newbie question: mvn clean install fails on BindException

[Darren Strachan]

Hi folks,

apologies for the newbie question.  I'm trying to get going with the helloWorld sample app.   I've downloaded Dropwizard and unpacked it into C:\Dropwizard\dropwizard.  Gone into the folder and run "mvn clean install".  It skips along fine until it bugs out on this package:

[INFO] ------------------------------------------------------------------------

I think this is the "core" package.

on going further up to the actual error I see this:

So I guess this is telling me that one of the ports is already in use, and I should either shut down the app that's using it or else change the ports that Dropwizard is trying to use.     So I tried a couple of things:

1) I went through all the .yml files and changed the ports.  This didn't work.... it failed earlier in the build because it seems like some of the tests Assert on the "standard" ports being used

2) I found out that an app on my machine called FrameworkService.exe is using port 8081.  Unfortunately I can't shut this down because it's the Mcafee update app and is controlled by our System Admins.

I guess my next step will be to try to install Dropwizard on a virtualbox over which i have more control.  But if anyone has any suggestions on how to fix this problem i'd be very grateful 

many thanks

In the yaml file of dropwizard you can set application port and admin port, please use some other port in the config.

[Darren Strachan]

hi, thanks for the reply.

when you say the "yaml file of dropwizard", which file is that please?  

when i search for *.yaml files i find these two:

dropwizard\dropwizard-testing\src\test\gzip-vary-test-config.yaml

dropwizard\dropwizard-testing\src\test\test-config.yaml

both of these "port" fields but they are set to zero

there are a whole bunch of *.yml files that do contain port numbers:

Searching for: 808

dropwizard-client\src\test\resources\yaml\bad_auth_password.yml(3): port: 8080

dropwizard-client\src\test\resources\yaml\bad_auth_username.yml(3): port: 8080

dropwizard-client\src\test\resources\yaml\bad_host.yml(3): port: 8080

dropwizard-client\src\test\resources\yaml\bad_scheme.yml(3): port: 8080

dropwizard-client\src\test\resources\yaml\no_auth.yml(3): port: 8080

dropwizard-client\src\test\resources\yaml\no_scheme.yml(3): port: 8080

dropwizard-client\src\test\resources\yaml\proxy.yml(3): port: 8080

dropwizard-configuration\src\test\resources\factory-test-valid.yml(9): - port: 8080

dropwizard-configuration\src\test\resources\factory-test-valid.yml(10): - port: 8081

dropwizard-configuration\src\test\resources\factory-test-valid.yml(11): - port: 8082

dropwizard-configuration\target\test-classes\factory-test-valid.yml(9): - port: 8080

dropwizard-configuration\target\test-classes\factory-test-valid.yml(10): - port: 8081

dropwizard-configuration\target\test-classes\factory-test-valid.yml(11): - port: 8082

dropwizard-example\example.yml(25): #    port: 8080

dropwizard-example\example.yml(32): port: 8080

dropwizard-example\example.yml(46): port: 8081

Found 16 occurrence(s) in 10 file(s)

which of these should i change please?

many thanks in advance for the help!!

While starting a dropwizard app we pass command and some params. 

Generally server path-to-config. 

I think in your case the code which you have downloaded must be invoking main class of application with these commands.

Check which file the test is passing to understand where to change.
