Ian Springer commented on MNG-4226:
-----------------------------------
When you run "java -version", the shell is going to run the first java
executable it finds in your PATH, which may not be the same as the java the mvn
shell script uses, which is:
1) if JAVA_HOME defined: $JAVA_HOME/bin/java
2) else if /System/Library/Java/JavaVirtualMachines/CurrentJDK exists:
/System/Library/Java/JavaVirtualMachines/CurrentJDK/Contents/Home/bin/java
What is your PATH set to? You can also try running "whereis java".

> Key: MNG-4226
> URL: https://jira.codehaus.org/browse/MNG-4226
> Project: Maven
> Issue Type: Improvement
> Components: Command Line
> Reporter: Alin Dreghiciu

> On mac JAVA_HOME is detected by using the following code:
> {code}
> if [ -z "$JAVA_VERSION" ] ; then
> JAVA_VERSION="CurrentJDK"
> else
> echo "Using Java version: $JAVA_VERSION"
> fi
> if [ -z "$JAVA_HOME" ] ; then
>
> JAVA_HOME=/System/Library/Frameworks/JavaVM.framework/Versions/${JAVA_VERSION}/Home
> fi
> {code}
> But this does not work in collaboration with Using "Java preferences" to
> change the actual java version to use as "CurrentJDK" does not change once
> you update the "java applications" order.
> There is an alternative (at least on Leopard) for determining current java
> home that is based on Java Preferences by using an apple provided script. So,
> as a replacement fo rthe code above the following could be used.
> {code}
> if [ -z "$JAVA_HOME" ] ; then
> JAVA_HOME=`/usr/libexec/java_home | tail -1`
> fi
> {code}
> Could also be taht this is teh first attempt and if fails use the current way
> of determining home.
