I needed to do this as a workaround while running Jenkins via HTTPS, for some reason I was unable to get any GitHub Webhooks to work and would see the following errs in Jenkins log:

jenkins github webhook javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

1. Fetch the certificate from local GitHub:

openssl s_client -connect www.github.com:443 < /dev/null | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > /tmp/github_public.crt

Configure Git to use a proxy

In Brief

You may need to configure a proxy server if you're having trouble cloning or fetching from a remote repository or getting an error like unable to access '...' Couldn't resolve host '...'.

Consider something like:

batmat

def numberOfHoursBack = 7*24

def totalBuildTime =
  Jenkins.instance.getItems(Job.class).collect { job ->
  job.getBuilds().byTimestamp(System.currentTimeMillis()-numberOfHoursBack*60*60*1000, System.currentTimeMillis())
                              }
.flatten()
.collect { build -> build.getDuration() }
.sum()

	protected RestTemplate restTemplate;

	public RemoteApi() {
		restTemplate = new RestTemplate();
		restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter());
	}

	protected HttpHeaders getHttpHeaders() {
		HttpHeaders requestHeaders = new HttpHeaders();

MounteBank for API stubbing

While developing application with external API calls stubs with some logic are mandatory. MounteBank provides bright and simple solution for stubbing HTTP API.

It is possible to start MounteBank server directly from command line and initialize its content with folllowing curl command:

$ mb
$ curl -X POST -d@./src/test/groovy/online4m/apigateway/si/test/imposter.json http://localhost:2525/imposters

Scripted Jenkins Plugins install

Jenkins has a very rich catalog of plugins and it's quite easy to install and update them via UI. BTW, when you want to add tons of plugin via UI, it's a fairly long and boring procedure.

Hopefully, mass installation (or update) could be easy using a simple bash script (curl/python required) :

• https://raw.githubusercontent.com/hgomez/devops-incubator/master/forge-tricks/batch-install-jenkins-plugins.sh

Create a file containing plugins to be installed (or updated), ie iplugins :
