github-api Getting timeout while connecting to Github API

I have configured a Github App for Jenkins and I am running a Global seed job which would connect to the Github API and retrieve all the repositories in the Organization. Whenever it tries to authenticate to the Github API and retrieve the list of repositories it fails with timeout and the following error is displayed,

Caused: org.kohsuke.github.HttpException: Server returned HTTP response code: -1, message: 'null' for URL: [https://api.github.com/orgs/{orgname}]

Jenkins GitHub plugin should be using okhttp3 everywhere, not HttpURLConnection. Are you using an old version of Jenkins or the GitHub plugin? Or perhaps running on Java 8?

Sep 10 '24 16:09 bitwiseman

@bitwiseman I am on Jenkins 2.468 and Github plugin 1.40.0 and on Java 7 (JDK 17.0.5) .. Is there any compatibility issue in this?

Sep 10 '24 17:09 Mohazinkhan

@bitwiseman I downgraded Github plugin version to 1.34. Still the same issue persists. Appreciate any advise on this.

Sep 11 '24 11:09 Mohazinkhan

@Mohazinkhan JDK 7? Oh, 17. Okay.

What you're seeing is a continuation of #539 and #433 . The library has attempted multiple times to deal with this and things have improved. But the real solution is to not use HttpURLConnection. I'm not sure how it getting instantiated there, but it is.

In the upcoming v2.0 release, we'll be removing HttpURLConnection everywhere.

Sep 11 '24 16:09 bitwiseman

@bitwiseman Thanks for responding. Hmm, I tried every possible thing at my disposal to get rid of this issue, but I just could not. Apart from plugins github, github-api and github-branch-release, is there any other plugin that would be invoking HttpURLConnection?

Also, can you please give some expected timeline on when is this v2.0 release planned?

Sep 11 '24 16:09 Mohazinkhan

@bitwiseman Also, below is the piece of code I am executing to fetch the list of organization repositories using github API, I am using GitHubBuilder method. Could that be the reason for HttpURLConnection?? https://github.com/hub4j/github-api/blob/main/src/main/java/org/kohsuke/github/GitHubBuilder.java#L15C17-L15C34

import javaposse.jobdsl.dsl.DslFactory
import org.kohsuke.github.GHFileNotFoundException
import org.kohsuke.github.GHOrganization
import org.kohsuke.github.GHRepository
import org.kohsuke.github.GitHub
import org.kohsuke.github.GitHubBuilder

class GithubFetcher {

    private final GHOrganization organization
    private final DslFactory dsl
    private static final MAIN_PIPELINE = ["": "Jenkinsfile"]

    private String githubOwner = 'orgname'
    
    GithubFetcher(String token, DslFactory dsl) {
        this.organization = getGithubConnection(token).getOrganization(githubOwner)
        this.dsl = dsl
    }
    
    private static GitHub getGithubConnection(String token) {
        return GitHubBuilder
                .newInstance()
                .withJwtToken(token)
                .build()
    }
    List<GHRepository> getAllRepos() {
        List<GHRepository> allRepos = organization
                .listRepositories(100)
                .findAll { !it.archived }
        dsl.println("All repos ${allRepos.size()}")
        return allRepos
    }

Sep 11 '24 17:09 Mohazinkhan

@Mohazinkhan Oh, so you're running custom code inside Jenkins DSL. That explains it.

Change your code as follows:

import okhttp3.OkHttpClient;
import org.kohsuke.github.extras.okhttp3.OkHttpConnector;

// ...

private static GitHub getGithubConnection(String token) {
    return GitHubBuilder
            .newInstance()
            .withConnector(new OkHttpGitHubConnector(new OkHttpClient.Builder().build()))
            .withJwtToken(token)
            .build()
}

// ...

Sep 12 '24 16:09 bitwiseman

@bitwiseman oh yes, custom code in Jenkins DSL. Thanks so much for the code update. I will try this and update you the results here :)

Sep 12 '24 19:09 Mohazinkhan

@bitwiseman I added the Gradle dependency for okhttp as follows, implementation 'com.squareup.okhttp3:okhttp:4.12.0' and then modified the above lines of code as you provided. Ended up with the java.lang.ClassNotFoundException: okhttp3.OkHttpClient error.

@Mohazinkhan Here's a version with no external dependencies.

import org.kohsuke.github.extras.HttpClientGitHubConnector;

// ...

private static GitHub getGithubConnection(String token) {
    return GitHubBuilder
            .newInstance()
            .withConnector(new HttpClientGitHubConnector()))

Sep 16 '24 14:09 Mohazinkhan

I'm sorry, I can't help you with that. Unexpected channel closing isn't a failure in this library. Maybe your network is having issues? When you figure out a solution please report back.

Sep 16 '24 15:09 bitwiseman

This is not an issue this library can address. Closing.
