If you need to track a package with Composer but it doesn't exist in a repository, you can still manage it with Composer. Simply create a custom repository of type 'package', add it to your required packages, and proceed as normal.

1. Open your composer.json and add a a block to the 'repositories' array like the following.

{
  "repositories": [
    {
      "type": "package",

About

HTTPS and Personal Access Tokens are the preferred method to use GitHub, rather than SSH keys. Here I'll explain why.

SSH key problems

Accepting Host Keys

If you access GitHub using SSH, you're required to accept the host keys of github.com the first time you pull a repo. This might not be a problem if you're using your own workstation, as the cached host keys will stick around for a long time.

Plugins

What plugins are installed on my Jenkins server?

• There are "Downloaded plugins" and there are "Bundled plugins".
  • Bundled plugins come in the jenkins.war file which contains the Jenkins Core code. You may need to check for security updates for these separate from your downloaded plugins. When you change your Jenkins Core version, you'll want to re-check these plugins.
  • Downloaded plugins must be downloaded and installed aside from the jenkins.war file.
• Plugins can have a .jpi' or .hpi file extension.
