How to run specific profile ID / suites (to run specific TestNG.xml) in Gradle?

Question

I am new to Gradle, but I know in Maven we can run specific profile. In my case, I have 2 TestNG.xml files and in Maven POM.xml I can write like this

<profiles>
        <profile>
            <id>FirstRegression</id>
            <build>
                <plugins>
                    <plugin>
                        <groupId>org.apache.maven.plugins</groupId>
                        <artifactId>maven-surefire-plugin</artifactId>
                        <version>2.18.1</version>
                        <configuration>
                            <suiteXmlFiles>
                                <suiteXmlFile>testng1.xml</suiteXmlFile>
                            </suiteXmlFiles>
                        </configuration>
                    </plugin>
                </plugins>
            </build>
        </profile>
        <profile>
            <id>SecondRegression</id>
            <build>
                <plugins>
                    <plugin>
                        <groupId>org.apache.maven.plugins</groupId>
                        <artifactId>maven-surefire-plugin</artifactId>
                        <version>2.18.1</version>
                        <configuration>
                            <suiteXmlFiles>
                                <suiteXmlFile>testng2.xml</suiteXmlFile>
                            </suiteXmlFiles>
                        </configuration>
                    </plugin>
                </plugins>
            </build>
        </profile>
    </profiles>

In command line , we can choose which profile (which TestNG.xml file) we want to run. mvn test -PFirstRegression will execute our testng1.xml file only, meanwhile mvn test -pSecondRegresion will execute our testng2.xml file only.

How can we do this in build.gradle file ? so we can choose which profile to run in gradle.

I can put like this in build.gradle

plugins {
     id 'java'
 }

test {
     useTestNG() {
         suites 'testng1.xml'
         suites 'testng2.xml'
     }
 }

But when I run gradle clean build , it will run both of them. Is there anyway we can say gradle clean build --"please run testng2.xml only" ? Thank You.
