Skipping JaCoCo execution due to missing execution data error

You need to add ${argLine} to surefire plugin configuration. Example:

        <build>            <plugins>                <plugin>                    <groupId>org.jacoco</groupId>                    <artifactId>jacoco-maven-plugin</artifactId>                    <version>0.7.1.201405082137</version>                    <executions>                        <execution>                            <goals>                                <goal>prepare-agent</goal>                            </goals>                        </execution>                        <execution>                            <id>report</id>                            <phase>prepare-package</phase>                            <goals>                                <goal>report</goal>                            </goals>                        </execution>                    </executions>                </plugin>                <plugin>                    <artifactId>maven-surefire-plugin</artifactId>                    <version>2.14.1</version>                    <configuration>                        <argLine>${argLine}</argLine>                    </configuration>                </plugin>            </plugins>        </build>

If you want you can add other params to the surefire plugin like that:

<argLine>${argLine} -XX:PermSize=128m -XX:MaxPermSize=512m</argLine>

Another reason for missing jacoco.exec can be that there aren't any unit tests in project.

Edit:I would like to know, why my answer was voted down since nobody left any reason in comments.We had the same error message in project consisting of 3 sub-projects. One of them was new and without any tests - after adding one dummy unit test error was gone.

change your <profile>'s <build> to, note: use latest version for jacoco-maven-plugin
