java.lang.IllegalStateException: Failed to load property source from location 'classpath:/application.yml'

Question

I am getting below error for the Spring Cloud project. In this project I am not doing anything special other than reading the .properties files from the GIT.

Please guide on what else need to be corrected out here ?

How we can solved the below error ? application.yml

This error indicates an issue with the formatting of the application.yml You can validate your yml file online: http://www.yamllint.com/

If we use sublime, we could pick pretty yaml, which can easily set the syntax correct

In case the other answers didn't help and you are using IntelliJ like me, try reloading the Gradle project, that fixed it for me.

Try removing quotes

server:
  port: 8888

spring:
  cloud:
    config:
      server:
        git:
          uri: https://github.com/rseroter/pluralsight-spring-cloudconfig-wa-tolls

          search-paths:
          - 'station*'
          repos:
            perf:
              pattern: 
                - */perf ##as it was trying to match the whole pattern
                uri: https://github.com/rseroter/pluralsight-spring-cloudconfig-wa-tolls-perf

                search-paths:
                - 'station*'

If still not works, please try the below

repos:
  perf:
    pattern: xx*/perf, */pref ##as the fist character can't be a wild card but it can accept multiple value.
    uri: https://github.com/rseroter/pluralsight-spring-cloudconfig-wa-tolls-perf

Also it is important to look for correct indentation while working with yml files.

I got that error today, and I didn't understand at first because the indentation of my conf was good. Then I realized that was because the encoding of my application.yml was "Microsoft something" (suggested by IntelliJ, don't remember exactly). I just copied my conf, pasted it in SublimeText, deleted my application.yml, then recreated a new file with the same name (so application.yml), copied what was in SublimeText, then pasted it in my new file. Apparently the default encoding fixed the problem.

I have the same problem and fix it already. If the application.yml file is well done, you can try to empty your maven repository(at Maven/repository).then do maven update at your project and run it again.

I'm not sure about the second search-paths, I think you put that in there by mistake. But for the error messages in line 17 & 18, that's an easy fix:

Add another dash to the line containing the uri, so that it looks like that:

repos:
        perf:
          pattern: 
            - */perf ##as it was trying to match the whole pattern
            - uri: https://github.com/rseroter/pluralsight-spring-cloudconfig-wa-tolls-perf

What comes after pattern: is supposed to be a list and you need to prefix the items with -.

I was facing the similar issue... the one of the reason is not giving proper spacing in yaml file. I have resolved as below -

Example -

incorrect one ->
    RESERVATION:
      registerHealthIndicator: true
        slidingWindowSize: 100   --> this parameter have unnecessary spaces at beginning

the correct one is ->

    RESERVATION:
      registerHealthIndicator: true
      slidingWindowSize: 100      --> correct as spaces at beginning removed

Refer below image -

If, in the future, anyone else has a problem with the coding, I ask you to check the comments in the application.yml

I have a grails application that runs normally with grails run-app, but the .war file was not running.

I found that a link, in a comment, was causing the exception below, even with yml without errors.
