>          Key: BEEHIVE-37
>          URL: http://issues.apache.org/jira/browse/BEEHIVE-37
>      Project: Beehive
>         Type: Improvement
>  Environment: ant less than 1.6, jdk less than 1.5
>     Reporter: bob mcwhirter
>      Fix For: V1Beta

> Will submit a patch.  Just noting it here for progress tracking.
> running ant from the top-level of the build should check and gracefully fail if the current version of ant and/or the jdk is not sufficient to build beehive.
> There is only 1 construct in the current top-level build that isn't supported by older versions of ant, being the <fail> with a nested <condition>.  The ant manual itself shows a different way of using <condition> to set a property followed by a <fail unless="..."> idiom, instead of the nesting.  I've confirmed that this idiom does indeed work with older (more common) versions of ant.
> Suggested verbiage from my localhost...
> for failing JDK version check:
>       <fail unless="jdk.version.okay">
>         Newer JDK required.
>         Building the project requires JDK 1.5.
>         You are currently using the following JDK:
>             java.home    = ${java.home}
>             java.version = ${java.version}
>             java.vendor  = ${java.vendor}
>         You may obtain a newer version of the JDK from 
>             http://java.sun.com/
>         If you have JDK 1.5 installed on your system, you may need to 
>         adjust your JAVA_HOME environment variable.
>       </fail>
> for failing ant version check
>       <fail unless="ant.version.okay">
>         Newer Ant required.
>         Building the project requires apache-ant 1.6.
>         You are currently using the following apache-ant:
>       
>             ant.home    = ${ant.home}
>             ant.version = ${ant.version}
>         You may obtain a newer version of ant from 
>             http://ant.apache.org/
>         If you have ant 1.6 installed on your system, you may need to 
>         adjust your ANT_HOME environment variable.
>       </fail>
