Have Java code output Java version, not the shell script
--------------------------------------------------------
Key: MNG-2376
URL: http://jira.codehaus.org/browse/MNG-2376
Project: Maven 2
Type: Improvement
Components: Command Line
Versions: 2.0.4
Environment: Mac OS X 10.4
Reporter: David Smiley
Priority: Minor
The shell script outputs $JAVA_VERSION. In my case, in an ill-fated attempt to
get maven to use JDK 1.4, this was set to 1.4 but JAVA_HOME was already set (in
.profile or wherever) to that of the current JDK (1.5). So it is inconsistent
and led me on a wild goose chase to track down a problem. If Maven is going to
output the java version, do it from java code using the right system property.
Only use JAVA_VERSION to help select a JAVA_HOME, if JAVA_HOME isn't set.
Perhaps there is some standard approach to this sort of thing but I am unsure.
