probably this is a very basic question but I am new to java, so please bear with me.
I am trying to run java task in ant and I want to know if there is any way to get all the name of the classes inside a folder in ant?
This is the build.xml file
<project default='run-test' basedir=".">
<property name="src" value="src"/>
<property name="test" value="test"/>
<property name="build" value="build"/>
<property name="build-classes" value="build/classes"/>
<property name="build-test-classes" value="build/test/classes"/>
<property name="junit4" value="/usr/share/java/junit4.jar"/>
<target name="init">
<mkdir dir="${build-classes}"/>
<mkdir dir="${build-test-classes}"/>
</target>
<target name="compile" depends="init">
<javac includeantruntime="false"
srcdir="${src}"
destdir="${build-classes}"/>
</target>
<target name="compile-test" depends="compile">
<javac includeantruntime="false"
classpath="${junit4}:${build-classes}"
srcdir="${test}"
destdir="${build-test-classes}"/>
</target>
<target name="run-test" depends="compile-test">
<java classpath="${junit4}:${build-classes}:${build-test-classes}"
classname="org.junit.runner.JUnitCore"
args="myclass.MyClassTest"/> <---This is my problem
</target>
<target name="clean">
<delete dir="${build}"/>
</target>
</project>
I have to manually mention the name of the class in the arguments.
Is there any way where I can only mention the folder and all the class names will be taken up as arguments for the javatask automatically?
Ant ships with a task for running JUnit tests.
In the run-test target in your example, replace the <java> task with the following:
<junit>
<formatter type="plain" usefile="false"/>
<classpath>
<pathelement location="${junit4}"/>
<pathelement location="${build-classes}"/>
<pathelement location="${build-test-classes}"/>
</classpath>
<batchtest>
<fileset dir="${build-test-classes}">
<include name="**/*.class"/>
</fileset>
</batchtest>
</junit>

I am pretty new to Ant but, I have a general understanding. I just cannot get this to work.

This gives me my classes folder with movie as the next folder and then in there, I have my 3 classes. However, it keeps saying class not found and I have no idea what I am doing wrong.
Figured it out. I am an airhead sometimes.

I am trying to set up unit testing with Travis-CI for my java project, and I am having some difficulties. The issue is that I would like it to run all of the unit tests I have in the src/test/ file without having to specify the test name directly. This is because I will keep adding tests, and I would not like to constantly export the build.xml file. The xml I currently have is:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!-- WARNING: Eclipse auto-generated file.

If anyone could help me out it would be much appreciated.
Thanks!
I am new to ANT and to use it, I simply created a new java project in Eclipse that just print the word Welcome in the screen. I ran the program using Eclipse and "Welcome" was successfully printed on the screen. This is my program
public class welcome {
public static void main(String[] args)
{
System.out.println("Welcome!!!");
}
}
Then I just followed the usual way to build ANT file using Eclipse so I used Export feature and choose ANT buildfile.
This the buildfile I have got:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!-- WARNING: Eclipse auto-generated file.

when I ran the program as Ant, it only gives me a message that build successful! without printing the "Welcome" word on screen!
This is the output

The default target of your ant file is "build" which will create a jar file of your project (which can be then executed later). If you want to run your project via ant, change the target to "welcome" (see the end of your ant file). That should execute the program as you expected.
Apache Ant is a Java library and command-line tool whose mission is to
drive processes described in build files as targets and extension
points dependent upon each other. The main known usage of Ant is the
build of Java applications
Also class names first letter should be CAPITALIZED ...
More or less this is how your ant should look like, but i still dont understand why you want to use ANT for whatever you are trying to do here.

On my Linux box test runs fine and everything looks good. But on my Windows, Ant gives my nice:
java.lang.NoClassDefFoundError: junit/framework/TestListener
Ant in debug mode however told me that he loaded TestListener.class from suplied junit-4.10.jar file.
Try this answer http://youtrack.jetbrains.com/issue/TW-4882:
To fix the problem you should either use fork="true" attribute for
junit task (in this case classpath will be created correctly), or
to copy junit.jar to ANT_HOME/lib (to ensure correct class loading).
Here is also bug for this https://bugs.eclipse.org/bugs/show_bug.cgi?id=36198. Last comment says JUnit is available in Ant via the org.eclipse.ant.optional.junit fragment
Hey guys I've been trying all day to get an ant file to automatically build my project. The file (appended below) was on a web page I found and is pretty thorough.
My problem is that it works as long as I don't run the "clean" target. Once the I run the "clean" target the "test" target ceases to work. I get NoClassFound errors on all test classes. Even though it worked earlier.
I'm working on a Macbook (10.5.8) using the latest version of eclipse. This error occurs running the file from eclipse and from a terminal using Ant version 1.7.1
I modified the file slightly to adapt it to my file structure which is as follows:
src/
packageA.packageB/
ClassA.java
...
ClassN.java
unittests/
packageA.packageB/
AllClassTests.java
ClassATest.java
...
ClassNTest.java
lib/
junit-4.7.jar
The ant file is:
<project name="SampleJUnitTests" default="dist" basedir=".">
<description>

I give up and hope that someone can shine a light on my problem.
Thanks a lot!
You haven't got any Ant target which builds the test classes. You could do this as part of the compile target if you wanted:
<target name="compile" depends="init" description="compile the source code " >
<javac srcdir="${src}" destdir="${build}">
<classpath>
<fileset dir="lib">
<include name="**/*.jar"/>
</fileset>
</classpath>
</javac>
<javac srcdir="${tests}" destdir="${build}">
<classpath>
<pathelement path="${build}"/>
<fileset dir="lib">
<include name="**/*.jar"/>
</fileset>
</classpath>
</javac>
</target>
