Starting with JHipster

Question

this is my first post on here. I generally try to find everything myself but I feel like I've hit every possible wall. I apologize if I'm not specific enough but hope someone here can help me. I just started using jHipster and have successfully generated a project and have also added it to IntelliJ IDEA (using the trial edition). Unfortunately I have not been able to get the application to run. I continue to receive this error (had to cut down to fit in the character constraints):

These are just the beginning of errors I have received. I have followed the all of the setup procedures listed on the jHipster website including installing node.js, npm, bower, yo, grunt, maven, git. I am attempting to use Java 8 for this but don't see what the problem is that I can't run an unchanged generated project without errors. I followed instructions to add Spring to the module project structure but to no avail. The project will make and compile but will not run. Running "grunt serve" starts up an empty server and using mvn spring-boot:run closes with the errors listed above which is the same as just trying to run the Java application. Just to note I have also attempted to use Eclipse with the same errors. If anyone needs more information in helping me with this error I'd be more than happy to provide any necessary details. I can figure out what to do after getting the application to run but just can't get it to that point. If anyone can be of any assistance I'd more than appreciate it. Thanks everyone!

Answer 1

It looks like the error is with connecting to your postgres server. Make sure you have a postgres running with database name as defined in application.yml. If you don't want to use postgres, you can configure jHipster to use an embedded H2 database.

This is the segment of the error trace that is relevant :

com.zaxxer.hikari.pool.PoolInitializationException: Exception during
 pool initialization: Connection to localhost:5432 refused. Check that
 the hostname and port are correct and that the postmaster is accepting
 TCP/IP connections.
