Quickstart Error

AlexPerrin · March 10, 2020, 11:23pm

I’m following the quickstart guide on Github found here https://github.com/graphhopper/graphhopper/blob/master/docs/web/quickstart.md
but I’m encountering an error when trying to start Graphhopper

I have the files organized like so

after running the command
java -Ddw.graphhopper.datareader.file=ontario-latest.osm.pbf -jar graphhopper-web-0.13.0.jar server config-example.yml

both in CMD and git bash I receive the following errors

        D:\Users\alexp\Downloads\routing>java -Ddw.graphhopper.datareader.file=ontario-latest.osm.pbf -jar graphhopper-web-0.13.0.jar server config-example.yml

The quickstart docs for 0.13 are here: https://github.com/graphhopper/graphhopper/blob/0.13/docs/web/quickstart.md (let me know where you found the wrong master link)

The config.yml format will change for 1.0 (snake_case instead camelCase for 0.13) and also the parameters are slightly different (1.0 requires a dw. prefix)

When you switch to the 0.13 branch, make sure you remove the config.yml otherwise the new config-example.yml won’t overwrite config.yml.

Perfect! The new config got it working

On the Graphhopper Github

I went under the “For the Web” heading and followed the “install it” link to https://github.com/graphhopper/graphhopper/blob/master/docs/index.md

And then under the “For Users” Heading I followed the “this user guide” link to

github.com

graphhopper/graphhopper/blob/master/docs/web/quickstart.md

## Quickstart

If you want to build GraphHopper from source look at the [Developers page](../core/quickstart-from-source.md). 
The following steps are simpler and only need the JRE, a jar file and an OSM file.

 1. Install the latest JRE 
 2. Get the [GraphHopper Web Service](https://github.com/graphhopper/graphhopper/blob/master/README.md#get-started)
as jar file and download this [config-example.yml](https://raw.githubusercontent.com/graphhopper/graphhopper/master/config-example.yml)
 3. Copy an OSM file to the same directory. For example [berlin-latest.osm.pbf](http://download.geofabrik.de/europe/germany/berlin.html)
 4. Start GraphHopper Maps via: 
    ```bash
    java -Ddw.graphhopper.datareader.file=berlin-latest.osm.pbf -jar *.jar server config-example.yml
    ```
 5. After you see 'Started server at HTTP 8989' go to [http://localhost:8989/](http://localhost:8989/) and you should see a map of Berlin. You should be able to click on the map and a route appears.

See [here](./../core/elevation.md) how to easily enable elevation data. To see how GraphHopper is configured for production usage, see the [deployment guide](./../core/deploy.md).

## Troubleshooting

 * Make sure JRE8 is installed. If not get Java [here](http://java.com).

Ah, thanks. This should indeed not link to the master docs. Will fix that.

Sorry but I still get this error with both config-example.yml
