There exist several targets which are by default empty and which can be
7+
used for execution of your tasks. These targets are usually executed
8+
before and after some main targets. Those of them relevant for JavaFX project are:
9+
10+
-pre-init: called before initialization of project properties
11+
-post-init: called after initialization of project properties
12+
-pre-compile: called before javac compilation
13+
-post-compile: called after javac compilation
14+
-pre-compile-test: called before javac compilation of JUnit tests
15+
-post-compile-test: called after javac compilation of JUnit tests
16+
-pre-jfx-jar: called before FX SDK specific <fx:jar> task
17+
-post-jfx-jar: called after FX SDK specific <fx:jar> task
18+
-pre-jfx-deploy: called before FX SDK specific <fx:deploy> task
19+
-post-jfx-deploy: called after FX SDK specific <fx:deploy> task
20+
-pre-jfx-native: called just after -pre-jfx-deploy if <fx:deploy> runs in native packaging mode
21+
-post-jfx-native: called just after -post-jfx-deploy if <fx:deploy> runs in native packaging mode
22+
-post-clean: called after cleaning build products
23+
24+
(Targets beginning with '-' are not intended to be called on their own.)
25+
26+
Example of inserting a HTML postprocessor after javaFX SDK deployment:
27+
28+
<target name="-post-jfx-deploy">
29+
<basename property="jfx.deployment.base" file="${jfx.deployment.jar}" suffix=".jar"/>
30+
<property name="jfx.deployment.html" location="${jfx.deployment.dir}${file.separator}${jfx.deployment.base}.html"/>
31+
<custompostprocess>
32+
<fileset dir="${jfx.deployment.html}"/>
33+
</custompostprocess>
34+
</target>
35+
36+
Example of calling an Ant task from JavaFX SDK. Note that access to JavaFX SDK Ant tasks must be
37+
initialized; to ensure this is done add the dependence on -check-jfx-sdk-version target:
38+
39+
<target name="-post-jfx-jar" depends="-check-jfx-sdk-version">
40+
<echo message="Calling jar task from JavaFX SDK"/>
41+
<fx:jar ...>
42+
...
43+
</fx:jar>
44+
</target>
45+
46+
For more details about JavaFX SDK Ant tasks go to
47+
http://docs.oracle.com/javafx/2/deployment/jfxpub-deployment.htm
48+
49+
For list of available properties check the files
50+
nbproject/build-impl.xml and nbproject/jfx-impl.xml.
