Run
mvn clean verify
But in target folder not exist jacoco's coverage report

Answer 1

Since your profile is not activated by default, you need to specify -Pcoverage to your maven command to run this profile.
mvn clean verify -Pcoverage
You can also activate your coverage profile by adding the following to your pom.xml
<profile>
<id>coverage</id>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<!-- Rest of the Profile build configuration -->
</profile>
