Subject [jira] Commented: (KARAF-405) Force JDK 1.5 compiler
Date Thu, 20 Jan 2011 08:55:44 GMT

    [ https://issues.apache.org/jira/browse/KARAF-405?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12984096#action_12984096
] 

Achim Nierbeck commented on KARAF-405:
--------------------------------------

If you work with eclipse (together with m2eclipse plugin), the sourc/target flags already
help a lot. 
This way the eclipse project is configured to use JDK5 and the eclipse compiler starts complaining
:)

>                 URL: https://issues.apache.org/jira/browse/KARAF-405
>             Project: Karaf
>          Issue Type: Improvement
>            Reporter: Jean-Baptiste Onofré
>             Fix For: 2.2.0

> As agreed on the dev mailing list, we defined the following policy:
> - Karaf 2.2.x == JDK 1.5
> - Karaf 3.0.x == JDK 1.6
> It means that we should be sure that we don't use JDK 1.6 specific methods on the current
trunk (corresponding to Karaf 2.2.x).
> For instance, we got a Hudson build failure due to the usage of java.lang.String isEmpty()
method which is JDK 1.6 specific whereas Hudson still uses JDK 1.5.
> To detect this kind of situation, I propose to define the <source/> and <target/>
on the maven-compiler-plugin.
> These instructions will be removed after the 2.2.x branch cut off. The trunk will be
Karaf 3.0.x and so JDK 1.6 compliant.
