Re: Building files with different jdk versions

[Eric Redmond <er...@gmail.com>]

You probably should separate your project into different projects each
containing the set of files you want, allowing each one to use it's own
compiler:

http://maven.apache.org/plugins/maven-compiler-plugin/examples/compile-using-different-jdk.html

Or if you can get away with it (which most people can), just using the
higher version compiler and setting the lower target/source for the lower
projects (eg, use javac 1.5 always, but set target as 1.4 when necessary).

http://maven.apache.org/plugins/maven-compiler-plugin/examples/set-compiler-source-and-target.html

However  if you reeeeaallly need to keep the files in a single project, put
the set of "some files" you described into a separate directory - and
include that directory using this:

http://mojo.codehaus.org/build-helper-maven-plugin/howto.html

Called under a profile:

Isn't diverging from the standard fun?  ;-P
