Coverages always are 0.
Weisong Sun
I execute the following command on my mac terminal, then I can get the file "jacoco.exec". I use Ant to extract report, but the coverages are always 0.
java -javaagent:/Users/sunweisong/Desktop/jacocoagent.jar=includes=net.mooctest.*,output=file,destfile=jacoco.exec

The above is my "build.xml" file, whether I need to add the configuration as like the following?
<target name="test" depends="compile"><!-- Step 2: Wrap test execution with the JaCoCo coverage task --><jacoco:coverage destfile="${result.exec.file}"><java classname="org.jacoco.examples.parser.Main" fork="true"><classpath path="${result.classes.dir}"/><arg value="2 * 3 + 4"/><arg value="2 + 3 * 4"/><arg value="(2 + 3) * 4"/><arg value="2 * 2 * 2 * 2"/><arg value="1 + 2 + 3 + 4"/><arg value="2 * 3 + 2 * 5"/></java></jacoco:coverage></target>在 2019年7月4日星期四 UTC+8上午11:58:31，Marc R.

Hi,obviously your command line does not execute anything. There is no main class to be executed.As a general rule we recommend to first make your test setup run, and then add code coverage to it. It it does not run without code coverage it will neither run with JaCoCo ;)Regards,-marc
