Does this mean ant is calling some java api to the compiler and uses
$JAVA_HOME as the jar files for the compiler?
Yes, Ant acquires the main compiler class by reflection. See
org.apache.tools.ant.taskdefs.Javac13 if you're interested.
(My situation is that JAVA_HOME does not match the JDK 1.4.2 I have
setup in my ant.properties and I'm wondering which compiler is being
used.)
It's whatever JDK is being used to invoke Ant. The easiest way to
determine that is by running 'ant -verbose', it will be third line of
output. Depending on how you invoke ant, it might not be what is in
your PATH or JAVA_HOME. E.g. if you install Apple's Java developer
tools on Mac OS X, then running 'ant' in the shell invokes whatever is
the current base JDK level for Mac OS X, and is not what is in your
PATH or even in JAVA_HOME.
Thanks Andrew.
Does that mean that this section from Derby's BUILDING.txt is not required.
------------------
(3) Create environment variable JAVA_HOME to point to the
directory where you have installed JDK 1.4.x. For example:
setenv JAVA_HOME ${jdk14.dir} -- On unix(csh).
export JAVA_HOME=${jdk14.dir} -- On unix(ksh)
set JAVA_HOME=${jdk14.dir} -- On Windows
-------------------
If it is required, what does it affect?
Thanks,
Dan.
