Maven：范围值无效

Question

找不到相关的文档：

使用“自定义”范围声明依赖项时会发生什么：

    <dependency>
        <groupId>group</groupId>
        <artifactId>artifact</artifactId>
        <version>1.0</version>
        <scope>whatever</scope>
    </dependency>

没有检查，这个没有失败：

dependency:tree

[INFO] +- group:artifact:jar:1.0:whatever

...疯狂

Answer 1

Maven 3中的Pom验证得到了显着改善：这是MNG-3991以来的警告：

[WARNING] 'dependencies.dependency.scope' for junit:junit:jar must be one of [provided, compile, runtime, test, system] but is 'xxxx'. @ line 27, column 11
[WARNING] 
[WARNING] It is highly recommended to fix these problems because they threaten the stability of your build.
[WARNING] 
[WARNING] For this reason, future Maven versions might no longer support building such malformed projects.

正如问题所述，即使在Maven 3中，它仍然只是一个警告，而不是失败：

  

这是对使用自定义依赖范围的Flex Mojos等扩展进行反向竞争的妥协。
