想使用 ant 实现 jacoco 的离线插桩并生成报告， ant instruments 插桩成功，就是在执行 ant dump 时，一直报错，如下：

Note: further occurrences of HTTP header parsing errors will be logged at DEBUG level.

求大神指点迷津！！拜谢~~~(我没有在 jvm 修改参数，想知道离线插桩的处理方法)

下面是我的 build.xml 的内容：

   <property name="src.dir" location="./src/main/java" />
<property name="result.dir" location="./target" />
<!--  classPath  -->
<property name="result.classes.dir" location="${result.dir}/classes" />

<property name="result.report.dir" location="${result.dir}/site/jacoco" />
<property name="result.exec.file" location="${result.dir}/jacoco.exec" />
  <!--Jacoco的安装路径-->
 <property name="jacocoantPath" value="/home/glzhu/jacoco/jacocoant.jar"/>

<!--  Step 1: Import JaCoCo Ant tasks  -->
<taskdef uri="antlib:org.jacoco.ant" resource="org/jacoco/ant/antlib.xml">

    </jacoco:instrument>
</target>
