I am trying to do the code coverage using Jacoco. I have written the Jacoco configuration in ANT script.Jacoco working fine without logs in code. But it is error out for loggers (apache log4j) added in my code.
I tried to exclude the logs by adding below code in my ant script as <jacoco:coverage destfile="${result.exec.file}" excludes="org.apache.log4j.*">
still it is giving me same error.
I am getting below exception:
15:35:16 [junit] Testcase: testUncoveredMethod took 0.009 sec
