"NoClassDefFoundError: com/github/scribejava/java8/base64/Java8Base64" error

[lennygokhman]

Hi,

I'm trying to use the YahooApi20 to authenticate via OAuth2.0. This example file I'm able to compile and run in Eclipse: https://github.com/scribejava/scribejava/blob/master/scribejava-apis/src/test/java/com/github/scribejava/apis/examples/Yahoo20Example.java. The service builder successfully gives me a url to authorize, I goto the site, get verifier, paste into terminal, then get the following exception on this piece of code:

final OAuth2AccessToken accessToken = service.getAccessToken(oauthVerifier);

Exception in thread "main" java.lang.NoClassDefFoundError: com/github/scribejava/java8/base64/Java8Base64

I've made sure to import commons-codec-1.15, along with scribejava-apis-8.3.1 and scribejava-core-8.3.1 and I'm on Java 11. Any help would be greatly appreciated

Hey lennygokhman,

I also ran into this issue and resolved it by also including the scribejava-java8 jar in my project.
