Jacoco code coverage report showing wrong

When I run individual test classes, it shows 100% coverage where as when I taken maven build for whole project then Jacoco report showing wrong coverage percentage for many classes. Is there a way to get jacaco report per test class?

Below is my pom configuration

      <plugin>
            <groupId>org.jacoco</groupId>
            <artifactId>jacoco-maven-plugin</artifactId>
            <version>0.8.6</version>
            <executions>
                <execution>
                    <id>default-prepare-agent</id>
                    <goals>
                        <goal>prepare-agent</goal>
                    </goals>
                </execution>
                <execution>
                    <id>default-report</id>
                    <goals>
                        <goal>report</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
