"target_url must use http(s) scheme"

[dpetzel]

I've recently upgraded Jenkins to 1.609.3 and this plugin to 1.29.2 and I'm getting the error below. I can see that it properly adds a comment when the build starts with a link to the build. The permissions seem correct (and worked before we upgraded)

I've been through the settings and everything looks right to me, but the message is pretty clear that it doesn't like the value being passed for target_url which I presume is null based on the log message. I'm pretty stumped on where to look next. Any help would be appreciated.

Build step 'Execute shell' marked build as failure
Setting status of GUID to FAILURE with url nulljob/MYORG/job/MYREPO/job/MYREPO-pr/30/ and message: 'Build finished. No test results found.'

@dpetzel I am fighting a similar issue with the url. With 1.29.2 you can pass the status-url as --none-- which stops the error but you lose the link on the pull request.

I have been trying to set status-url to the $BUILD_URL but it doesn't seem to be getting evaluated as a variable.

[DavidTanner]

Can you post your config.xml for the job?

[kpettijohn]

My problem was with the $BUILD_URL not being available unless you have Jenkins -> configuration -> Global properties -> Environment variables enabled.

I have also see some cases where not all of the ghprb's global configuration is available unless you open and save the Jenkins -> configuration page.

For example the following at times would result in githubAuth being null, but only on the first converge.

import java.lang.reflect.Field
import jenkins.model.*
import org.jenkinsci.plugins.ghprb.*

def descriptor = Jenkins.instance.getDescriptorByType(org.jenkinsci.plugins.ghprb.GhprbTrigger.DescriptorImpl.class)

Field auth = descriptor.class.getDeclaredField("githubAuth")

auth.setAccessible(true)

githubAuth = auth.get(descriptor)
githubAuth.add(new GhprbGitHubAuth("<%= @server %>", "<%= @credentials_id %>", "<%= @description %>", "<%= @auth_id %>", null)

If you visit the Jenkins -> configuration page and hit apply/save you will no longer receive the null value.

I am not using Jenkins, but I am seeing the exact same issue, but randomly. I am making a call to the status api. The same url, changing the status from pending to success or other, will fail with a 422 20% of the time. I have noticed it just started hitting us harder and harder over the last day or two.

Hi, I also encountered the same problem, the stacktrace is below.

In my case, after resaving "Configure System", the job works well. I hope this information will be helpful for you.

[System Info] Update Jenkins 2.24 to 2.42 Update GitHub Pull Request Builder 1.33.1 to 1.34.0 OS: CentOS6.6

[grav]

It seems the <secret></secret> part of ~/org.jenkinsci.plugins.ghprb.GhprbTrigger.xml is automatically set to something (the correct something), when you visit the Jenkins -> configuration page and hit apply/save, as @kpettijohn noted, which makes the problem go away.

I'm currently adding the secret text credential to Jenkins, as well as setting up the GH PR builder plugin with a .groovy script . I tried using the same secret for both constructors, but it's apparently not the correct string that eventually ends up in the <secret> tag in ~/org.jenkinsci.plugins.ghprb.GhprbTrigger.xml.

If I manually visit the Jenkins -> configuration page and hit apply/save, as @kpettijohn noted, something else is written to the <secret> tag in ~/org.jenkinsci.plugins.ghprb.GhprbTrigger.xml.

This manual step is however a bit of a downer when using automated deployment.

[bjoernhaeuser]

@grav I am not sure how to move on with this. Do you know whats the difference is? I do not see any secret in the GhprbTrigger.

[eswets]

Issue for me was that the $BUILD_URL variable returns null if the base URL of the jenkins instance is not explicitly configured (even though the correct URL was visible in the UI all the time).

For completeness sake, if you're looking to set this URL using Groovy scripts:

import jenkins.model.*

def jenkinsLocationConfiguration = JenkinsLocationConfiguration.get()
jenkinsLocationConfiguration.setUrl("https://www.your.jenkins.instance.com")

jenkinsLocationConfiguration.save()

[soundstep]

Same issue here, trying the fix above in the groovy script.
