Coverage decreased (-0.02%) to 99.612% when pulling cbb85a9 on Godin:simplify_configuration_of_maven-surefire-plugin into 35b8ba3 on amaembo:master.

Thanks. I don't remember why it didn't work for me for the first time. What about the coverage of shared files? Will it be taken from the first run, from the second run or from both runs?

[Godin]

@amaembo from both runs.

In case of appending you get

$ java -jar ./jacoco-0.8.5/lib/jacococli.jar execinfo target/jacoco.exec
[INFO] Loading exec file target/jacoco.exec.

In case of two files these two sessions are just in two different files and merged at a time of generation of report. And this is the same operation as "merge":

$ java -jar ./jacoco-0.8.5/lib/jacococli.jar merge target/jacoco_java8.exec target/jacoco_java9.exec --destfile target/jacoco.exec
[INFO] Loading execution data file /private/tmp/streamex/target/jacoco_java8.exec.
[INFO] Loading execution data file /private/tmp/streamex/target/jacoco_java9.exec.
[INFO] Writing execution data to /private/tmp/streamex/target/jacoco.exec.

$ java -jar ./jacoco-0.8.5/lib/jacococli.jar execinfo target/jacoco.exec | grep DoubleStreamExTest

Splitting on two files is useful if you don't always merge and want to see runs separately.

Well, I cannot say now whether something did not work for me, or I just failed to check this approach. You may add a comment to the Habr post though :-)

[Godin]

Well, nowadays I only read Habr and stopped commenting on it a long time ago... maybe you can update post? 😉
