          I had the same problem when I built jacoco.exe with Maven plugin version 0.7.5 however Jankins JaCoCo plugin version was 1.0.x. The versions 1.0.x should use Maven plugin version 0.7.4 or lower.

          After my admin did upgrade of Jenkins plugin to version 2.0.0 the problem disappeared with Maven plugin version 0.7.5.<timestamp>. Although the graph is displayed I found another issue JENKINS-32528.

          Log:
          Report 100% for empty Coverage objects

          If a section of code has no branches, we should report 100% branch coverage
          not 0% coverage. This prevents spurious threshold violations for such code.

          (This concern also applies to other coverage measures, although in practice
          I've only encountered this problem for branches.)

          Fixes JENKINS-25076 and JENKINS-29117

          We now report 100% for such branches via https://github.com/jenkinsci/jacoco-plugin/pull/79, this will be included in the next release.
