我无法定义为什么Emma不生成运行时coverage数据。
运行测试时我忘记了什么？根据这篇文章：How to change Ant script with EMMA code-coverage so it can find runtime coverage data?
我将检测到的类放在类路径的顶部
ant-emma.xml：

当您使用错误的命令生成报告时，会出现此错误。大多数在线教程都提倡使用错误的命令（可能是旧的），甚至当我使用以下命令生成报告时也遇到了此错误：
{JAVA_HOME} \ jre \ lib \ ext> java -cp emma.jar emma报告-r html -in coverage.em，{ALFRESCO_HOME} \ coverage.ecEMMA：处理输入文件...EMMA：60毫秒内读取并合并了1个文件EMMA：无事可做：在任何数据文件中都找不到运行时覆盖率数据命令的正确用法是（在命令中标记额外的“ -in”：

实际上，我错误地假设我做错了方法...
[经过几天的思考，浪费了一些时间来理解问题。我找到了解决方案：在VM中添加一个参数：（对不起，我丢失了参考。）

-最后，我只需要修改我的'emma-do-test'任务：
<target name="emma-do-test" depends="emma-instrumentation" >
<junit printsummary="withOutAndErr" haltonfailure="true" fork="true" >
<classpath>
<path refid="classpath.emma.run" />
</classpath>
<formatter type="plain" usefile="false" />
<batchtest todir="${emma.report.dir}" >
<fileset dir="${test.src.dir}" includes="**/*Test.java" />
</batchtest>
<jvmarg value="-XX:-UseSplitVerifier" />
<jvmarg value="-Demma.coverage.out.file=${emma.runtime.coverage.data.file}" />
<jvmarg value="-Demma.coverage.out.merge=false" />
</junit>
<echo message="Emma Test Result : ${emma.report.dir}" />
