在項(xiàng)目中使用

配置認(rèn)證信息

在Maven settings.xml中添加Nexus認(rèn)證信息(servers節(jié)點(diǎn)下)

<server>
    <id>nexus-releases</id>
    <username>admin</username>
    <password>15955655592</password>
</server>

<server>
    <id>nexus-snapshots</id>
    <username>admin</username>
    <password>15955655592</password>
</server>

在pom.xml中添加

<distributionManagement>
        <repository>
            <id>nexus-releases</id>
            <name>Nexus Release Repository</name>
            <url>http://192.168.197.138:8081/repository/maven-releases/</url>
        </repository>
        <snapshotRepository>
            <id>nexus-snapshots</id>
            <name>Nexus Snapshots Repository</name>
            <url>http://192.168.197.138:8081/repository/maven-snapshots/</url>
        </snapshotRepository>
    </distributionManagement>

• 注意：ID名稱(chēng)必須要與settings.xml中servers配置的ID名稱(chēng)保持一致
• 項(xiàng)目版本號(hào)中有SNAPSHOT表示的,會(huì)發(fā)布到Nexus Snapshots Repository,否則發(fā)布到Nexus Releases Repository,并根據(jù)ID去匹配授權(quán)賬號(hào)

IDEA中運(yùn)行maven指令

$ mvn deploy


上傳第三方 JAR 包

# 如第三方JAR包：aliyun-sdk-oss-2.2.3.jar
mvn deploy:deploy-file 
  -DgroupId=com.aliyun.oss 
  -DartifactId=aliyun-sdk-oss 
  -Dversion=2.2.3 
  -Dpackaging=jar 
  -Dfile=D:\aliyun-sdk-oss-2.2.3.jar 
  -Durl=http://127.0.0.1:8081/repository/maven-3rd/ 
  -DrepositoryId=nexus-releases

注意事項(xiàng)：

• 建議在上傳第三方 JAR 包時(shí)趁窃，創(chuàng)建單獨(dú)的第三方 JAR 包管理倉(cāng)庫(kù)，便于管理有維護(hù)。（maven-3rd）
• -DrepositoryId=nexus-releases 對(duì)應(yīng)的是 settings.xml 中 Servers 配置的 ID 名稱(chēng)。（授權(quán)）
