Hello Everyone:
I am an Electrical Engineer but I need to ANTLR for my project, developing
an algorithm, I have discovered that it a wonderful tool!
I need ANTLR support in NetBeans to materialize this algorithm.
I followed the instructions given on this page (to the T) :
http://www.antlr.org/wiki/display/ANTLR3/Integration+with+Development+Environments#IntegrationwithDevelopmentEnvironments-InstallandAddSupporttoProject
by I am getting errors in the build.xml :
My build.xml looks like this:
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
<?xml version="1.0" encoding="UTF-8"?>
<!-- You may freely edit this file. See commented blocks below for -->
<!-- some examples of how to customize the build. -->
<!-- (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 -->
<!-- the Compile on Save feature is turned off for the project. -->
<!-- You can turn off the Compile on Save (or Deploy on Save) setting -->
<!-- in the project's Project Properties dialog box.-->
<project name="MyAntlrProject" default="default" basedir=".">
<description>Builds, tests, and runs the project
MyAntlrProject.</description>
<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="${build.classes.dir}"/>
</obfuscate>
</target>
For list of available properties check the imported
nbproject/build-impl.xml file.
Another way to customize the build is by overriding existing main
targets.
The targets of interest are:
-init-macrodef-javac: defines macro for javac compilation
-init-macrodef-junit: defines macro for junit execution
-init-macrodef-debug: defines macro for class debugging
-init-macrodef-java: defines macro for class execution
-do-jar-with-manifest: JAR building (if you are using a manifest)
-do-jar-without-manifest: JAR building (if you are not using a
manifest)
run: execution of project
-javadoc-build: Javadoc generation
test-report: JUnit report generation
An example of overriding the target for project execution could look
like this:
<target name="run" depends="MyAntlrProject-impl.jar">
<exec dir="bin" executable="launcher.exe">
<arg file="${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.

The errors that I am getting are:
Could not load definitions from resource net/sf/antcontrib/antlib.xml. It
could not be found.
init:
deps-clean:
C:\Users\Krishna
Praveen\Documents\NetBeansProjects\MyAntlrProject\build.xml:148: Problem:
failed to create task or type if
Cause: The name is undefined.
Action: Check the spelling.
Action: Check that any custom tasks/types have been declared.
Action: Check that any <presetdef>/<macrodef> declarations have taken place.
BUILD FAILED (total time: 0 seconds)
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
I also tried following what was given here:
http://wiki.netbeans.org/AntlrInNetBeansJavaApplication
I don't get any errors but the .java files not are created, it simply makes
a JAR file.
I really appreciate any help!!
Thank You.
Krishna!
