Subject RE: Which javac does ant use in its "javac" task?
Date Wed, 16 Jan 2013 01:40:15 GMT
Thank you.  I presume this is answer to my first question - Which javac does ant use? Is it
in the ANT code that doesn't process the wildcard classpath?  Is this javac class a java compiler
class, or just a class that defines ANT's javac task ?   If it is a compiler, then does it
mean that ANT's javac is having trouble dealing with wildcard classpaths then?

Then, What role does JAVA_HOME play when using ANT?

Thanks again.

you will find a javac key in .\org\apache\ant\taskdefs\default.propertiesjavac=org.apache.tools.ant.taskdefs.Javac
defaults.properties is wholly contained within ant.jar inside $ANT_HOME\lib\ant.jar
