> I'm developing an extension in a continuous build environment and Maven doesn't even attempt to download the extension if the entry in .mvn/extensions.xml has a -SNAPSHOT version. It simply fails with a warning that it could not find the extension without explaining why it didn't try to download it. This means that in order for me to try out the extension, I have either have to build it locally or make a release first. I've been unable to find any documentation that identifies this as an intentional limitation, which leads me to believe it must be a bug.
> For example, my extension allows the pom.xml to be written in a Kotlin DSL. Because my pom is named pom.kts instead of pom.xml, my build will fail if it cannot download the extension as defined below:
> {code:xml}
> <?xml version="1.0" encoding="UTF-8"?>
> <extensions>
>   <extension>
>     <groupId>io.takari.polyglot</groupId>
>     <artifactId>polyglot-kotlin</artifactId>
>     <version>0.3.3-SNAPSHOT</version>
>   </extension>
> </extensions> 
> {code}
> However, if I change the version to a non-snapshot, Maven does attempt to download the extension:
> {code:xml}
> <?xml version="1.0" encoding="UTF-8"?>
> <extensions>
>   <extension>
>     <groupId>io.takari.polyglot</groupId>
>     <artifactId>polyglot-kotlin</artifactId>
>     <version>0.3.3.beta01</version>
>   </extension>
> </extensions> {code}
> It seems to me that Maven should attempt to resolve the extension regardless of whether it is a snapshot or not because my plugin repository in settings.xml has been configured to allow snapshots.
