Problem with Ant using JUnit

[Unnsse Khan]

Hello there,

I usually just run my JUnit 3.8.1 unit tests straight from Eclipse.

Figured that it would be a good practice to run my unit tests from Ant (that way other developers wouldn't have to depend on Eclipse)...

Here's what I did so far:

<target name="run_tests">
        <junit printsummary="yes" haltonfailure="yes">
       <classpath>
            <pathelement location="${build.tests}"/>
        <pathelement path="${java.class.path}"/>
       </classpath>

       <formatter type="plain"/>

        <test name="my.test.TestCase" haltonfailure="no" outfile="result">
     <formatter type="xml"/>
</test>

  <batchtest fork="yes" todir="${reports.tests}">
          <fileset dir="${src.tests}">
                 <include name="**/*Test*.java"/>
         <exclude name="**/AllTests.java"/>
          </fileset>
  </batchtest>
      </junit>
</target>

Now, when I tried to run this target, this is the error I got back:

BUILD FAILED
Ant could not find the task or a class this task relies upon.
 
This is common and has a number of causes; the usual 
solutions are to read the manual pages then download and
install needed JAR files, or fix the build file: 
 - You have misspelt 'junit'.
   Fix: check your spelling.
 - The task needs an external JAR file to execute
     and this is not found at the right place in the classpath.
   Fix: check the documentation for dependencies.
   Fix: declare the task.
 - The task is an Ant optional task and the JAR file and/or libraries
     implementing the functionality were not found at the time you
     yourself built your installation of Ant from the Ant sources.
   Fix: Look in the ANT_HOME/lib for the 'ant-' JAR corresponding to the
     task and make sure it contains more than merely a META-INF/MANIFEST.MF.
     If all it contains is the manifest, then rebuild Ant with the needed
     libraries present in ${ant.home}/lib/optional/ , or alternatively,
     download a pre-built release version from apache.org
 - The build file was written for a later version of Ant
   Fix: upgrade to at least the latest release version of Ant
 - The task is not an Ant core or optional task 
     and needs to be declared using <taskdef>.
 - You are attempting to use a task defined using 
    <presetdef> or <macrodef> but have spelt wrong or not 
   defined it at the point of use
 
Remember that for JAR files to be visible to Ant tasks implemented
in ANT_HOME/lib, the files must be in the same directory or on the
classpath
 
Please neither file bug reports on this problem, nor email the
Ant mailing lists, until all of these causes have been explored,
as this is not an Ant bug.

What could I be possibly be doing wrong?

You did not tell us your Ant version, but if its 1.6.x,
you can drop your junit jar in ant/lib folder, or add it to Ant's classpath.

In Ant 1.7 you can add junit.jar to the task's classpath.

Dear Jan,

The version of Ant I use is the 1.6.5, which comes bundled with Eclipse 3.2

When I checked out Preferences -> Ant -> Runtime, there was a ant-junit.jar file inside the library...

Obviously, this is not the same as junit.jar?

Thanks for the response!

Kindest regards,

[Jan Cumps]

ant-junit is the integration library that holds the classes used to integrate junit in ant.

But you still need junit.jar. It's documented on the JUnit task's library dependencies.
