我能够获得检测类，但我找不到我的运行时覆盖率数据。我正在使用build.xml(ant). 谁能帮帮我...以下是我的 build.xml 文件...

<path id="classpath.test">
    <pathelement location="${dir.dest}/test.jar"/>
<fileset dir="C:\Program Files\Java\jre7\lib\ext">
    <include name="**/*.jar"/>
</fileset>  
</path>     

<path id="emma.lib">
<pathelement location="C:\Program Files\Java\jre7\lib\ext\emma-2.0.5312.jar" />    
<pathelement location="C:\Program Files\Java\jre7\lib\ext\emma_ant-2.0.5312.jar" /> 
</path>     
<taskdef resource="emma_ant.properties" classpathref="emma.lib" />          

<target name="compile" depends="init,prepare" >
<javac classpathref="classpath.test" debug="on"  srcdir="${src.dir}" destdir="${out.dir}" />

<emma enabled="${emma.enabled}" >
<instr instrpathref="run.classpath"  destdir="${out.instr.dir}"  metadatafile="${coverage.dir}/coverage.emma"  merge="true">
    <filter excludes="*Test*"/>
</instr>        
 </emma>
     </target>

     <target name="run" depends="jar">
<java classpathref="classpath.test" classname="MainArea" fork="true"/>
     </target> 

     <target name="junit" depends="run">
    <junit fork="true" haltonfailure="false" printsummary="yes" failureproperty="test.failed">

        <classpath refid="classpath.test"/>
         <classpath>
            <pathelement location="${basedir}/src" />    
             <pathelement location="${out.instr.dir}" />     
             <pathelement location="C:\Program Files\Java\jre7\lib\ext\junit-4.10.jar" />    
             <pathelement location="C:\Program Files\Java\jre7\lib\ext\emma-2.0.5312.jar" />    
             <pathelement location="C:\Program Files\Java\jre7\lib\ext\emma_ant-2.0.5312.jar" />
        </classpath> 
          <formatter type="brief" usefile="false"/>
          <formatter type="xml"/>
        <batchtest todir=".">
            <fileset dir="./workspace">
                <include name = "MainAreaTest.java"/>
            </fileset>
        </batchtest>
        <jvmarg value="-Demma.coverage.out.file=${coverage.dir}/coverage.emma"/>
        <jvmarg value="-Demma.coverage.out.merge=true"/>     

    </junit>

    </target>

   <target name="emma.report"  depends="junit">

   <emma enabled="${emma.enabled}" verbosity="verbose"> 
 <report sourcepath="./workspace" >
 <fileset dir="${coverage.dir}" >
             <include name="*.emma" />
  </fileset> 

 <txt outfile="${coverage.dir}/coverage.txt"/>
            <html outfile="${coverage.dir}/coverage.html"/> 
    <xml outfile="${coverage.dir}/coverage.xml"/>
      </report>
   </emma> 

  </target>
  </project>

我得到这样的输出......

编译：

[javac] Compiling 5 source files to C:\Users\.hudson\jobs\Code_Coverage\out

[instr] processing instrumentation path ...
[instr] instrumentation path processed in 78 ms
[instr] [7 class(es) instrumented, 0 resource(s) copied]
[instr] metadata merged into [C:\Users\.hudson\jobs\Code_Coverage\coverage\coverage.emma] {in 0 ms}

艾玛报告：

 [echo] emma

您还需要包含 .ec 文件来生成报告。

<emma enabled="${emma.enabled}" verbosity="verbose"> 
 <report sourcepath="./workspace" >
   <fileset dir="${coverage.dir}" >
     <include name="*.emma" />
     <include name="*.ec" />
   </fileset> 

   <txt outfile="${coverage.dir}/coverage.txt"/>
   <html outfile="${coverage.dir}/coverage.html"/> 
   <xml outfile="${coverage.dir}/coverage.xml"/>
 </report>
