有個Maven私服能夠節省網絡帶寬,也方便管理咱們的jar包和發佈構建到遠程倉庫,本文就介紹瞭如何在linux下一步步使用nexus搭建maven私服。java
官網最新Nexus下載地址: https://www.sonatype.com/download-oss-sonatypelinux
解壓後會在同級目錄中,出現兩個文件夾: nexus-oss-webapp-1.8.0
和 sonatype-work
,前者包含了nexus的運行環境和應用程序,後者包含了你本身的配置和數據。web
$ mkdir nexus $ tar xzvf /home/jili/nexus-2.7.0-05-bundle.tar.gz $ ls nexus-2.7.0-05 sonatype-work
$ cd bin/ $ ls jsw nexus nexus.bat $ ./nexus Usage: ./nexus { console | start | stop | restart | status | dump } $ ./nexus start Starting Nexus OSS... Started Nexus OSS.
查看控制檯:apache
$ ./nexus console
顯示未啓動成功,報錯以下:bootstrap

緣由:查找緣由是JDK版本太低形成的,升級到最新的JDK7或者使用nexus-2.4-bundle.tar.gz版本JDK6會支持.windows
Nexus全部版本下載地址: http://www.sonatype.org/nexus/archived網絡
下載Nexus2.4重來app
$ ls nexus-2.4.0-09 sonatype-work $ cd nexus-2.4.0-09/bin/ $ ls jsw nexus nexus.bat $ ./nexus Usage: ./nexus { console | start | stop | restart | status | dump } $ ./nexus start Starting Nexus OSS... Started Nexus OSS. $ ./nexus console Running Nexus OSS... Nexus OSS is already running.
控制檯顯示啓動成功。less
查看nexus日誌:eclipse
$ cd nexus-2.4.0-09/logs $ ls wrapper.log $ tail -f wrapper.log
訪問網址: http://yourhostname:8081/nexus
右上角以admin登錄,默認用戶名/密碼:admin/admin123。
3rd party、Snapshots、Releases這三個,分別用來保存第三方jar、項目組內部的快照、項目組內部的發佈版.
將第三方的jar上傳到nexus上面:
點擊Upload Artifact(s)按鈕提交後即上傳。
查看上傳的jar包以下:
在項目中使用私服的jar包配置pom.xml以下:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.vclk.mkt.crawler</groupId> <artifactId>MarketingCrawler</artifactId> <packaging>jar</packaging> <version>0.3</version> <name>MarketingCrawler</name> <url>http://maven.apache.org</url> <!-- 倉庫地址 --> <repositories> <repository> <id>nexus</id> <name>Team Nexus Repository</name> <url>http://yourhostname:8081/nexus/content/groups/public</url> </repository> </repositories> <!-- 插件地址 --> <pluginRepositories> <pluginRepository> <id>nexus</id> <name>Team Nexus Repository</name> <url>http://yourhostname:8081/nexus/content/groups/public</url> </pluginRepository> </pluginRepositories> <!-- jar --> <dependencies> <dependency> <groupId>de.innosystec</groupId> <artifactId>java-unrar</artifactId> <version>0.5</version> </dependency> </dependencies> </project>
Maven在項目根目錄下執行mvn eclipse:eclipse命令時,所依賴的jar包都會從私服中下載到本地並關聯上項目,私服中沒有就會從網絡上下載到私服,本地再從私服下載。
在工程的pom.xml中添加:
<distributionManagement> <repository> <id>nexus-releases</id> <url>http://yourhostname:8081/nexus/content/repositories/releases/</url> </repository> <snapshotRepository> <id>nexus-snapshots</id> <url>http://yourhostname:8081/nexus/content/repositories/snapshots/</url> </snapshotRepository> </distributionManagement>
進入maven的安裝目錄apache-maven-3.1.1\conf目錄下,向settings.xml配置文件中的 語句塊中添加以下所示:
<servers> <server> <id>nexus-releases</id> <username>admin</username> <password>admin123</password> </server> <server> <id>nexus-snapshots</id> <username>admin</username> <password>admin123</password> </server> </servers>
進入windows命令行,在工程所在目錄下執行
mvn deploy
所部署的包就自動上傳到了nexus安裝目錄下的 /maven/nexus/sonatype-work/nexus/storage/releases/com/vclk/mkt/crawler/MarketingCrawler/0.3
目錄
項目中的各類jar包和項目快照等都放在 /nexus/sonatype-work/nexus/storage/
目錄下,在這個目錄下包括如下各類目錄和存放相應文件。
/nexus/sonatype-work/nexus/storage/central
- 用於放置maven從中央倉庫中下載下來的項目pom.xml中配置到的相關jar包;
/nexus/sonatype-work/nexus/storage/thirdparty
- 用於放置本身手動上傳的第三方jar包;
/nexus/sonatype-work/nexus/storage/releases
- 用於放置項目deploy後的發佈版。
