Maven的：无效的范围值

Question

无法找到相关文档：

什么，当你与声明“自定义”范围的依赖情况：

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

有没有检查，这一个不失败：

dependency:tree 

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

疯狂......

Answer 1

双响炮验证在Maven的3显著改善：这是因为一个警告MNG-3991：

[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. 

由于这个问题指出，即使是在Maven的3它仍然只是一个警告，而不是失败：

这是一种妥协，以保持向后compat的就是那样的使用Flex Mojos扩展自定义依赖范围。
