Console wrapper  | Launching a JVM... jvm 1    | Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=192m; support was removed in 8.0 jvm 1    | Wrapper (Version 3.2.3) http://wrapper.tanukisoftware.org jvm 1    |   Copyright 1999-2006 Tanuki Software, Inc.  All Rights Reserved. jvm 1    |   . . .   jvm 1    | 2015-02-24 00:17:28,706-0800 INFO  [jetty-main-1] *SYSTEM org.sonatype.nexus.bootstrap.jetty.JettyServer - Running jvm 1    | 2015-02-24 00:17:28,706-0800 INFO  [WrapperListener_start_runner] *SYSTEM org.sonatype.nexus.bootstrap.jetty.JettyServer - Started jvm 1    | 2015-02-24 00:17:30,713-0800 INFO  [ar-4-thread-3] *SYSTEM org.sonatype.nexus.proxy.maven.routing.internal.ManagerImpl - Updated and published prefix file of "Public Repositories" [id=public]

3. Сконфигурируйте файл настроек Maven (~ .m2 / settings.xml), чтобы включить имя пользователя и пароль для развертывания по умолчанию:

   01 02 03 04 05 06 07 08 09 10

   <?xml version="1.0" encoding="UTF-8" standalone="no"?> <settings xmlns="http://maven.apache.org/SETTINGS/1.1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.1.0 http://maven.apache.org/xsd/settings-1.1.0.xsd">    <servers>       <server>         <id>deployment</id>         <username>deployment</username>         <password>deployment123</password>      </server>   </servers> </settings>

Развернуть снимок в локальный репозиторий Nexus

1. Ознакомьтесь с простым примером Java EE по адресу github.com/javaee-samples/javaee7-simple-sample .
2. Создайте и разверните файл WAR в локальном репозитории Nexus как:

   01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95

   Репозиторий моментальных снимков, после отправки нескольких сборок, можно увидеть по адресу localhost: 8081 / nexus / # view-repositories; snapshots ~ browsestorage и выглядит следующим образом:

   

   Фактическое хранилище находится в ../sonatype-work/nexus . Это создается параллельно с тем местом, где когда-либо был распакован комплект Nexus OSS.

   Обратите внимание, как эта команда заканчивается ошибкой. Это похоже на сообщение здесь, но странно то, что файлы все еще загружаются на Nexus. Вот снимок с localhost: 8081 / nexus / # view-repositories; выпускает ~ browsestorage при попытке протестировать несколько выпусков и удивляться этим «ложным» сообщениям об ошибках:

   

   Эта ошибка потребует дополнительной отладки, но по крайней мере снимки и сборки выпуска теперь могут храниться в локальном репозитории Nexus.

ОБНОВЛЕНИЕ: Манфред Мозер помог отладить эту ошибку, отправив запросы на извлечение . Эта ошибка теперь исчезла и вместо этого должна показать что-то вроде:

Вы узнали, как настроить локальный репозиторий Nexus, передать снимок и выпустить сборки для него. Последующие блоги покажут, как этот репозиторий можно использовать для CI / CD.

Наслаждайтесь!
