How change build options in netbeans

Question

I have a project in netbeans in which I have a java scanner which has been generated using jflex. So when I usually build this using a make file I use the -Xlint option, that is

javac -Xlint javaScanner.java

But now when I am creating the jar file using the clean and build option it is showing the following error.

init:
deps-clean:
Updating property file: /home/mridula/testPrjct/sDvait-LCS/build/built-clean.properties
Deleting directory /home/mridula/testPrjct/sDvait-LCS/build

To run this application from the command line without Ant, try:
java -jar "/home/mridula/testPrjct/sDvait-LCS/dist/sDvait-LCS.jar"

If I could know how the file is being built. I could just add the -Xlint option so that the jar file could be created without a problem.

Netbeans uses ant to build java projects. There is a build.xml file in your project dir that handles this process.

But you have another option:

Right click your project node, choose "Properties" (a dialog box pops up). On the left choose "Compiling" and add your options in the field "Additional compiler options"
