Hi,
I know that using <javac ..... executable=<PATH TO JAVAC>
I can specify the javac that I want to use for a compilation but is it
possible to do this the other way round?
I.e., I want to explicitly specify to Ant the runtime to use for itself at
startup (one which it won't find as default in the $PATH) and then use the
default javac for the compilation itself.
lets think about this for a minute.
you want an option, presumably something like -runtime=1.4 or
-runtime=/usr/share/java/1.4 which ant (a java program) will use to
determine the runtime it runs under.
i.e. you want a java program to be able to dynamically decide which
runtime to run under.
This isnt possible. Which leaves making changes to the java startup
scripts. Those scripts are scary and complex enough as it is, believe
me, and they lead to many more support calls than 200 lines of code
ought to, especially from systems/configurations you dont expect to be
running Ant.
Its much easier just to edit the path. Have some script that changes
your JAVA_HOME, JDK_HOME, PATH env options for a particular shell; run
that in whichever shell you want to call ant from later.
