Use maven random port in java cucumber test

I'm using this maven plugin to create a random port for a service and Kafka

				<plugin>
					<groupId>org.codehaus.mojo</groupId>
					<artifactId>build-helper-maven-plugin</artifactId>
					<version>3.4.0</version>
					<executions>
						<execution>
							<id>reserve-network-port</id>
							<goals>
								<goal>reserve-network-port</goal>
							</goals>
							<phase>process-resources</phase>
							<configuration>
								<portNames>
									<portName>kafka.port</portName>
									<portName>service.port</portName>
								</portNames>
							</configuration>
						</execution>
					</executions>
				</plugin>

Then I'm using surfire to run some Integration test

				<plugin>
					<groupId>org.apache.maven.plugins</groupId>
					<artifactId>maven-surefire-plugin</artifactId>
					<version>2.20</version>
					<executions>
						<execution>
							<id>cucumber-tests</id>
							<phase>integration-test</phase>
							<goals>
								<goal>test</goal>
							</goals>
							<configuration>
								<systemPropertyVariables>
									<log.dir>${project.build.directory}/logs</log.dir>
								</systemPropertyVariables>
								<includes>
									<include>**/*Test.java</include>
									<include>**/*Steps.java</include>
									<excludes>**/*cucumber.RunCucumberIT.java</excludes>
								</includes>
								<testFailureIgnore>false</testFailureIgnore>
							</configuration>
						</execution>
					</executions>
				</plugin>

Then in my Cucumber step I'm trying to get it through

var port = System.getProperty("service.port")

But I'm getting null value

Shall I need to set in the surefire plugin to be visible in my cucumber execution?

check this out :

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.20</version>
<executions>
<execution>
<id>cucumber-tests</id>
<phase>integration-test</phase>
<goals>
<goal>test</goal>
</goals>
<configuration>
<systemPropertyVariables>
<log.dir>${project.build.directory}/logs</log.dir>
</systemPropertyVariables>
<includes>
<include>**/*Test.java</include>
<include>**/*Steps.java</include>
<excludes>**/*cucumber.RunCucumberIT.java</excludes>
</includes>
<testFailureIgnore>false</testFailureIgnore>
<!-- you must add this line -->
<argLine>-Dservice.port=${service.port}</argLine> 
</configuration>
</execution>
</executions>
</plugin>

update<br>
you can try moving the execution of the build-helper-maven-plugin before the execution of the maven-surefire-plugin in your POM file!

<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>build-helper-maven-plugin</artifactId>
<version>3.4.0</version>
<executions>
<execution>
<id>reserve-network-port</id>
<goals>
<goal>reserve-network-port</goal>
</goals>
<phase>process-resources</phase>
<configuration>
<portNames>
<portName>kafka.port</portName>
<portName>service.port</portName>
</portNames>
</configuration>
</execution>
</executions>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.20</version>
<executions>
<execution>
<id>cucumber-tests</id>
<phase>integration-test</phase>
<goals>
<goal>test</goal>
</goals>
<configuration>
<!-- Surefire configuration -->
</configuration>
</execution>
</executions>
</plugin>

good luck !
