Hi, I am attempting to build your okta java spring app using the following cmd (from github sample doc), ```nohighlight xyz:~/environment/samples-java-spring/custom-login (master) $ mvn -Dokta.oauth2.issuer=https://dev-xyz.okta.com/oauth2/default -Dokta.oauth2.clientId=xyz -Dokta.oauth2.clientSecret=xyz [INFO] Scanning for projects...

Hey there! I assume you are referring to the following? [GitHub - okta-samples/okta-spring-boot-sample: Spring Boot + Okta](https://github.com/okta-samples/okta-spring-boot-sample) ---

Yes that is correct … ---

Interesting, I am not able to reproduce the error on my end. Do you see the same issue when you configure and build this sample? You’re looking for a custom self-hosted login implementation rather than okta-hosted (redirect to okta), correct? > **[samples-java-spring/custom-login at master · okta/samples-java-spring](https://github.com/okta/samples-java-spring/tree/master/custom-login)** > > master/custom-login ---

You can safely ignore the warning, that Spring Boot parent pom would be downloaded from Maven Central. The compile error looks real, but I’m guessing that has more to do with the version of Java you are using. Which version are you using? I quickly just tried (without issue): - 11.0.11.9.1-amzn - 8.292.10.1-amzn - 17.0.1.12.1-amzn Anything Java 8+ should work. Keep us posted! ---
