我必须使用maven构建一个war文件来有条件地包含jar, 每个jar都是由一个单独的maven项目创建的,该项目将jar部署到nexus(我们的组织远程)存储库
例如:我有像这些core.jar,reward.jar,payment.jar,domains.jar这样的罐子等等 我需要建立一个基于条件(environmnet)的最终战争,以包括上面的罐子
最后战争的组合(w1) w1.war:core.jar,domains.jar w1.war:core.jar,domains.jar,rewards.jar(如果奖励适用,可以指定包含此jar的任何方式)

Maven WAR Plugin允许您包含/排除JAR。例如:
<plugin>
<artifactId>maven-war-plugin</artifactId>
<version>3.1.0</version>
<configuration>
<packagingExcludes>
WEB-INF/lib/excluded.jar
</packagingExcludes>
<packagingIncludes>
WEB-INF/lib/included.jar
</packagingIncludes>
</configuration>
</plugin>
您可以使用配置文件将包含/排除与条件相关联。例如,让WAR插件使用属性($ {excludedResources},$ {includedResources})...
<plugin>
<artifactId>maven-war-plugin</artifactId>
<version>3.1.0</version>
<configuration>
<packagingExcludes>
${excludedResources}
</packagingExcludes>
<packagingIncludes>
${includedResources}
</packagingIncludes>
</configuration>
</plugin>
...并通过配置文件定义这些属性的值:
<profiles>
<profile>
<id>prod</id>
<properties>
<excludedResources>WEB-INF/lib/a.jar,WEB-INF/lib/b.jar</excludedResources>
<includedResources>WEB-INF/lib/c.jar</includedResources>
</properties>
</profile>
<profile>
<id>tst</id>
<properties>
<excludedResources>WEB-INF/lib/x.jar,WEB-INF/lib/y.jar</excludedResources>
<includedResources>WEB-INF/lib/z.jar</includedResources>
</properties>
</profile>
</profiles>
因此,您可以使用Maven WAR Plugin的内置功能来调整WAR内容,并且可以使用Maven配置文件使这些调整成为条件。

您可以尝试在maven中使用profiles
功能。每个依赖关系可以包括在其自己的简档块中,例如仅当您通过domains
个人资料切换此个人资料和服务时,才会包含services
。
同时,您可以通过公共依赖块识别公共jar(在我们的例子中core.jar
将是常见的)

激活的命令行可以是:
此命令行将包含core.jar和domains.jar
mvn clean install -Pdomains
在这种情况下,war将包括core.jar和services.jar
mvn clean install -Pservices
最后通过此命令行将包含所有jar
mvn clean install -Pdomains,services
