最佳实践
关于配置settings.xml和pom.xml的最佳实践
* pom优先于settings
* 原则上我们都使用pom来进行配置，避免因为每个开发者本地的settings不同而有所差异，`<profiles>`配置在pom中而不是settiings中
* 公司管理非公共jar的方式有两种：
* 一种是不区分环境
* 一种是区分环境，比如dev，test，stg，prd等
* 对于不分区环境的，我们一个mirror全部从公共私服（镜像）拉取即可，这样所有请求都走公司私服，速度比较快，这种是应对新建项目未配置pom时候，则正常情况下所有的项目均应该配置pom，比如
<mirror> <id>nexus</id> <name>公司私服</name> <url>http://nexus.xxx.xxx/repository/maven-public</url> <mirrorOf>*</mirrorOf> </mirror>
* 对于分环境的，我们将各种环境的的仓库走各个环境的仓库，其他的都走公共私服，如下所示。这样的好处是：
* 当某个项目并没配置profiles时候走的是公共仓库
* 当某个项目配置了profiles时候走的是对应的仓库，当新建项目时候由于pom未配置也会走私服，比较快
* 当有新的环境增加时在下方的mirrorOf中增加`!xxx`即可
<mirror> <id>nexus</id> <name>公司私服</name> <url>http://nexus.xxx.xxx/repository/maven-public</url> <mirrorOf>*,!xxx-dev,!xxx-qa,!xxx-pre,!xxx-stg!,xxx-prd</mirrorOf> </mirror>
* 对于profile的配置建议（只需要发布到私服）：
<!-- 环境信息，mvn clean source:jar deploy -P ${env}，也可通过idea的mvn插件勾选对应环境进行deploy --> <!-- 这里的id就是上面${env}替换的值 --> <!-- <id>,<profileActive>设置成相同的值 --> <!-- distributionManagement.snapshotRepository和distributionManagement.repository和repositories.repositorie.id的id设置成mirror中排除的名称，这样一来拉去jar包从指定的${id}(也就是${env})中拉去，deploy时候也是deploy到指定的${id}(也就是${env})中去 --> <!-- 如果使用flatten插件需要全局禁用deploy插件，并且在需要deploy的模块中增加<profile>启用deploy插件，对于不需要deploy的模块不需要配置<distributionManagement> --> <!-- <repositories>放在父pom的profile中，因为需要从不同环境拉去jar包 --> <profiles> <profile> <id>dev</id> <activation> <activeByDefault>true</activeByDefault> </activation> <properties> <profileActive>dev</profileActive> </properties> <repositories> <repository> <releases> <enabled>true</enabled> </releases> <snapshots> <enabled>true</enabled> <updatePolicy>always</updatePolicy> </snapshots> <id>xxx-dev</id> <url>http://nexus.xxx.xxx/repository/xxx-dev-public/</url> </repository> </repositories> </profile> </profiles> <!-- <distributionManagement>放在需要deploy的子模块中，由于父pom全局禁用了deploy，所以这里还需要开启 --> <profiles> <profile> <id>dev</id> <activation> <activeByDefault>true</activeByDefault> </activation> <properties> <profileActive>dev</profileActive> </properties> <distributionManagement> <snapshotRepository> <id>xxx-dev</id> <name>xxx-dev</name> <url>http://nexus.xxx.xxx/repository/xxx-dev/</url> <uniqueVersion>false</uniqueVersion> </snapshotRepository> </distributionManagement> <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-deploy-plugin</artifactId> <configuration> <skip>false</skip> </configuration> </plugin> </plugins> </build> </profiles>
* 对于profile的配置建议（既要发布到私服又要发布到中央库的项目），使用flattern插件的情况：
* maven-deploy-plugin插件全局禁用deploy
* 将repositories配置在父pom中，实现所有子模块继承（由于都从私服拉去，repositories无需配置profile，只需要将distributionManagement配置在profile中即可）
* 由于私服和公共仓库的
* 将distributionManagement分别设置在子模块中，便于deploy，全部如下：
<!-- repositories放在父pom中，并且无需放在profile中，因为都是从私服下载 --> <repositories> <repository> <id>nexus</id> <url>http://nexus.xxx.xxx/repository/maven-public/</url> <releases> <enabled>true</enabled> </releases> <snapshots> <enabled>true</enabled> <updatePolicy>always</updatePolicy> </snapshots> </repository> </repositories> <!-- profiles分别放在需要deploy的子模块中 --> <profiles> <profile> <id>nexus</id> <activation> <activeByDefault>true</activeByDefault> </activation> <distributionManagement> <repository> <id>nexus</id> <url>http://nexus.xxx.xxx/repository/maven-releases/</url> </repository> <snapshotRepository> <id>nexus</id> <url>http://nexus.xxx.xxx/repository/maven-snapshots/</url> </snapshotRepository> </distributionManagement> <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-deploy-plugin</artifactId> <configuration> <skip>false</skip> </configuration> </plugin> </plugins> </build> </profile> <profile> <id>oss</id> <distributionManagement> <repository> <id>oss</id> <url>https://oss.sonatype.org/content/repositories/snapshots</url> </repository> <snapshotRepository> <id>oss</id> <url>https://oss.sonatype.org/content/repositories/snapshots</url> </snapshotRepository> </distributionManagement> <build> <plugins> <plugin> <groupId>org.sonatype.plugins</groupId> <artifactId>nexus-staging-maven-plugin</artifactId> <version>1.6.8</version> <extensions>true</extensions> <configuration> <serverId>ossrh</serverId> <nexusUrl>https://oss.sonatype.org</nexusUrl> <autoReleaseAfterClose>true</autoReleaseAfterClose> </configuration> </plugin> </plugins> </build> </profile> </profiles>
