HI there,

When I compile my project using ANT the compiler states the following:

			

			compile:
			

			

			[javac] Compiling 2 source files to :Scholastic_Hibernate uildclasses
			

			

			[javac] Note: C:Scholastic_HibernatesrcjavascholasticmodelsCompany.java
			

			uses unchecked or unsafe operations.
			

			

			[javac] Note: Recompile with -Xlint:unchecked for details.

My build.xml file has the following:

destdir="${build.classes.dir}"

classpathref="project.classpath"/>

Is there an attribute for the javac tag that forces compilation with the switch -Xlint:unchecked? I need to get the details from the compiler so that I can fix the problem.

I think you use a nested "compilerarg" element, something like . With that said, this probably relates to 1.5 generics stuff; you can just compile the class on your own (outside of ant) with the -X... arg to see the message, and you can likely suppress the compiler from giving you this message at all using the appropriate annotation, probably in this case by putting @SuppressWarnings("unchecked") on either the class as a whole or on just the troublesome method(s) it/themselves.
