build.xml should fail gracefully with info if using invalid ant or jdk versions
-------------------------------------------------------------------------------
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
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You may obtain a newer version of the JDK from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>
