<!-- You may freely edit this file. See commented blocks below for -->

<!-- (If you delete it and reopen the project it will be recreated.) -->
<!-- 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 -->

<!--
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="${build.classes.dir}"/>
</obfuscate>
</target>
For list of available properties check the imported
nbproject/build-impl.xml file.
Another way to customize the build is by overriding existing main targets.
The targets of interest are:
-init-macrodef-javac: defines macro for javac compilation
-init-macrodef-junit: defines macro for junit execution
-init-macrodef-debug: defines macro for class debugging
-init-macrodef-java: defines macro for class execution
-do-jar: JAR building
run: execution of project
-javadoc-build: Javadoc generation
test-report: JUnit report generation
An example of overriding the target for project execution could look like this:
<target name="run" depends="CommandTerminal-impl.jar">
<exec dir="bin" executable="launcher.exe">
<arg file="${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.
