Ant fails to find junit for project generated with wsdl2java - ant

Question

I created a axis2 soap client project with unit tests using the following command:
wsdl2java -t -uri http://myDomain.tld/myService.svc?wsdl
I then ran ant and got build errors because it could not find junit methods such as fail(),assertNotNull(), etc. I realize I need the compiler to reference a junit jar. Looking in the build.xml I see the following:
<property name="classes" value="${build}/classes"/>
<property name="lib" value="${build}/lib"/>
So I place junit-4.8.2.jar in the build.lib subfolder. I still get the same errors. What else do I need to do to get ant to build my project?
Update:
I made the following changes to the build.xml:
Added the lib folder as a path with the id local.class.path
<path id="local.class.path">
<fileset dir="${lib}">
<include name="*.jar"/>
</fileset>
</path>
Then I modified my init task to look for junit:
<available classpathref="local.class.path" property="junit.available" classname="junit.framework.TestCase"/>
<condition property="jars.ok">
<and>
<isset property="stax.available"/>
<isset property="axis2.available"/>
<isset property="junit.available"/>
</and>
</condition>
<!--Print out the availabilities-->
<echo message="Stax Availability= ${stax.available}"/>
<echo message="Axis2 Availability= ${axis2.available}"/>
<echo message="JUnit Availability= ${junit.available}"/>
And strangely the output is:
H:\Code\Java\test.axis2> ant pre.compile.test
Buildfile: H:\Code\Java\RiskTools.axis2\build.xml
init:
[mkdir] Created dir: H:\Code\Java\test.axis2\build
[mkdir] Created dir: H:\Code\Java\test.axis2\build\classes
[mkdir] Created dir: H:\Code\Java\test.axis2\build\lib
pre.compile.test:
[echo] Stax Availability= true
[echo] Axis2 Availability= true
[echo] JUnit Availability= ${junit.available}
BUILD SUCCESSFUL
Total time: 0 seconds
So it seems I am doing something wrong due to the line [echo] JUnit Availability= ${junit.available}

Answer 1

Apparently build/lib is the transient folder that gets blown away by ant clean. I made a folder called lib at the project root and then did the following to the build.xml.
In the root I added <property name="dep_libs" value="${project.base.dir}/lib"/>
I then change my path statement above to:
<path id="local.class.path">
<fileset dir="${dep_libs}">
<include name="*.jar"/>
</fileset>
</path>
Then everything worked.
