Jacoco ant task - no jacoco.exec output
ant, jacoco, java
Solution
I found the cause. It is stupid but there was no logging to indicate the error:
batchtest fork="true" todir="target/test-reports"
The fork parameter was set to false in the batchtest. Setting it back to "true" produces the expected jacoco.exec.
Problem
I configured my Ant task as ``` <target name="test" depends="init"> <jacoco:coverage destfile="target/jacoco.exec"> <junit printsummary="yes" haltonfailure="yes" fork="yes" forkmode="once"> <classpath refid="my_project.path"/> <formatter type="plain"/> <formatter type="xml"/> <batchtest fork="false" todir="target/test-reports"> <fileset dir="test"> <include name="**/*Test.java"/> </fileset> </batchtest> </junit> </jacoco:coverage> </target> ``` Which produces the expected junit result. However, the `target/jacoco.exec` is never created. I do not have any error during the `ant test report` task execution. test: [jacoco:coverage] Enhancing junit with coverage ``` ...
