我们有一个网关客户端项目，它是多模块maven项目的一部分。 gateway-client pom.xml配置为创建两个主要工件：gateway-client.jar和gateway-services-client.jar，并将它们部署到两个独立的Nexus存储库：Releases repo和第三方repo。这是通过默认激活的配置文件完成的：
<profile>
<!-- ====================================================================== -->
<!-- default Profile -->
<!-- This is the default profile which will run by default. This profile -->
<!-- produces two client artifacts: gateway-client and gateway-services-client -->
<!-- for the releases and thirdparty repositories respectively. -->
<!-- ====================================================================== -->
<id>default</id>
<activation>
<activeByDefault>true</activeByDefault>
</activation>

问题在于，因为默认情况下此配置文件处于活动状态，如果我们尝试运行mvn deploy并且GAV坐标版本为-SNAPSHOT，则构建无意中仍会尝试部署到Nexus 3rd Party和发布repos并失败，因为它当然不会接受-SNAPSHOT工件版本。为了解决这个问题，我专门针对-SNAPSHOT版本设置了一个配置文件，该版本只会部署到Snapshot存储库：
<profile>
<!-- ====================================================================== -->
<!-- snapshot Profile -->
<!-- Activating this profile will automatically deactivate the default profile. -->
<!-- The purpose of this profile is to produce a a gateway-services-client and gateway-client -->
<!-- snapshot artifacts and deploy them to the snapshots Nexus repository where they can -->
<!-- act as the latest development dependencies for other projects -->
<!-- ====================================================================== -->
<id>snapshot</id>
<activation>
<activeByDefault>false</activeByDefault>
</activation>
<!-- ====================================================================== -->
<!-- snapshot profile Build plugins -->
<!-- ====================================================================== -->

<!-- ====================================================================== -->
<!-- snapshot profile Maven deploy plugin -->
<!-- ====================================================================== -->

这个问题是您必须在执行Maven命令时指定配置文件：mvn deploy -P 'snapshot'。我的问题是我能做什么，以便我所要做的就是运行mvn deploy而不指定快照配置文件，并让构建自动部署到快照存储库或第三方和发布存储库，所有这些都基于前提-GNAPSHOT在GAV坐标的版本中？

我想到的唯一解决方案是在部署期间使用属性并添加三个执行。丑陋的是，在SNAPSHOT的情况下，您的工件将被部署到同一个存储库两次。
以下是您可以做的事情：
<plugin>
<groupId>org.codehaus.groovy.maven</groupId>
<artifactId>gmaven-plugin</artifactId>
<version>1.0</version>
<executions>
<execution>
<id>eval-repo</id>
<phase>initialize</phase>
<goals>
<goal>execute</goal>
</goals>
<configuration>
<source>
if (project.version.endsWith("-SNAPSHOT")){
project.properties.repoId = "snapshots";
project.properties.repoUrl = "snapshots url";
project.properties.thirdPartyRepoId = "snapshots";
project.properties.thirdPartyRepoUrl = "snapshots url";
}
else {
project.properties.repoId = "releases";
project.properties.repoUrl = "releases url";
project.properties.thirdPartyRepoId = "thirdparty";
project.properties.thirdPartyRepoUrl = "thirdparty url";
}
</source>
</configuration>
</execution>
</executions>
</plugin>
然后使用以下配置添加三个执行：
<configuration>
<artifactId>gateway-client</artifactId>
<url>${repoUrl}</url>
<repositoryId>${repoId}</repositoryId>
...
<configuration>
<artifactId>gateway-services-client</artifactId>
<url>${repoUrl}</url>
<repositoryId>${repoId}</repositoryId>
...
<configuration>
<artifactId>gateway-services-client</artifactId>
<url>${thirdPartyRepoId}</url>
<repositoryId>${thirdPartyRepoUrl}</repositoryId>
...

您不能使用个人资料。来自maven doc：
可以通过多种方式触发/激活个人资料：
- 显式
- 通过Maven设置
- 基于环境变量
- 操作系统设置
- 出现或丢失文件
所以你不能按照你想要的方式去做。但是，我们一直这样做。我们的设置是在超级pom中使用以下内容
<distributionManagement>
<repository>
<id>deploymentRepo</id><!-- key in settings.xml -->
<name>Releases</name>
<uniqueVersion>false</uniqueVersion>
<url>${repos.release}</url>
<layout>default</layout>
</repository>
<snapshotRepository>
<id>deploymentRepo</id>
<name>Snapshots</name>
<uniqueVersion>true</uniqueVersion>
<url>${repos.snapshot}</url>
<layout>default</layout>
</snapshotRepository>
</distributionManagement>
注意id是相同的，因为两个repos都使用相同的凭证。
我们也在使用nexus将每个repo配置为快照或版本，只需这样，maven就能知道* -SNAPSHOT会转到快照仓库。
换句话说，只要同时给出两个选项，不要将它们放在互斥的配置文件中，maven就会知道发送它们的方式。如果没有，请尝试回购经理
