We are running build and junit test on different slave machines. The code coverage is gathered perfectly on slave machine, the jenkins jacoco plugin finds the exec file but at the time of publishing report it fails with following error:-

[JaCoCo plugin] Could not parse coverage results. Setting Build to failure.
Build step 'Record JaCoCo coverage report' changed build result to FAILURE
Finished: FAILURE

Note:- jacoco plugin copies the classes, source files and exec file on the master home directory at F:\Jenkins\install\jobs\RAC_Client1015\builds\42\jacoco location. But dont know the reason why it fails with above error. Also, the slave where this job runs does not have F:\ drive.
