[jira] Commented: (MNG-1957) clause in the activation section has to provide more complex expressions.

    [ http://jira.codehaus.org/browse/MNG-1957?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_88731 ] 

Edwin Punzalan commented on MNG-1957:
-------------------------------------

I like this and am voting for it.  This is useful for instances like javax.management being already available in JDK 1.5 so you'll want to put the dependency for it and its implementation when the JDK is "~ 1.5".

> 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+ -->
