Jhipster fails with: "[HPM] Error occurred while trying to proxy request /management/info from localhost:9000 to http://localhost:8080 (ECONNREFUSED)"

Question

I am trying to create a simple project skeleton using jhipster.

# Ubuntu 18.04
node -v
# v10.15.1
npm -v
# 6.4.1
jhipster --version
# 6.0.0
jhipster
# (I only press enter, so that the defaults are selected)
npm start

Now I access the application on port 9000, but when I try to login with admin/admin as prompted, it fails

[HPM] Error occurred while trying to proxy request /management/info from localhost:9000 to http://localhost:8080 (ECONNREFUSED) (https://nodejs.org/api/errors.html#errors_common_system_errors)
[HPM] Error occurred while trying to proxy request /api/account from localhost:9000 to http://localhost:8080 (ECONNREFUSED) (https://nodejs.org/api/errors.html#errors_common_system_errors)
[HPM] Error occurred while trying to proxy request /api/authenticate from localhost:9000 to http://localhost:8080 (ECONNREFUSED) (https://nodejs.org/api/errors.html#errors_common_system_errors)

The same when I try to register a new user from the app.

Is this a bug of the application, or am I doing something wrong?

You aren't launching the backend. https://www.jhipster.tech/development/#running-java-server — Jon Ruddell, May 07 '19 at 15:36

You are only running the frontend, you also need to start backend as @Jon Ruddell comments. On the application directory you have to run:

./mvnw (or mvnw if you are on Windows).

Running the Java server

As a “main” Java class

From your IDE, right-click on the “Application” class at the root of your Java package hierarchy, and run it directly. You should also be able to debug it as easily.

The application will be available on http://localhost:8080.

This application will have “hot reload” enabled by default, so if you compile a class, the Spring application context should refresh itself automatically, without the need to restart the server.

As a Maven project

You can launch the Java server with Maven. JHipster provides a Maven wrapper, so you don’t need to install Maven, and you have the guarantee that all project users have the same Maven version:

./mvnw (on Mac OS X/Linux) of mvnw (on Windows)

(this will run our default Maven task, spring-boot:run)

The application will be available on http://localhost:8080.

Alternatively, if you have installed Maven, you can launch the Java server with Maven:

mvn

If you want more information on using Maven, please go to http://maven.apache.org

(Optional) As a Gradle project

If you selected the Gradle option, JHipster provides a Gradle wrapper, so you don’t need to install Gradle, and you have the guarantee that all project users have the same Gradle version:

./gradlew (on Mac OS X/Linux) of gradlew (on Windows)

(this will run our default Gradle task, bootRun)

Alternatively, if you have installed Gradle, you can launch the Java server with Gradle:

gradle

The application will be available on http://localhost:8080.

If you want more information on using Gradle, please go to https://gradle.org
