Getting exception when running Okta Spring Security & Okta-Hosted Login Page example - github

Question

I followed the steps in this sample code: https://github.com/okta/samples-java-spring/tree/master/okta-hosted-login
When I run the example using the command:
mvn -Dokta.oauth2.issuer=https://{yourOktaDomain}/oauth2/default \ -Dokta.oauth2.clientId={clientId} \ -Dokta.oauth2.clientSecret={clientSecret}
I get the following exception:

I also tried running this sample from my Intellij IDEA IDE and when I open it I get the following error:
'parent.relativePath' of POM com.example.okta:okta-spring-boot-oauth-code-flow-example:0.0.1-SNAPSHOT (C:\Users\fteran\repos\demos\okta-github\samples-java-spring\okta-hosted-login\pom.xml) points at com.okta.examples:aggregator instead of org.springframework.boot:spring-boot-starter-parent, please verify your project structure
I was kind of expecting the sample code to work if I was very careful to follow the instructions, which I think I did, at this point I am not sure if this is an issue on my local or if there is an issue with the sample code itself.

Answer 1

Try this example: https://github.com/okta-samples/okta-spring-boot-sample/
It's more up-to-date.
