Hi,

In my honest opinion it does, in case you want to switch from artifacts
that belong to a migrated groupid.


It may have sense, but it is very corner case.
I have never seen such cases.

It would be interesting to have some 'exclude * except ...'

Like
<exclusion>
<groupid>io.netty</groupid>
<artifactId>* but keep netty-all<artifactId>
</exclusion>

I don't think we should do something like this. In Maven we have includes to define a set of dependencies and excludes to remove some specific dependencies. Adding another layer would overcomplicate things.

Instead, people could do:
<dependency>
 <groupId>GROUPID</groupId>
 <artifactId>ARTIFACT</artifactId>
 <exclusions>
  <exclusion>
  <groupid>io.netty</groupid>
  <artifactId>*<artifactId>
  </exclusion>
 </exclusions>
</dependency>
<dependency>
 <groupId>io.netty</groupId>
 <artifactId>netty-all</artifactId>
</dependency>


Netty is famous for shipping a uber netty-all and a ten of netty-codec,
netty-common...artifacts and it is always a mess to keep clean the
dependency tree in case of multiple consumers of such library in different
flavours (uber vs split)

Sorry for beeing slightly off topic

I will review the patch

Enrico



Thanks,
Alexius
