Just make sure all the tools you might need are found. I suggest a regular housekeeping of the PATH environment variable. For example, Android devs may wish to include $ANDROID_HOME/tools and $ANDROID_HOME/platform-tools. Java developers need $JAVA_HOME/bin. Of course, $ANDROID_HOME and $JAVA_HOME must point to the installation directories of the Android SDK and the Java Development Kit.
NetBeans offers a Terminal window, too.
There is a plugin called Terminal Extras. It helps setting a base directory upon invocation of the Terminal. You can download it through the Plugin Manager.
Just pick a project and hit Alt-.
Simple yet great.
