I created the JUnitReport for ant task.
But those file are not include JavaDoc ;-)
So I create JUnit report include JavaDoc using JavaDoclet technology
(Sample1,Sample2(Solution)).
		
1st step: create the java source code.
    /**
     * Hello world test message
     */
    @Test
    public void testHello() {
        assertTrue(true);
    }
Next step: write build.xml the following text. (For JUnit)
  <path id="common.classpath">
    <pathelement path="C:\eclipse\plugins\org.hamcrest.core_1.3.0.v201303031735.jar" />
    <pathelement path="C:\eclipse\plugins\org.junit_4.12.0.v201504281640/junit.jar" />
    <pathelement path="C:\Program Files\Java\jdk1.8.0_77\lib\tools.jar" />
    <pathelement location="./classes" />
  </path>
  <target name="all">
    <mkdir dir="./target/" />
    <delete dir="./target/junit" />
    <mkdir dir="./target/junit" />
    <junit printsummary="yes" haltonfailure="no">
      <classpath refid="common.classpath" />
      <formatter type="xml" />
      <batchtest fork="yes" todir="./target/junit">
        <fileset dir="./src/test/java">
          <include name="**/*Test.java" />
        </fileset>
      </batchtest>
    </junit>
Last step: write build.xml the following text. (For output report)
    <delete dir="./target/ut5" />
    <mkdir dir="./target/ut5" />
    <javadoc destdir="./target/ut5"
      encoding="UTF-8" docencoding="UTF-8"
      additionalparam="-J-Dfile.encoding=UTF-8">
      <classpath refid="common.classpath" />
      <packageset dir="src/test/java">
          <include name="jp/**" />
      </packageset>
      <doclet name="jp.ruru.park.ando.ut5.UT5Doclet" path="lib/UT5DocLet.jar">
        <param name="-junit" value="./target/junit" />
      </doclet>
    </javadoc>
Or this. (For Column change)
    <delete dir="./target/ut5" />
    <mkdir dir="./target/ut5" />
    <javadoc destdir="./target/ut5"
      encoding="UTF-8" docencoding="UTF-8"
      additionalparam="-J-Dfile.encoding=UTF-8"
      charset="UTF-8">
      <classpath refid="common.classpath" />
      <packageset dir="src/test/java">
          <include name="jp/**" />
      </packageset>
      <doclet name="jp.ruru.park.ando.ut5.UT5Doclet" path="lib/UT5DocLet.jar">
        <param name="-junit" value="./target/junit" />
        <param name="-junittree" value="abdegh cf r i j tt s nqq l" />
      </doclet>
    </javadoc>
