准备工作使用前请确保您已安装JDK及Maven。如果您尚未安装,可以点击下面链接下载安装:JDK官网下载地址:
https://www.oracle.com/technetwork/java/javase/downloads/index.htmlMaven加速地址:https://repo.huaweicloud.com/apache/maven/maven-3/
使用说明点击此处 下载settings.xml文件,覆盖<Maven安装目录>/conf/settings.xml文件即可。如果您不想覆盖配置文件,可以手动在settings.xml文件中的mirrors节点中添加如下内容:
<mirror> <id>huaweicloud</id> <mirrorOf>*</mirrorOf> <url>https://repo.huaweicloud.com/repository/maven/</url></mirror>

https://maven.apache.orgMaven搜索地址:http://mvnrepository.com
1.在mirrors节点中添加如下配置:(可选,使用华为开源镜像站加速下载开源组件)
<mirror> <id>z_mirrors</id> <mirrorOf>*,!releases,!snapshots</mirrorOf> <url>https://repo.huaweicloud.com/repository/maven/</url> </mirror>
2.在servers节点中添加如下配置:(password从下载的settings.xml文件中获取)
<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节点中添加如下配置
<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>
打开maven的配置文件(windows机器一般在maven安装目录的conf/settings.xml),在<mirrors></mirrors>标签中添加mirror子节点:
<mirror> <id>aliyunmaven</id> <mirrorOf>*</mirrorOf> <name>阿里云公共仓库</name> <url>https://maven.aliyun.com/repository/public</url></mirror>
如果想使用其它代理仓库,可在<repositories></repositories>节点中加入对应的仓库使用地址。以使用spring代理仓为例:
<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节点中添加如下配置:(可选,使用阿里开源镜像站加速下载开源组件)
<mirror> <id>mirror</id> <mirrorOf>!rdc-releases,!rdc-snapshots</mirrorOf> <url>https://maven.aliyun.com/repository/public</url> </mirror>
在settings.xml中添加认证信息
在Maven的的默认settings.xml中找到servers的部分,添加一个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节点添加如下配置, 其中 repository 是顺序搜索下载包的.
<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>
制品上传配置
配置好了settings.xml后,在代码库根目录下的pom.xml加入以下配置:
<!-- 需要发布二方包 则打开下列的配置 --><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>
然后运行以下命令即可将制品推送到私有仓库中:
$ mvn clean deploy -DskipTests
Maven中-DskipTests和-Dmaven.test.skip=true的区别在使用mvn package进行编译、打包时,Maven会执行src/test/java中的JUnit测试用例,有时为了跳过测试,会使用参数-DskipTests和-Dmaven.test.skip=true,这两个参数的主要区别是:
-DskipTests,不执行测试用例,但编译测试用例类生成相应的class文件至target/test-classes下。-Dmaven.test.skip=true,不执行测试用例,也不编译测试用例类。
虽然mirrors可以配置多个子节点,但是它只会使用其中的一个节点,即默认情况下配置多个mirror的情况下,只有第一个生效,只有当前一个mirror无法连接的时候,才会去找后一个;而我们想要的效果是:当a.jar在第一个mirror中不存在的时候,maven会去第二个mirror中查询下载,但是maven不会这样做!
properties作用:对应profile的扩展属性列表。maven属性和ant中的属性一样,可以用来存放一些值。这些值可以在pom.xml中的任何地方使用标记${X}来使用,这里X是指属性的名称。属性有五种不同的形式,并且都能在settings.xml文件中访问。
<!-- 1. env.X: 在一个变量前加上"env."的前缀,会返回一个shell环境变量。例如,"env.PATH"指代了$path环境变量(在Windows上是%PATH%)。 2. project.x:指代了POM中对应的元素值。例如: <project><version>1.0</version></project>通过${project.version}获得version的值。 3. settings.x: 指代了settings.xml中对应元素的值。例如:<settings><offline>false</offline></settings>通过 ${settings.offline}获得offline的值。 4. Java System Properties: 所有可通过java.lang.System.getProperties()访问的属性都能在POM中使用该形式访问,例如 ${java.home}。 5. x: 在<properties/>元素中,或者外部文件中设置,以${someVar}的形式使用。 --><properties> <user.install>${user.home}/our-project</user.install></properties>
