java - ANT build fails and gives classNotFoundExceeption in html report -

after doing many trial , errors on "how ant tag works ?", decided write own custom build xml file testcases written in java , integrated junit. unfortunately build script failing "classnotfoundexception". , can see log in generated html file see after running ant build script.

please see below

and guessed ant build pick source files (.java) , class files based in build folder , started running them, see "classnotfoundexception" in html report. please see below log :

class : "getlieninfo"

>   java.lang.classnotfoundexception: getlieninfo @ java.net.urlclassloader$1.run(urlclassloader.java:366) @ java.net.urlclassloader$1.run(urlclassloader.java:355) @ java.security.accesscontroller.doprivileged(native method) @ java.net.urlclassloader.findclass(urlclassloader.java:354) @ java.lang.classloader.loadclass(classloader.java:423) @ sun.misc.launcher$appclassloader.loadclass(launcher.java:308) @ java.lang.classloader.loadclass(classloader.java:356) @ java.lang.class.forname0(native method) @ java.lang.class.forname(class.java:186) 

after while changed .java .class in "include" tag of target called "run-tests" . reason doing is, thought ant not able ".java" files in source folder (src/test/services) hence changed ".class" , modified dir attribute value in "fileset" tag "build" may ".class" in build folder have compiled files stored. none of trial , error succeeded , ended same "classnotfoundexception".

i not sure went wrong , can me, please?

ok guys, ever little got you. found problem.

i had change include tag attribute name "name=/test/services/**/*.java"/>" , modify dir attribute in fileset tag "${src}" ; see below :

<batchtest fork="yes" todir="${reports}/raw/">        <formatter type="xml"/>          <fileset dir="${src}" >              <exclude name="myfile.java"/>                 <include name="/test/services/**/*.java"/>  //<----this had modify. 

note: under src directory have test/services folder has source ".java" files in it.

        </fileset> </batchtest> 

it solved problem, don't understand why ant build not able identify source files when gave dir attribute dir="${src}/test/services" in fileset tag , kept name attribute in include tag name="**/*.java" . understanding fileset tag should build path for given dir path , once path build include tag include or mentioned source files i.e. ".java" .
