準(zhǔn)備工作使用前請(qǐng)確保您已安裝JDK及Maven。如果您尚未安裝，可以點(diǎn)擊下面鏈接下載安裝：JDK官網(wǎng)下載地址：
https://www.oracle.com/technetwork/java/javase/downloads/index.htmlMaven加速地址：https://repo.huaweicloud.com/apache/maven/maven-3/
使用說明點(diǎn)擊此處 下載settings.xml文件，覆蓋<Maven安裝目錄>/conf/settings.xml文件即可。如果您不想覆蓋配置文件，可以手動(dòng)在settings.xml文件中的mirrors節(jié)點(diǎn)中添加如下內(nèi)容：
<mirror> <id>huaweicloud</id> <mirrorOf>*</mirrorOf> <url>https://repo.huaweicloud.com/repository/maven/</url></mirror>
相關(guān)網(wǎng)址Maven官方地址：
https://maven.apache.orgMaven搜索地址：http://mvnrepository.com
1.在mirrors節(jié)點(diǎn)中添加如下配置：（可選，使用華為開源鏡像站加速下載開源組件）
<mirror> <id>z_mirrors</id> <mirrorOf>*,!releases,!snapshots</mirrorOf> <url>https://repo.huaweicloud.com/repository/maven/</url> </mirror>
2.在servers節(jié)點(diǎn)中添加如下配置：（password從下載的settings.xml文件中獲?。?/p>
<server> <id>releases</id> <username>088dbeef3980f4050f6fc007779eab60_088dbef03980f2d21f98c007dcbde04f</username> <password>************</password> </server> <server> <id>snapshots</id> <username>088dbeef3980f4050f6fc007779eab60_088dbef03980f2d21f98c007dcbde04f</username> <password>************</password> </server>
3.在profiles節(jié)點(diǎn)中添加如下配置
<profile> <id>MyProfile</id> <repositories> <repository> <id>releases</id> <url>https://devrepo.devcloud.cn-north-4.huaweicloud.com/07/nexus/content/repositories/088dbeef3980f4050f6fc007779eab60_1_0/</url> <releases> <enabled>true</enabled> </releases> <snapshots> <enabled>false</enabled> </snapshots> </repository> <repository> <id>snapshots</id> <url>https://devrepo.devcloud.cn-north-4.huaweicloud.com/07/nexus/content/repositories/088dbeef3980f4050f6fc007779eab60_2_0/</url> <releases> <enabled>false</enabled> </releases> <snapshots> <enabled>true</enabled> </snapshots> </repository> </repositories> </profile>
打開maven的配置文件(windows機(jī)器一般在maven安裝目錄的conf/settings.xml)，在<mirrors></mirrors>標(biāo)簽中添加mirror子節(jié)點(diǎn):
<mirror> <id>aliyunmaven</id> <mirrorOf>*</mirrorOf> <name>阿里云公共倉(cāng)庫(kù)</name> <url>https://maven.aliyun.com/repository/public</url></mirror>
如果想使用其它代理倉(cāng)庫(kù),可在<repositories></repositories>節(jié)點(diǎn)中加入對(duì)應(yīng)的倉(cāng)庫(kù)使用地址。以使用spring代理倉(cāng)為例：
<repository> <id>spring</id> <url>https://maven.aliyun.com/repository/spring</url> <releases> <enabled>true</enabled> </releases> <snapshots> <enabled>true</enabled> </snapshots></repository>
1.在mirrors節(jié)點(diǎn)中添加如下配置：（可選，使用阿里開源鏡像站加速下載開源組件）
<mirror> <id>mirror</id> <mirrorOf>!rdc-releases,!rdc-snapshots</mirrorOf> <url>https://maven.aliyun.com/repository/public</url> </mirror>在settings.xml中添加認(rèn)證信息
在Maven的的默認(rèn)settings.xml中找到servers的部分，添加一個(gè)server配置如下。
<servers> <server> <id>rdc-releases</id> <username>***</username> <password>******</password> </server> <server> <id>rdc-snapshots</id> <username>***</username> <password>******</password> </server></servers>
3.在profiles節(jié)點(diǎn)添加如下配置, 其中 repository 是順序搜索下載包的.
<profile> <id>rdc-private-repo</id> <repositories> <repository> <id>rdc-releases</id> <url>https://repo.rdc.aliyun.com/repository/78947-release-CfzLQ7/</url> <releases> <enabled>true</enabled> </releases> <snapshots> <enabled>false</enabled> </snapshots> </repository> <repository> <id>rdc-snapshots</id> <url>https://repo.rdc.aliyun.com/repository/78947-snapshot-XtuBsZ/</url> <releases> <enabled>false</enabled> </releases> <snapshots> <enabled>true</enabled> </snapshots> </repository> </repositories> <pluginRepositories> <pluginRepository> <id>rdc-releases</id> <url>https://repo.rdc.aliyun.com/repository/78947-release-CfzLQ7/</url> <releases> <enabled>true</enabled> </releases> <snapshots> <enabled>false</enabled> </snapshots> </pluginRepository> <pluginRepository> <id>rdc-snapshots</id> <url>https://repo.rdc.aliyun.com/repository/78947-snapshot-XtuBsZ/</url> <releases> <enabled>false</enabled> </releases> <snapshots> <enabled>true</enabled> </snapshots> </pluginRepository> </pluginRepositories> </profile>制品上傳配置
配置好了settings.xml后，在代碼庫(kù)根目錄下的pom.xml加入以下配置:
<!-- 需要發(fā)布二方包 則打開下列的配置 --><distributionManagement> <repository> <id>rdc-releases</id> <url>https://repo.rdc.aliyun.com/repository/78947-release-CfzLQ7/</url> </repository> <snapshotRepository> <id>rdc-snapshots</id> <url>https://repo.rdc.aliyun.com/repository/78947-snapshot-XtuBsZ/</url> </snapshotRepository></distributionManagement>
然后運(yùn)行以下命令即可將制品推送到私有倉(cāng)庫(kù)中:
$ mvn clean deploy -DskipTests
Maven中-DskipTests和-Dmaven.test.skip=true的區(qū)別在使用mvn package進(jìn)行編譯、打包時(shí)，Maven會(huì)執(zhí)行src/test/java中的JUnit測(cè)試用例，有時(shí)為了跳過測(cè)試，會(huì)使用參數(shù)-DskipTests和-Dmaven.test.skip=true，這兩個(gè)參數(shù)的主要區(qū)別是：
-DskipTests，不執(zhí)行測(cè)試用例，但編譯測(cè)試用例類生成相應(yīng)的class文件至target/test-classes下。-Dmaven.test.skip=true，不執(zhí)行測(cè)試用例，也不編譯測(cè)試用例類。
雖然mirrors可以配置多個(gè)子節(jié)點(diǎn)，但是它只會(huì)使用其中的一個(gè)節(jié)點(diǎn)，即默認(rèn)情況下配置多個(gè)mirror的情況下，只有第一個(gè)生效，只有當(dāng)前一個(gè)mirror無法連接的時(shí)候，才會(huì)去找后一個(gè)；而我們想要的效果是：當(dāng)a.jar在第一個(gè)mirror中不存在的時(shí)候，maven會(huì)去第二個(gè)mirror中查詢下載，但是maven不會(huì)這樣做！
properties作用：對(duì)應(yīng)profile的擴(kuò)展屬性列表。maven屬性和ant中的屬性一樣，可以用來存放一些值。這些值可以在pom.xml中的任何地方使用標(biāo)記${X}來使用，這里X是指屬性的名稱。屬性有五種不同的形式，并且都能在settings.xml文件中訪問。
<!-- 1. env.X: 在一個(gè)變量前加上"env."的前綴，會(huì)返回一個(gè)shell環(huán)境變量。例如,"env.PATH"指代了$path環(huán)境變量（在Windows上是%PATH%）。 2. project.x：指代了POM中對(duì)應(yīng)的元素值。例如: <project><version>1.0</version></project>通過${project.version}獲得version的值。 3. settings.x: 指代了settings.xml中對(duì)應(yīng)元素的值。例如：<settings><offline>false</offline></settings>通過 ${settings.offline}獲得offline的值。 4. Java System Properties: 所有可通過java.lang.System.getProperties()訪問的屬性都能在POM中使用該形式訪問，例如 ${java.home}。 5. x: 在<properties/>元素中，或者外部文件中設(shè)置，以${someVar}的形式使用。 --><properties> <user.install>${user.home}/our-project</user.install></properties>
