In Ant:
(How i use it: put project.correct.java.version=[Major].[Minor])
<!-- ==================================================
Check for correct java version
================================================== -->
<preGoal name="java:compile">
<echo message="Current Java Version is:
${java.specification.version} and should be:
${project.correct.java.version}"/>
<!-- set property if the version is correct -->
<condition property="java.version.is.correct">
<!-- Property explanation: -->
<!-- Less detailled version = java.specification.version (1.2)
-->
<!-- More Detailled version = java.version (1.2.1_02) -->
<equals arg1="${project.correct.java.version}"
arg2="${java.specification.version}" />
</condition>
<fail unless="java.version.is.correct" message="Incorrect java
version" />
</preGoal>
There are always several ways for the same ;->
