Ant Junit testing puttering out - need the summary

I'm using ant to build my java program. It's compiling fine but when I go to run the unit test class it can't find Class Files. I've messed with my classpath a ton and this exception keeps coming up?

The jars in lib are as follows:

  • ant.jar

  • hamcrest.jar

  • hamcrest-core-1.3.jar

  • hamcrest-all-1.3.jar

  • hamcrest-core.jar

  • junit.jar

I get this from the console


What am I doing wrong?


You need to add junit.jar and hamcrest-all-X.X.jar to your classpath.

you also need hamcrest-core-1.3.jar (for jUnit 4.11) in your lib folder.


Please follow the steps:

  1. Right click on the project.
  2. Choose Build Path Then from its menu choose Add Libraries.
  3. Choose JUnit then click Next.
  4. Choose JUnit4 then Finish.


  1. Go to Preferences | Java | JUnit
  2. Click "Add Package" and add "org.hamcrest.*"


If UPDATE1 not works then,

You can download JUnit 4.7 and put junit-4.7.jar in your build path (instead of the older version). That can solve your issue
