FailSafe plugin is not running feature files in parallel

Question

I have included failsafe plugin with parallel methods and threadcount 4. And framework is cucumber with junit. I'm trying to run features in parallel with failsafe plugin of maven. i have different profiles for different environments and use maven verify goal with command

verify -D environment=int 

<profile>
    <id>int</id>
    <activation>
        <property>
            <name>environment</name>
            <value>int</value>
        </property>
    </activation>
    <properties>
        <env.info>int</env.info>
    </properties>

                </executions>
            </plugin>
        </plugins>
    </build>
</profile>

My test runner class is defined like this

@RunWith(Cucumber.class)
@CucumberOptions(features = {"src/test/resources/feature/"},
        glue = {"com.stepdefinition"},
        plugin = {"pretty",
                "html:target/report.html",
                "json:target/json/report.json",
                "rerun:target/rerun.txt"},
         tags = "@continuousDataloggerLineChartInt or @trendLineChartInt or @standardDataloggerLineChartInt",
        dryRun = false
)

public class TestRunner {
}   

features folder structure:

issue is build is successful and tests are running but not in parallel mode.

what can I do here?
