Generation Blocked on GitHub and GitLab

We had a issue were generation of applications are blocked on GitHub and GitLab; #184 and #183. These issues seems to be solved when I added the following code snippet;

jhipster-online/src/main/java/io/github/jhipster/online/service/JHipsterService.java

Lines 102 to 106 in 9c6215d

    
           error = new BufferedReader( 
        
               new InputStreamReader(p.getErrorStream())); 
        
           while ((line = error.readLine()) != null) { 
        
               log.debug(line); 
        
           }

As per the documentation the process can be blocked if we don't read input and output continuously; https://docs.oracle.com/javase/7/docs/api/java/lang/Process.html

However after migrating to app engine flex, it seems that this issue has resurfaced. 😢

	error = new BufferedReader(
	new InputStreamReader(p.getErrorStream()));
	while ((line = error.readLine()) != null) {
	log.debug(line);
	}
