I am Having Java 7 in my system as Default Configuration. But I have to use Java 8 only for spring boot.
The below command is working fine in my terminal.
ubuntu@karthick:~$ JAVA_HOME=/opt/jdk1.8.0_181 mvn spring-boot:run
But When I tried to execute it from Process Builder it is showing error.
Code:
ProcessBuilder pb = new ProcessBuilder("JAVA_HOME=/opt/jdk1.8.0_181", "mvn", "spring-boot:run");
pb.directory(new File("/home/ubuntu/project/springbootexample"));
Process p = pb.start();
I am getting the Below Error
error=2, No such file or directory. Stacktrace follows:
java.io.IOException: error=2, No such file or directory

How to resolve the issue?
I would suggest create a script file(test.sh below) in which you can set java home and add other command to run spring boot and just invoke that script from java using below code:
String[] args = { "/bin/bash", "test.sh"};
StringBuilder builder = new StringBuilder();
Process p2 = null;
String result = null;
String[] cmd = { "sudo", "-s" };
Runtime.getRuntime().exec(cmd);
p2 = Runtime.getRuntime().exec(args);
BufferedReader reader = new BufferedReader(new
InputStreamReader(p2.getInputStream()));
String line;
while ((line = reader.readLine()) != null) {
builder.append(line);
}
result = builder.toString();
