java - Running ant build gives "package org.junit does not exist"

Question

When I use a Java IDE to build projects (e.g. NetBeans) that have JUnit tests, they compile fine, but when I try to use ant outside of the IDE to run the build script, I get the error "package org.junit does not exist".

Answer 1

You should add your junit.jar into the classpath definition in your ant file.

There are many way to do it, one example is:

<junit printsummary="yes" haltonfailure="yes">
    <classpath>
        <path refid="your.classpath.refid" />
        <fileset dir="${junit.dir}">
            <include name="**/junit.jar" />
        </fileset>
    </classpath>
    ...
</junit>

See Ant Manual for details on setting up your classpath.
