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

|

<!--
|

|
||||
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.
