+<!-- You may freely edit this file. See commented blocks below for -->
+<!-- some examples of how to customize the build. -->

+<!-- By default, only the Clean and Build commands use this build script. -->
+<!-- Commands such as Run, Debug, and Test only use this build script if -->

+<!-- You can turn off the Compile on Save (or Deploy on Save) setting -->

+ <import file="nbproject/build-impl.xml"/>
+ <!--
+
+ There exist several targets which are by default empty and which can be
+ used for execution of your tasks. These targets are usually executed
+ before and after some main targets. They are:
+
+ -pre-init: called before initialization of project properties
+ -post-init: called after initialization of project properties
+ -pre-compile: called before javac compilation
+ -post-compile: called after javac compilation
+ -pre-compile-single: called before javac compilation of single file
+ -post-compile-single: called after javac compilation of single file
+ -pre-compile-test: called before javac compilation of JUnit tests
+ -post-compile-test: called after javac compilation of JUnit tests
+ -pre-compile-test-single: called before javac compilation of single JUnit test
+ -post-compile-test-single: called after javac compilation of single JUunit test
+ -pre-jar: called before JAR building
+ -post-jar: called after JAR building
+ -post-clean: called after cleaning build products
+
+ (Targets beginning with '-' are not intended to be called on their own.)
+
+ Example of inserting an obfuscator after compilation could look like this:
+
+ <target name="-post-compile">
+ <obfuscate>
+ <fileset dir="${build.classes.dir}"/>
+ </obfuscate>
+ </target>
+
+ For list of available properties check the imported
+ nbproject/build-impl.xml file.
+
+
+ Another way to customize the build is by overriding existing main targets.
+ The targets of interest are:
+
+ -init-macrodef-javac: defines macro for javac compilation
+ -init-macrodef-junit: defines macro for junit execution
+ -init-macrodef-debug: defines macro for class debugging
+ -init-macrodef-java: defines macro for class execution
+ -do-jar-with-manifest: JAR building (if you are using a manifest)
+ -do-jar-without-manifest: JAR building (if you are not using a manifest)
+ run: execution of project
+ -javadoc-build: Javadoc generation
+ test-report: JUnit report generation
+
+ An example of overriding the target for project execution could look like this:
+
+ <target name="run" depends="jdwpgen-impl.jar">
+ <exec dir="bin" executable="launcher.exe">
+ <arg file="${dist.jar}"/>
+ </exec>
+ </target>
+
+ Notice that the overridden target depends on the jar target and not only on
+ the compile target as the regular run target does. Again, for a list of available
+ properties which you can use, check the target you are overriding in the
+ nbproject/build-impl.xml file.
+
+ -->
