Joerg Schaible commented on MNG-1957:
-------------------------------------
Guys, please take into account that you probably do not get what you try to
reach. Especially Edwin's use case will not work. By declaring different
dependencies in profiles that are automatically activated based on the used JDK
you all implicitly assume that this is also the target JDK. This assumption is
false! Have a look at the error reports in MNG-3957 caused by such profiles in
spring-core-ws and XStream. Both POMs declare different deps depending on the
JDK. If a client now declares a different target JDK than the one he uses to
run Maven, he gets the wrong transitive dependencies.
> <jdk></jdk> clause in the activation section has to provide more complex
> expressions.

> For now, <jdk></jdk> provides only one operator '!' which means negation, but
> it would be great if i can use '+' and ~ operator:
> <jdk>1.5+</jdk> <!-- this will be activated when the current JDK version is
> 1.5 or above (e.g. 1.6) -->
> <jdk>1.1 ~ 1.4</jdk> <!-- this will be activated when the current JDK version
> is between 1.1 and 1.4 -->
> <jdk>~ 1.3</jdk> <!-- this will be activated when the current JDK version is
> 1.3 or below -->
> <jdk>1.4 ~</jdk. <!-- the same with 1.5+ -->
