  <p>the strange thing is that, if i set the reportPath and itReportPath the same, no matter merged_unit.exec or merged_it.exec, the sonar analysis goes well
  but if i set what it should be , the error comes up .</p>
  
  <p>the project is a muti-modules one, so i use the xml below to merge (i only put one module first for testing)</p>
  
  <pre><code>&lt;target name="merge_unit_exec"&gt;
                  &lt;jacoco:merge destfile="/home/qatest/test-script/aaa/unittest/report/merged_unit.exec"&gt;
                          &lt;fileset dir="/home/qatest/jenkins/workspace/aaaa/aaa/target" includes="*.exec" /&gt;
                  &lt;/jacoco:merge&gt;
  &lt;/target&gt;
  </code></pre>
