This is ant script to generate jar file.problem is those code will generate jar but when i click on that jar it is not opening means it not showing any GUI.
im new to this please let me know what is going wrong.
javaGUI is project and Swing is class name
jar file will not open in GUI. You need to run jar file from console.
Go to dist directory -> run this command:
$ java -jar final.jar [optional parameters]
For more details : see this reference
UPDATE
Instead of giving ant from target execute, try this :
<target name="jar">
<mkdir dir="build/jar"/>
<jar destfile="build/jar/HelloWorld.jar" basedir="build/classes">
<manifest>
<attribute name="Main-Class" value="Swing"/>
</manifest>
</jar>

<target name="run">
<java jar="build/jar/HelloWorld.jar" fork="true"/>

Below is a simplified versin of a build.xml for a Java project. It completes "build" correctly (creates the correct .class files) and prints out "Finishing build". It does not, however, print out "Starting jar". What am I not understanding? The target "jar" depends on "build", so it should be run next.
Running it with target release.

Update the release target as follows to note that release depends on build then jar. i.e. depends="build,jar"
i.e.
<target name="release" depends="build,jar" description="Entry point">
<echo message="release ..."/>

I am a selenium user trying to generate xslt reports using Ant, but when I run Ant in cmd it is showing me error of build.xml not exist while I have build.xml file in my project folder.
I am using eclispe juno on windows 7 and and kept the build.xml file under the project.
I have java JDK1.7 on my machine and I have already set the environment variables(Java and ant both) as per instructions given on apache.org
Ant version is apache-ant-1.9.1
I have imported all necessary jar files (selenium + maven +saxon + all required for xslt report through ant) in my project in eclipse.
When I am trying to run ant through cmd it is showing me this error:-

Thanks you all for your great help, I have resolved that error ..
It was related to the path of the jar files , I provided incorrect path to the jars.
This was line 70 : -
<javac debug="true" destdir="${test.dest}" srcdir="${test.src}"
target="1.7" classpath="${test.classpath}">
this is related to the path to the jars and in the top line of my file I did provided this path - D:\All jars , while all required jars was not in this folder, now I updated the jar folder and it is working fine now.
Below is the Ant script i am trying in GAE project but when i look into the war file i see two class for each java file.
Just a fyi, WAR file created i open in winrar but even when i extract it winrar keeps on asking me to either replace existing file message. Not sure how even same file name & extension is present in one folder. Also i checked the "dist" & "classes" folder i does not have duplicate file.

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 am trying to write a build.xml file for my project. When I run build.xml as an Ant project, I get the following error:

I have imported log4j in LogAlerter.Java. Here is my build.xml file:

Try adding a classpath ref to your javadoc task:
<javadoc packagenames="src"
sourcepath="${src.dir}"
destdir="${docs.dir}"
classpathref="build.classpath">
What the warning is telling you is that you've not provided the full classpath to the javadoc task. Try adding a similar classpath ref to that in your compile task and see where that leads.
Importing is fine but make sure it is available at run time for the JavaDoc tool. log4j.jar should be present in your build.classpath.
Make use of the classpathref inside the docs target like so:
<javadoc packagenames="src" sourcepath="${src.dir}" destdir="${docs.dir}" classpathref="build.classpath">
