I’m trying to following apache’s ANT tutorial:
http://ant.apache.org/manual/index.html
I’m currently at the JUnit portion, but I keep getting errors related to not being able to find the junit.framework package.
I believe I’ve followed the tutorial exactly as follows – Here are the details:

Is there something I’m missing that’s needed to be included that was (or wasn’t) mentioned in the tutorial?
EDIT: Based on Alex’s inquiries, I tested to see if I had ant’s junit jars in my shared directories (which I do):
$ ls /usr/share/ant/lib/ant-junit*.jar
/usr/share/ant/lib/ant-junit.jar /usr/share/ant/lib/ant-junit4.jar
I also tried to manually put ant-junit, ant-junit4.jar, and junit.jar into my project’s lib directory, with the following results (all errors) after running ant clean junit:
- junit.jar – /Users/jtyler/Projects/AntHelloWorld/build.xml:45: Reference application not found.
- ant-junit.jar: package junit.framework does not exist
- ant-junit.jar and ant.junit4.jar: package junit.framework does not exist
- ant-junit4.jar: package junit.framework does not exist
EDIT The whole error when only junit.jar is included in the lib folder and calling ant clean junit is:
$ ant clean junit

On top of including the junit.jar file within my lib dir, I added the following line to my build.xml file right above the junit task declaration:
which is a copy of the ‘application’ path id declaration within the ‘run’ task definition.
The application builds successfully, and I get the following output with ant junit (test failure is expected):
Comments the following questions would be greatly appreciated:
Is the fact I actually needed to include the junit.jar file in my lib folder something I should be concerned about? I would assume this is not necessary if ant’s tutorial explicitly states “Because Ant has a built-in JUnit 3.8.2 you could start directly using it.”
Is the fact I needed to define the ‘application’ path id outside of the run task definition a typo within the apache ant tutorial? Or are there other things I missed or should consider?
Thanks to all those that helped.
