When I do "make clean" it deletes all the object files , in C distributions.
What would be the command "make clean" when using ant, in Java distributions?
Java based build tools generaly build everything in target directory. ANT builds typically have a "clean" target that works as follows:
<target name="clean" description="Cleanup build files">
<delete dir="${build.dir}"/>
</target>
My advice is not to fight this one :-) It might look dumb but it's how more advanced tools like Maven work by default.
Example
I would typically declare some standard properties at the top of my build file:
<property name="src.dir" location="src/main/java"/>
<property name="build.dir" location="build"/>
<property name="dist.dir" location="${build.dir}/dist"/>
<property name="jar.main.class" value="org.demo.App"/>
<property name="jar.file" value="${dist.dir}/${ant.project.name}.jar"/>
Which are used to build my jar as follows:
<target name="compile" description="Compile code">
<mkdir dir="${build.dir}/classes"/>
<javac srcdir="${src.dir}" destdir="${build.dir}/classes" includeantruntime="false" debug="true" classpathref="compile.path"/>
</target>
<target name="build" depends="compile" description="Create executable jar archive">
<jar destfile="${jar.file}" basedir="${build.dir}/classes">
<manifest>
<attribute name="Main-Class" value="${jar.main.class}" />
</manifest>
</jar>
</target>
If you look carefully you'll notice everything ANT does is created under the "build" subdirectory.

I'm trying to use jenkins to run selenium webdriver test (continuous integration) but so far I've had no success at all. My setup:
- eclipse
- testng
- ant (build.xml files)
- jenkins
- everything is hosted locally
I'm running my test in parallel (1 test, 3 browsers) and this works fine if I run the testng file, if I run the ant file (build.xml) it says 'build successful' but nothing happens if also run this same file in jenkins it says the same thing 'build successful' but again nothing happens. From this I can deduce that jenkins is running the correct file but its just not executing the test. I've even tried to use maven but I don't understand it so the code doesn't even compile when I take this route.
Can someone help me and point me in the right direction because I believe I'm missing something. I've included a photo of my jenkins set and below is a copy of my ant file:

I can explain you the way I have done it in jenkins, maven and code. It should be pretty much similar with ant. This should certainly make jenkins fire your tests.
In code:
Create test suite class like below
#RunWith(Suite.class)
#Suite.SuiteClasses
({
Test1.class,
Test2.class
})
public class UnitTestSuite{}
In maven: use maven-surefire-plugin in pom.xml as below:
<!-- TEST -->
<plugin>
<!-- Runs the unit tests. -->
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>${surefire.version}</version>
<configuration>
<includes>
<include>**/UnitTestSuite.java</include>
</includes>
</configuration>
</plugin>
and finally in jenkins build section set goals as
clean install -e -Dmaven.test.failure.ignore=false
Try modifying your ant file by adding in target "jenkins_run_selenium" as below:
<target name="jenkins_run_selenium">
<mkdir dir="${junit.output.dir}"/>
<junit fork="yes" printsummary="withOutAndErr">
<formatter type="xml"/>
<test name="tests.MyUnitTests" todir="${junit.output.dir}"/>
<classpath refid="jenkins_run_selenium.classpath"/>
</junit>
</target>

Suggested Solution
If you want to use ant with JavaFX, you should use Oracle's JavaFX ant tasks.
The JavaFX runtime is included with Java 7 and the Oracle JavaFX ant tasks are aware of it's location, so when you use the Oracle ant tasks, builds of projects referencing JavaFX work.
Why your current build fails
Compilation fails for your script because the JavaFX runtime (jfxrt.jar) is not on the default class path for Java 7.
For Java 8 the JavaFX runtime is on the class path.
You can still use plain ant without the Oracle JavaFX ant tasks to build your application (just by ensuring jfxrt.jar is on the class path for your build step), however use of the Oracle tasks is recommended as they will also appropriately package your application for distribution.

My company only uses Ant to build projects. However, Jenkins only suggests Maven as a build tool for plugin development.
How could I package my Jenkins plugin to a .hpi file using Ant and avoiding Maven at all costs?
Here is a way to build a Jenkins plugin using Ant. Let's make a script that builds a plugin skeleton which name is "awesome".
Default plugin arborescence
awesome-plugin/
-- awesome/
-- src/
-- pom.xml
Instructions
Add a lib/ folder which contains the following jars:
to be found in your Jenkins home directory Jenkins\war\WEB-INF\lib (note: you have to use the exact same versions that your current Jenkins use):
access-modifier-annotation-1.4.jar
bridge-method-annotation-1.4.jar
commons-io-1.4.jar
guava-11.0.1.jar
jenkins-core-1.513.jar
json-lib-2.4-jenkins-1.jar
remoting-2.23.jar
sezpoz-1.9.jar
stapler-1.207.jar
to be found on the web (you can choose the last version released):
servlet-api-2.4.jar
Replace the existing pom.xml with the following build.xml.
In the Ant script, you should adapt:
the project name, awesome here,
the plugin version,
the Jenkins version this plugin is made for,
the project group.id (main package), org.jenkinsci.plugins.awesome here.
New plugin arborescence
awesome-plugin/
-- awesome/
-- src/
-- lib/
-- you should have 10 jars here
-- build.xml

To launch the build, cd towards the build.xml and type ant.
I know you stated "at all costs", but a compromise might be less effort, and still give super fast builds. A big reason for me to try to avoid maven is that the compile time is sloooowwwwww. That said, maven is quite good at creating the hpl file, and handling dependencies. The following targets are quite useful for helping to set up a super-fast non-maven build:
use 'mvn hpi:hpl' to generate the hpl file
use 'mvn dependency:copy-dependencies' to download all your dependencies, and put them into target/dependency, where it's easy to reference them from your ant script (you can add a symbolic link if necessary, from lib to target/dependency)
I have a a jar right now that uses external dependencies. I'm trying to create a jar that packages all the external dependencies inside, and will just give me one jar. I saw this question asked multiple times, but I still can't figure it out. I'm using Ant, and copied some of the examples I saw on here. I'm using zipgroupfileset to reference the external(now internal) jars. As soon as I added the zipgroupfileset I got a runtime error that said my Runner class could not be found.

To make things simpler:
Create a separate sources jar for compilation. Then, have a separate compiled jar without the sources.
Don't include the third party jars. Instead, use Ivy with Ant. Ant will automatically download the required jars. In fact, I've see sources that just include the ivy.jar, so Ivy will automatically be configured when you unjar the sources. You type in ant, and everything just builds.
As an alternative, you can look at Maven which is how many projects are now packaged. In fact, if your jar is an open source project, you can probably host it on the OSS Maven repository. This way, no one even needs to manually download your compiled jar. If they want it, they configure their Maven project to do it for them.
i think the problem is that you use basedir="bin" in the your jar task. then path of your zipgroupfileset convert to bin/${external-lib-dir}
I have a Eclipse-Java-Project with an ANT-build-file. This build file exports a jar of the project without compiling it. So I only export the sources.
<target name="jar">
<mkdir dir="/jar"/>
<jar destfile="/jar/my_test_jarfile.jar" basedir="/src" />
</target>
I use this generated jar in another eclipse java project and set the path to the jar in the build-path-settings of the project. The problem is that eclipse says it cannot resolve the namespace of the imported classes of the jar.
If I export the jar manually by right clicking on the project and then "Export" and putting the jar to the build path of the other project, everything works fine and there are no errors. So the question is now, what am I doing wrong?
So here is my solution. It seems that you have to compile the source first and then pack it into a jar. I don't give a guarantee that this jar is exactly the same like the one you get from eclipse when you do the right click thing and export etc.
But it works for me, there are no namespace errors any longer. so here is a minimum version of my ant targets:
<project default="run" basedir=".">
<property name="src.dir" value="src" />
<property name="classes.dir" value="bin" />
<property name="build.dir" value="build" />
<path id="libs">

<include name="*.jar"/>
</fileset>
<pathelement path="${basedir}\${classes.dir}"/>
</path>

<antcall target="jar"/>
</target>
<target name="compile">
<javac debug="true" srcdir="${src.dir}" destdir="${classes.dir}" classpathref="libs" encoding="UTF-8" />

<target name="jar">
<jar destfile="${build.dir}/my_jar_file.jar" basedir="${classes.dir}">
