This is the xml build code I have written. I am referencing the RunningPower jars folder and I believe the correct folder is being referenced as i able am able to compile. My base directory also contains a .classpath and .project file but not sure if they are important.

BUILD FAILED
C:\Users\dt208672\Perforce\depot\ebill\Automation\Selenium_eBill\RunningPower\build.xml:37: Problem: failed to create task or type classpath
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.

The classpath is needed also when running the Jar file so that the JVM could find library classes. However, when using the jar attribute in the java task, "all classpath settings are ignored" (see https://ant.apache.org/manual/Tasks/java.html). The simplest way is to specify the main class and add the compiled Jar along with the library Jars located in the RunningPowerJars directory:
<target name="run" description="Run the jar file" depends="jar" >
<java classname="RunningPower" fork="true">
<classpath>
<pathelement location="build/jar/RunningPower.jar"/>
<fileset dir="${lib.dir}">
<include name="**/*.jar" />
</fileset>
</classpath>
</java>
</target>
An unrelated note is that you could use the properties defined in init throughout the buildfile. For example, in the jar target you can use ${classes.dir} instead of repeating build/class.
It still doesn't make sense why the build would fail if the classpath element is added inside the java task when using the jar attribute. Although it is ignored, it is weird that it is failing with the "failed to create task or type" error.

Consider that when you use the -jar parameter using the java.exe in command line the classpath parameter is ignored, that also happens with the java task in ant.
So, what you must do is to provide the libraries you need to have available to the process launching that ant and that will suffice.
Once said that... where should you add those libraries then ? if you're launching from eclipse, you may add them on Window->preferences under Ant->Runtime->Global Entries.
If you're using some C.I. server like jenkins you could add them on numerous ways, I cannot give a direct answer because there could be many.
There is also an alternative. You may declare the dependency on the .jar MANIFEST.MF and put it under /lib or whatever inside that jar.

include maven-ant build libs in eclipse java project

I am struggling with maven-ant build with eclipse.
I did work like below steps.
[GUI] new java project
add build.xml in project top folder
run ant file and SUCCEED!
trying to code, but somehow auto completion does not work.(guessing eclipse can not read maven-ant dependency.path)
So I tried.
add ~/.m2/repository in build path as a External class folder - does not work - It looks weird to me to include whole this folder. My current project, I need little libraries, but it has whole libraries that I uses in other projects.
add builders with build.xml like Want an eclipse java project to run ant build files automatically - does not work neither.
How can I add this maven-ant libraries properly? Thanks for sharing your experiences and answers XD

Thanks again b

For what you are trying to do, you need the filesetId and versionsId="dependency.versions" in your declaration of:
<artifact:dependencies filesetId="dependency.fileset" versionsId="dependency.versions"
Then add a copy task like so:
<copy todir="${lib.dir}">
<fileset refid="dependency.fileset" />
<mapper classpathref="maven-ant-tasks.classpath"
classname="org.apache.maven.artifact.ant.VersionMapper"
from="${dependency.versions}" to="flatten" />
</copy>
The to="flatten" will flaten your dependencies into a single folder, then you can include that folder on the classpath of eclipse project or wherever you need it.

Error while using Ant with Google App Engine on Java

I have a Google App Engine application written in Java that I'm trying to get set up to work with the Travis continuous integration server. As part of this process, I need to automate the build using ant (previously, I had just been using Eclipse).
In Google's documentation for App Engine, they have a complete ant buildfile for an App Engine project:

What's gone wrong? Is Google's build.xml file wrong? I've literally never used ant before now, and I'm still pretty much a newbie with using Java and App Engine for production-quality applications so I'm totally lost here...
If anyone's ever set up App Engine to work with ant before, I'd really be interested in knowing how you did it. An example of an app engine application with a working ant build would be nice...

Run a ant scripts for a project that depends on other project

I am new for apache ant. Now, I am trying to run a single ant for two project. Lets see below....
I have a project named 'Multiply'. In that project, I write a java class named 'Multiply' and a function named 'multiply' that multiply two input integer and return result.
And then I created another project named 'Multiply-Test'. In build path configuration, I add 'Multiply' project into it to test. And then I write a Test class named 'MultiplyTest' and a test case that test return value of multiply function of Multiply class of Multiply Project.
And then I write a ant script (build.xml) file for 'Multiply-Test' project. My xml file is....

But I test by another way. That, and then, I clean and build both project. And then run 'MultiplyTest' class by Right click on class -> Run As. -> JUnit Test. Oh, It is work really. And Junit result is true that i wish.
Now, I don't know how to do for work that test class from ant scripts. I need to solve, but I don't know.
Anybody help me. Thanks..!

This doesn't look right:
<javac srcdir="${src.dir}/com/dat/multiply" destdir="${build.dir}">
<classpath refid="junit.class.path" />
</javac>
The srcdir of <javac> shouldn't include the /com/dat/multiply part. The <javac> documentation explains:
Do not include part of your package structure in the srcdir attribute
Instead, it should be:
<javac srcdir="${src.dir}" destdir="${build.dir}">
<classpath refid="junit.class.path" />
</javac>

ANT build fails and gives classNotFoundExceeption in html report

After doing so many trial and errors on "How ANT tag works ?", I decided to write my own custom build xml file for the testcases that was written in Java and integrated with JUnit. Unfortunately my build script failing with "ClassNotFoundException". And i can see the log in generated HTML file that you get to see after running ant build script.

And I guessed ANT build will pick all the source files (.java) and then it will look for all the class files that are based in build folder and started running them, but then I see "classNotFoundException" in HTML report. please see below log :

After a while I changed .java to .class in "include" tag of my target called "run-tests" . The reason for doing this is, I thought ANT is not able to look ".java" files in source folder (src/Test/Services) hence I changed to ".class" and then modified dir attribute value in "fileset" tag to "build" so it may easily look for ".class" in BUILD folder where I will have compiled files stored. But none of my trial and error succeeded and ended up with same "classNotFoundException".
I am not sure what went wrong , can someone help me, please?

OK guys, Thanks for what ever little help I got from you. I found the problem.
I had to change include tag attribute name to "name=/Test/Services/**/*.java"/>" and modify dir attribute in fileset tag to "${src}" ; see below :
<batchtest fork="yes" todir="${reports}/raw/">
<formatter type="xml"/>
<fileset dir="${src}" >
<exclude name="MyFile.java"/>
<include name="/Test/Services/**/*.java"/> //<----this where i had to modify.
NOTE: Under src directory I have Test/Services folder which has source ".java" files in it.
</fileset>
</batchtest>
It solved my problem, but then i don't understand why ant build was not able to identify source files when i gave dir attribute as dir="${src}/Test/Services" that is in fileset tag
and kept name attribute in include tag as name="**/*.java" . My understanding is fileset tag should build the path for for the given dir path , once the path is build include tag will include or look for mentioned source files i.e. ".java" .
