working with several java version with maven

[Adva Rotstein-Hayun <ar...@jacada.com>]

Hi,
I have several projects that compile with java 5.
There is 1 project I would like to compile with java 6.
I added to that project pom the source and target attributes, however my JAVA_HOME environment variable is set to java 5.
How can I tell maven where is my java 6 home?
I can not change my JAVA_HOME on each run, I would like it to be automatically.
Can I define it in a pom.xml?

We would manage this in our CI server and indeed control what JAVA_HOME
is set to for different workflows. We'd further use Maven profiles to
toggle the setting within Maven for things like compiler settings. Then
one code change could trigger two builds in parallel targeting different
JDK's.

There is also Toolchains!

http://maven.apache.org/guides/mini/guide-using-toolchains.html

Of course not many people know about Toolchains, but for Java it does
actually work!

You can run Maven under java6 and tell it that the target language
level is 1.5 by configuring the maven-compiler-plugin. You can also
use the animal sniffer to detect accidental use of 1.6 APIs in a 1.5
environment.
