undefined method `getQuietPeriod' for nil:NilClass when testing the /build_now/project-name webhook

[gtheraud]

I added following webhooks for Push and Tag Push Events in gitlab :

http://jenkins.local/gitlab/build_now/my-project

my-project is a Jenkins Pipeline project. When i test the webhooks, i get the following HTTP Response :

NoMethodError at /build_now/my-project
undefined method `getQuietPeriod' for nil:NilClass
file: api.rb location: POST /build_now/:project_name line: 43

with the following stack-trace :

This issue might be linked to #31 since my build is a Pipeline build.
I found out that there might be a bug in models/services/get_jenkins_projects.rb :

projects = Java.jenkins.model.Jenkins.instance.getAllItems(AbstractProject.java_class).map do |jenkins_project|

This won't return the pipeline jobs. When I removed AbstractProject.java_class to include pipeline jobs, i get :

undefined method 'scm' for OrgJenkinsciPluginsWorkflowJob::WorkflowJob

Unfortunately, that is how much I can do so far.

I also had the same problem,my gitlab web hooks is
http://site/gitlab/build_now/projectName
jenkins 2.20

I had the same problem, but found a workaround. I use the same web hook as @wuzhaozhongguo, but I opened the project configuration screen in Jenkins and copied the 'Project name' field from there. After that it worked.

Before: http://<site>/gitlab/build_now/BO_Merge_Request_Build
After: http://<site>/gitlab/build_now/bo_merge_request_build

Looks like it might be a case issue.

I'm on gitlab-hook-plugin v1.4.2, Jenkins 2.7.3.

Hope that helps.
