Using examples that come with Tomcat as following:
java -version
openjdk version "11.0.1" 2018-10-16
OpenJDK Runtime Environment 18.9 (build 11.0.1+13)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.1+13, mixed mode)
mkdir /tmp/j
cd /tmp/j
wget
"http://repo1.maven.org/maven2/org/jacoco/jacoco/0.8.3/jacoco-0.8.3.zip";
aunpack jacoco-0.8.3.zip
wget
"https://archive.apache.org/dist/tomcat/tomcat-8/v8.5.29/bin/apache-tomcat-8.5.29.tar.gz";
aunpack apache-tomcat-8.5.29.tar.gz
cat <<END >./apache-tomcat-8.5.29/bin/setenv.sh
CATALINA_OPTS="\${CATALINA_OPTS}
-javaagent:/tmp/j/jacoco-0.8.3/lib/jacocoagent.jar=destfile=/tmp/j/jacoco.exec"
END
./apache-tomcat-8.5.29/bin/catalina.sh start
curl http://localhost:8080/examples/servlets/servlet/HelloWorldExample
./apache-tomcat-8.5.29/bin/catalina.sh stop 60
I just got non zero file:
ls -l jacoco.exec
-rw-r----- 1 evgeny.mandrikov wheel 38463 Mar 7 20:53 jacoco.exec
That includes information about execution of HelloWorldExample :
java -jar jacoco-0.8.3/lib/jacococli.jar execinfo jacoco.exec | grep
HelloWorldExample
f4baf7db7add6fb6 19 of 19 HelloWorldExample
Among many other class files:
java -jar jacoco-0.8.3/lib/jacococli.jar execinfo jacoco.exec | wc -l
703
And got following report:
java -jar jacoco-0.8.3/lib/jacococli.jar report jacoco.exec --classfiles
apache-tomcat-8.5.29/webapps/examples/WEB-INF/classes/ --html report
