Maven私服Nexus的搭建和使用(Mac)

1.下載對應的安裝包

https://www.sonatype.com/oss-thank-you-mac-tgz

注意：目前的版本有2.X 和 3.X ，2.X的支持對Maven更友好一點，3.X的支持範圍更廣，支持ruby和docker。如果單純的maven私服，建議使用2.x

2.解壓安裝包，並進入對應的bin目錄下啓動nexus

./nexus start

注意：3.X要求JDK的版本在1.8以上

3.訪問地址，3.x默認是127.0.0.1:8081 2.x默認是127.0.0.1:8081/nexus ,默認的登陸賬戶密碼爲admin/admin123

修改端口或者密碼，在etc下的nexus-default.properties

4.簡單介紹一下Repository

Repository的type屬性有：proxy，hosted，group三種。

proxy：即你可以設置代理，設置了代理之後，在你的nexus中找不到的依賴就會去配置的代理的地址中找

hosted：你可以上傳你自己的項目到這裏面

group：它可以包含前面兩個，是一個聚合體。一般用來給客戶一個訪問nexus的統一地址。

簡單的說，就是你可以上傳私有的項目到hosted，以及配置proxy以獲取第三方的依賴（比如可以配置中央倉庫的地址）。前面兩個都弄好了之後，在通過group聚合給客戶提供統一的訪問地址

5.如何上傳jar包

先設置settings.xml,這裏主要是配置用戶名和密碼，注意這裏的id要和respositoryId對應

<servers>
<server>
<id>nexus</id>
<username>admin</username>
<password>admin123</password>
</server>
</servers>

控制檯

mvn deploy:deploy-file -DgroupId=ebay -DartifactId=ebay -Dversion=0.0.1-SNAPSHOT -Dpackaging=jar -Dfile=/Users/yuliangliang/ebay-0.0.1-SNAPSHOT.jar -Durl=http://localhost:8081/repository/maven-snapshots/ -DrepositoryId=nexus

效果如下

也可以同步本地倉庫到私服上去

6.項目中的使用，這樣就能在項目中引用了，具體的引用可以在pom中配置，也可以在maven的settings.xml文件中修改

<mirrors>
<mirror>
<id>nexus</id>
<mirrorOf>*</mirrorOf>
<url>http://127.0.0.1:8082/nexus/content/groups/public/</url>
</mirror>
</mirrors>
<profiles>
<profile>
<id>nexus</id>
<repositories>
<repository>
<id>nexus</id>
<url>http://127.0.0.1:8082/nexus/content/groups/public/</url>
<releases><enabled>true</enabled></releases>
<snapshots><enabled>true</enabled></snapshots>
</repository>
</repositories>
<pluginRepositories>
<pluginRepository>
<id>nexus</id>
<url>http://127.0.0.1:8082/nexus/content/groups/public/</url>
<releases><enabled>true</enabled></releases>
<snapshots><enabled>true</enabled></snapshots>
</pluginRepository>
</pluginRepositories>
</profile>
</profiles>
<activeProfiles>
<activeProfile>nexus</activeProfile>
</activeProfiles>

7.上傳項目到私服上去

先設置settings.xml,配置servers，見步驟5

項目的pom文件添加如下代碼

<distributionManagement>
<repository>
<id>release</id>
<name>Release Repository</name>
<url>http://ip/nexus/content/repositories/releases</url>
</repository>
<snapshotRepository>
<id>snapshot</id>
<name>Snapshot Repository</name>
<url>http://ip/nexus/content/repositories/snapshots</url>
</snapshotRepository>
</distributionManagement>
