Process pr = run.exec("./JMeter/apache-jmeter-4.0/bin/jmeter -n 
-t ./JMX/"+FileName+" -l ./JTL/Generate_Dashboard.jtl -e -o 
./Result/"+Name+""");

InputStreamReader(pr.getInputStream()));
String line = "";
while ((line=buf.readLine())!=null) {
        System.out.println(line);
    }

1. You need to launch jmeter.sh script instead of jmeter , it performs environment check, sets up variables, JVM options when it comes to Java 9, etc.

2. You need to ensure that both jmeter.sh and jmeter have execute permissions , ie execute the following command:

    chmod +x /JMeter/apache-jmeter-4.0/bin/jmeter && chmod +x /JMeter/apache-jmeter-4.0/bin/jmeter.sh 

3. I don't think you need these dots in your command, to wit you need to amend your command to look like:

    Process pr = run.exec("/JMeter/apache-jmeter-4.0/bin/jmeter -n -t /JMX/"+FileName+" -l /JTL/Generate_Dashboard.jtl -e -o /Result/"+Name+""");
