Maven Central充當(dāng)中央存儲(chǔ)庫(kù)管理器，其中二進(jìn)制工件由不同的團(tuán)隊(duì)/公司/個(gè)人上載并與世界其他地方共享。 就像github和其他對(duì)源代碼控制非常有效的源代碼存儲(chǔ)庫(kù)一樣，這些存儲(chǔ)庫(kù)管理器還充當(dāng)您自己生成的二進(jìn)制工件的部署目標(biāo)。

設(shè)置本地存儲(chǔ)庫(kù)管理器具有多個(gè)優(yōu)點(diǎn)。 最主要的是，它們充當(dāng)Maven Central之間的高度可配置代理，因此每個(gè)人都不必從中央存儲(chǔ)庫(kù)下載所有依賴項(xiàng)。 另一個(gè)主要原因是要控制團(tuán)隊(duì)內(nèi)部臨時(shí)生成的工件。 使用存儲(chǔ)庫(kù)管理器的原因詳細(xì)說(shuō)明了完整的好處。

本技術(shù)提示將展示如何設(shè)置本地Nexus信息庫(kù)管理器，以及將工件（快照和發(fā)行版）推送到其中。

讓我們開始吧！

安裝和配置本地Nexus存儲(chǔ)庫(kù)

下載并解壓縮最新的Nexus OSS 。 默認(rèn)管理員的登錄名/密碼是admin / admin123。 默認(rèn)的部署登錄名/密碼是Deployment / deployment123。

以以下方式啟動(dòng)Nexus： nexus-2.11.2-03> ./bin/nexus start Starting Nexus OSS... Started Nexus OSS.

日志可以看成是：

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

或者，您可以從控制臺(tái)本身中顯示日志的位置開始：

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]

將Maven設(shè)置文件（?.m2 / settings.xml）配置為包括以下默認(rèn)部署用戶名和密碼： <?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>

將快照部署到本地Nexus存儲(chǔ)庫(kù)

從github.com/javaee-samples/javaee7-simple-sample簽出一個(gè)簡(jiǎn)單的Java EE示例。

注意，該命令以錯(cuò)誤結(jié)尾。 這類似于此處報(bào)告的內(nèi)容，但奇怪的是文件仍在Nexus上載。 這是來(lái)自localhost：8081 / nexus /＃view-repositories; releases?browsestorage的快照，同時(shí)嘗試測(cè)試多個(gè)版本并想知道這些“虛假”錯(cuò)誤消息：

該錯(cuò)誤將需要更多的調(diào)試，但現(xiàn)在至少可以將快照和發(fā)行版本存儲(chǔ)在本地Nexus存儲(chǔ)庫(kù)中。

更新： Manfred Moser通過(guò)發(fā)送拉取請(qǐng)求幫助調(diào)試了該錯(cuò)誤。 現(xiàn)在，此錯(cuò)誤已消失，而應(yīng)顯示類似以下內(nèi)容：

您學(xué)習(xí)了如何設(shè)置本地Nexus Repository并向其推送快照和發(fā)布版本。 隨后的博客將展示如何將此存儲(chǔ)庫(kù)用于CI / CD。

請(qǐng)享用！
