Problems with Ant build.xml configuration to work with external Libraries and Java property files

I have a problem with Ant Build Tool.
First, below you can see my project structure:
and the content of my build.xml file is:
<?xml version="1.0" encoding="UTF-8"?>
<project name="addonGenerator" default="main" basedir=".">
<property name="projectName" value="addonGenerator"/>
<property name="src.dir" location="src"/>
<property name="build.dir" location="bin"/>
<property name="dist.dir" location="dist"/>
<target name="compile" description="compile the source ">
<mkdir dir="${build.dir}"/>
<javac srcdir="${src.dir}" destdir="${build.dir}">
<classpath>
<pathelement path="lib/velocity-1.7.jar"/>
<pathelement path="lib/log4j-1.2.16.jar"/>
</classpath>
</javac>
</target>
<target name="dist" description="package, output to JAR">
<mkdir dir="${dist.dir}"/>
<jar jarfile="${dist.dir}/${projectName}.jar" basedir="${build.dir}">
<zipgroupfileset dir="lib" includes="velocity-1.7.jar" />
<zipgroupfileset dir="lib" includes="log4j-1.2.16.jar" />
<manifest>
<attribute name="${projectName}" value="main"/>
<attribute name="Main-Class" value="main.java.AddonGenerator"/>
</manifest>
</jar>
</target>
<target name="clean" description="clean up">
<delete dir="${build.dir}"/>
<delete dir="${dist.dir}"/>
</target>
<target name="main" depends="clean, compile, dist"/>
</project>
I don't know how setup the Ant build.xml to build and run my project with external libraries and the java property file generator.properties

To include your generator.properties file in the .jar file, add your resources directory when building the .jar:
<jar jarfile="${dist.dir}/${projectName}.jar" basedir="${build.dir}">
<fileset dir="src/main/java/resources"/>
Since you are currently building a “fat jar” (by directly including the contents of your library .jars in your application .jar), you can run by simply invoking your .jar file. Such a target obviously requires the .jar file to be built, so it makes sense to depend on the "dist" target:
<target name="run" depends="dist">
<java jar="${dist.dir}/${projectName}.jar"/>
</target>
On another note, I don’t think you want to pass src as your source directory, unless your classes actually declare themselves with ‘package main.java;’ (which they shouldn’t). You should pass the actual root of your packages to the javac task:
<property name="src.dir" location="src/main/java"/>
You should also make the "dist" target depend on "compile", since, well, it depends on having compiled classes available.
I also would suggest that your default target, "main", avoid calling the "clean" target. You should not clean before every single build; that defeats one of the most useful benefits of Ant, namely the ability to update only the things that need to be updated. You should only clean when you need to, with a command like ant clean compile or simply ant clean.
Note that once "dist" depends on "compile", and once "main" no longer calls "clean", you can simply remove the "main" target and change your project’s default target to "dist". When you think about it, this makes sense: the default action is to build and package the application.

Cannot build JavaFX application using Ant

Update on copying resources using JavaFX ant tasks
There is no folder with fxml, css and other files in my output jar file. If put it manually everything works, how to say ant to exlictly include folder ?
Based on the Java Deployment Tutorial JavaFX Ant Tasks HelloWorld build.xml sample, and modifying it to add a resources directory (which is a sibling to the project src, classes and dist directories). Place your fxml and css in the resources directory to get them included in the jar. The directory structure of the copied files will match the directory structure of the resources directory, so if you just put them in the resources directory with no sub-directories, the files will show up in the root of the jar file (so when you use the resources reference them relative to the root (e.g. FXMLLoader.load(getResource("/main.fxml"))). I made these modifications without testing as I don't use ant for builds anymore.

You likely have a runtime issue not a build issue
It would seem that the application builds fine and you are getting a runtime error trying to run your application, either due to an issue in your application code or because the resources required for execution are not present.
Try a simpler application which does not include any FXML and build and execute that - if that works than either your error was in your application code or in the code which copies the FXML resources to your build package.
On Intellij syntax highlighting of JavaFX Ant tasks
Regarding the "URI is not registered" error in Intellij, that is a bit of a red-herring. It just means that you haven't registered the schema for the fx namespace with Idea, so Idea cannot validate the document (and provide context sensitive code completion on XML tags). As long as you haven't made syntax or structure errors in your XML (which you probably haven't or ant would likely reject it), then you can ignore such error messages if you wish.
You can find more information on this here:
Intellij Idea Help - Referencing DTD or Schema
Note: I don't think Oracle provide a full XML schema for the JavaFX ant tasks, so it will probably not be possible for you to configure Idea to validate the JavaFX ant task elements of your ant build.xml file. However, that should not prevent you from building your application - your best policy is probably to configure Idea to ignore the JavaFX ant tasks XML schema, so it no longer displays annoying and misdirecting red highlights on your build.xml file.
Alternative Technology
You may (or may not) find using the JavaFX Maven plugin or JavaFX Gradle plugin a better solution for you than using the JavaFX Ant Tasks directly.

Using Ant's classpath in Eclipse

I have an Ant build.xml file that works just fine on the command line: it compiles, builds the JAR, and I am able to execute the main method from the JAR just fine. The build.xml file references several thirdparty libraries that are scattered here and there. When building the JAR, the script doesn't include all the thirdparty libraries into the JAR itself. Instead, it puts their path into the JAR's manifest. This helps to keep my JAR slim and tidy.
I'd like to be able to edit and debug my project in Eclipse, but I can't find an easy way to do so. I can have my project use the Ant file to build the project, and that seems to work. However, Eclipse is having trouble finding the thirdparty libaries, and thus Eclipse is having two problems:
it shows (in the text editor) lots of compile errors, because
lots of classes are undefined, and
it can't execute the JAR.
I can solve both of the above problems by specifying by hand, in two difference places (i.e., the build path via Properties->Java Build Path->Libraries, and the execution classpath via Run Configurations->Classpath), all the third party libraries. But it seems like I shouldn't have to do this manually, since all the third party libraries are already listed in my JAR's manifest. What am I doing wrong?
Here's my build.xml file:
<!-- Set global properties for this build -->
<property name="src" location="./src" />
<property name="build" location="./build"/>
<property name="dist" location="./dist"/>
<property name="logs" location="./logs"/>
<property name="docs" location="./docs"/>
<property name="jar" location="${dist}/dynamic_analyzer.jar"/>
<property name="lib" location="../../thirdparty/lib"/>
<property name="hive-util" location="../../hive-utils/dist"/>
<property name="hpdb" location="../../hive-db/hpdb/dist"/>
<property name="static" location="../../hive-backend/static_analyzer/dist"/>
<property name="mainclass" value="com.datawarellc.main.DynamicMain"/>
<path id="dep.runtime">
<fileset dir="${lib}" includes="**/*.jar"/>
<fileset dir="${hive-util}" includes="**/*.jar"/>
<fileset dir="${hpdb}" includes="**/*.jar"/>
<fileset dir="${static}" includes="**/*.jar"/>
</path>
<target name="clean">
<delete dir="${build}"/>
<delete dir="${dist}"/>
<delete dir="${docs}"/>
<delete dir="${logs}"/>
</target>
<target name="init">
<tstamp/>
<mkdir dir="${build}"/>
<mkdir dir="${dist}"/>
<mkdir dir="${logs}"/>
</target>
<target name="compile" depends="init">
<javac srcdir="${src}" destdir="${build}" debug="on" includeantruntime="false">
<classpath refid="dep.runtime" />
</javac>
<!-- Debug output of classpath -->
<property name="myclasspath" refid="dep.runtime"/>
<echo message="Classpath = ${myclasspath}"/>
</target>
<target name="jar" depends="compile">
<!-- Put the classpath in the manifest -->
<manifestclasspath property="manifest_cp" jarfile="${jar}" maxParentLevels="10">
<classpath refid="dep.runtime" />
</manifestclasspath>
<jar jarfile="${jar}" basedir="${build}">
<manifest>
<attribute name="Main-Class" value="${mainclass}"/>
<attribute name="Class-Path" value="${manifest_cp}"/>
</manifest>
<zipfileset dir="${src}" includes="**/*.xml" />
</jar>
</target>
You can see that I have third-party libraries in several directories (${lib}, ${hive-util}, ${hpdb}, and ${static}). I use these to create a path called dep.runtime. I then include dep.runtime in the manifest when building my jar. How can I get Eclipse to use the same dep.runtime for the build path and the classpath when executing?

An alternative to perl is to use an embedded groovy task:
<project name="demo" default="eclipse-files">
<property name="src.dir" location="src"/>
<property name="classes.dir" location="build/classes"/>
<path id="dep.runtime">
<fileset dir="${lib}" includes="**/*.jar"/>
<fileset dir="${hive-util}" includes="**/*.jar"/>
<fileset dir="${hpdb}" includes="**/*.jar"/>
<fileset dir="${static}" includes="**/*.jar"/>
</path>
<target name="bootstrap">
<mkdir dir="${user.home}/.ant/lib"/>
<get dest="${user.home}/.ant/lib/groovy-all.jar" src="http://search.maven.org/remotecontent?filepath=org/codehaus/groovy/groovy-all/2.1.4/groovy-all-2.1.4.jar"/>
</target>
<target name="eclipse-files">
<taskdef name="groovy" classname="org.codehaus.groovy.ant.Groovy"/>
<groovy>
import groovy.xml.MarkupBuilder
project.log "Creating .classpath"
new File(".classpath").withWriter { writer ->
def xml = new MarkupBuilder(writer)
xml.classpath() {
classpathentry(kind:"src", path:properties["src.dir"])
classpathentry(kind:"output", path:properties["classes.dir"])
classpathentry(kind:"con", path:"org.eclipse.jdt.launching.JRE_CONTAINER")
project.references."dep.runtime".each {
classpathentry(kind:"lib", path:it)
}
}
}
</groovy>
</target>
<target name="clean">
<delete file=".classpath"/>
</target>
</project>
Notes:
The bootstrap target will download the 3rd party groovy jar (No dependency on perl)
Groovy can access the "dep.runtime" ANT path directly and iterate over its contents
Groovy has excellent support for writing XML files.
The following answer is similar and additionally generates the Eclipse .project file.
Using Apache Ivy with netbeans

I came up with the following workaround, inspired by the link provided by #leeand00.
First, I wrote a simple Perl script (called genClasspath.pl) that generates the .classpath file that Eclipse uses.
#!/usr/bin/perl
use strict;
if (#ARGV != 2) {
print STDERR "Usage: $0 OUTFILE CLASSPATHSTRING\n";
print STDERR "e.g., $0 .classpath path1:path2:path3\n";
exit 1;
}
my $OUTFILE = $ARGV[0];
my $CLASSPATHSTRING = $ARGV[1];
open my $out_fh, '>', $OUTFILE or die "Couldn't open output file: $!";
print $out_fh q{<?xml version="1.0" encoding="UTF-8"?>
<classpath>
<classpathentry kind="src" path="src"/>
<classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER"/>
<classpathentry kind="output" path="build"/>
};
my #libs = split(":", $CLASSPATHSTRING);
foreach my $thisLib (#libs){
print $out_fh " <classpathentry kind=\"lib\" path=\"$thisLib\"/>\n";
}
print $out_fh "</classpath>\n";
Then, I have my build.xml file call this script with the content of dep.runtime:
<target name="compile" depends="init">
<javac srcdir="${src}" destdir="${build}" debug="on" includeantruntime="false">
<classpath refid="dep.runtime" />
</javac>
<property name="myclasspath" refid="dep.runtime"/>
<exec dir="." executable="../../scripts/genClasspath.pl" os="Linux">
<arg value=".classpath"/>
<arg value="${myclasspath}"/>
</exec>
</target>
The only catch is that I need to run Ant on the command line at least once before I open the project in Eclipse. But when I do, Eclipse is able to compile and execute my project just fine, since the classpath is exactly the same as Ant's.

Create jar for android project in eclipse

Hello all how can I create jar file of my project that is created in android using eclipse. I have done in this way project -> right-click->export --> select builder -->antbuilder-->ok then after this process build.xml will be created. On bulid.xml I will create new builder.
Right click on project -> properties --> select new -->give build.xml and your project path and press ok, new builder will be created.
Now select that builder from project properties and press ok.
Now build your project and your jar will be created in bin folder.
I have followed above process but my jar is not found in bin folder. I can see my build.xml is created and all process goes smooth but still jar is not created. Can any one tell me how can I do this?
My build.xml
<?xml version="1.0" encoding="UTF-8" standalone="no"?>

In Eclipse, select project, right click on the project, Select Export, From that select Jar. Then follow the simple wizard and give the destination where you want to save your jar, and finish. You can find your jar there.

Step 1. Create Android library project as explained here.
Step 2. Now you need to give reference of Android Library project created in step 1 to your client application. There are two ways to do so.
•Give reference of Android Library Project itself by client app
property -> Select 'Android' on left pane -> In Libraty Section, Add
Android Libraty project (This is explained at link given in Step 1
above)
•Give the reference of .jar file of Android Library project
(from Location of Android Library project -> bin -> .jar file).
Client Application -> Properties -> Click 'Java Build Path' in lefe
pane -> Go to 'Libraries' Tab -> Click 'Add External JARs' button and
select the .jar file -> Go to 'Order and Export' tab and select the
added .jar file reference and move it to top.
Hope this will help you

How do you transition from using Eclipse for your builds to using Ant

I have a spring web application in Eclipse Helios. I use Ant for my builds on other projects but am not familiar with initially setting up Ant build files. Is there a painless way to make the transition from using Eclipse to do my builds, to creating an Ant build file and any supporting files? I tried copying a basic Ant build file into my application but I'm not sure if it's even close to what I need. I've included it below. It's giving me this error when I run it.
