How can I run/debug a program in NetBeans with certain environment variables set to necessary values?
(For example I often need to debug programs with the $DISPLAY variable set.)
A: you will need to copy the -init-macrodef-java and/or -init-macrodef-debug targets into build.xml from build-impl.xml and add one or more <env> parameters. See: Ant documentation for <java>
Be sure to uncheck Compile on Save in the Compiling tab of the project properties dialog.
Note: Ant does not currently provide the necessary machinery for you to configure these from a properties file. See: Ant bug #40448
