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