Subject RE: set jvm to 1.3
Date Fri, 18 Mar 2005 07:20:33 GMT
Hi,

I have set javac's  source attribute  to 1.3 but when I compile the code I get,

".. warning: as of release 1.4, assert is a keyword..."

I start ant with 1.4.2 so I guess that is the default for compiling code to.
As I understand it the javac command with option '-source 1.3' would make the 1.4 compiler
to compile for 1.3?! 

This is what I use in my build.xml

<javac  debug="true" deprecation="true" destdir="${classes.dir}" 
         srcdir="${src.dir}" source="${BUILD.COMPILER}">

Any ideas why?

AFAIK, target means to what version of class format
must the compiled classes conform to; compiler means
what compiler exactly should be used for compilation
(i.e. to produce these classes).
