Complex Regex conversion from PHP to Java

Question

I was using a pattern in PHP that was working properly. But in Java, I have tried to convert without success.

This is the PHP Regex :

$pattern = "/^docker-pullable:\\/\\/docker-registry.default.svc:5000\\/(.*)\\/(.*)@(.*)$/";

What I tried in Java :

String pattern = "^docker-pullable:\\\/\\\/docker-registry.default.svc:5000\\\/(.*)\\\/(.*)@(.*)$";

The String :

String myString = "docker-pullable://docker-registry.default.svc:5000/project-d/mo@sha256:ed651abfd1f67130ace2b7b3a3h6hdjzpms230fee8f55b16677c4785fad88021";

The code :

Pattern p = Pattern.compile(pattern);
Matcher m = p.matcher(myString);
if(m.find()){
  String n1= m.group(1); // return project-d
  String n2= m.group(2); // return mo
  String n3= m.group(3); // return Sha
}

I do not find any converter tool from PHP to Java :( And not a doc that is simple ..

Thanks
