How pass the parameter from pom.xml to java class dynamically when executing in jenkins

Question

POM.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>

  <groupId>Imageproceesing</groupId>
  <artifactId>beginner</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <packaging>jar</packaging>

  <name>beginner</name>
  <url>http://maven.apache.org</url>

  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <environment>${env}</environment>
  </properties>

  <dependencies>
  <!-- https://mvnrepository.com/artifact/net.sourceforge.tess4j/tess4j -->
<dependency>
    <groupId>net.sourceforge.tess4j</groupId>
    <artifactId>tess4j</artifactId>
    <version>4.4.1</version>
</dependency>

    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>4.11</version>
      <scope>test</scope>
    </dependency>
  </dependencies>
</project>

Environment is the parameter i'm going to pass via

mvn clean test -Denv=dev

in Test class

public class AppTest 
{
    @Test
    public void demo()
    {
        String environment=System.getProperty("environment");
        if(environment.equals("dev"))
           //...rest code here
        System.out.println("check the code");
    }
}

I'm in need to pass the environment variable from command line to pom and to Java, but every time I'm getting null.

You can inject properties into your tests by configuring the surefire plugin, as in:

...
  <groupId>use-surefire</groupId>
  <artifactId>use-surefire</artifactId>
  <version>0.0.1-SNAPSHOT</version>

  <properties>
    <environment>${env}</environment>
  </properties>
  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>4.12</version>
      <scope>test</scope>
    </dependency>
  </dependencies>
  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
        <version>2.22.0</version>
        <configuration>
          <systemPropertyVariables>
            <environment>${environment}</environment>
          </systemPropertyVariables>
        </configuration>
      </plugin>
    </plugins>
  </build>
</project>
