Proxy and Certificate Configuration

To configure proxies, edit the settings.xml file for your Maven setup, as specified in [https://maven.apache.org/guides/mini/guide-proxies.html].

<settings>
    .
    .
    <proxies>
    <proxy>
        <id>example-proxy</id>
        <active>true</active>
        <protocol>http</protocol>
        <host>proxy.example.com</host>
        <port>8080</port>
        <username>proxyuser</username>
        <password>somepassword</password>
        <nonProxyHosts>www.google.com|*.example.com</nonProxyHosts>
    </proxy>
    </proxies>
    .
    .
</settings>

For configuring certificates for Maven, see: [https://maven.apache.org/guides/mini/guide-repository-ssl.html].

Credentials Configuration

To specify credentials, you need a credentials file.

Sample credentials file:

---
schemaVersion: v1
kind: Credentials

metadata:
  name: Registry Credentials
  version: v1
  description: Sample credentials file

credential_required_services:
  - url: registry.gitlab.com
    user_env: CI_REGISTRY_USER
    pass_env: CI_REGISTRY_PASSWORD

Experimental Maven Collector Plugin

An experimental Maven artifact collector plugin can be enabled through use of the --experimental or -x command line option to hopctl, or by setting the HOPPR_EXPERIMENTAL environment variable to a non-empty value (typically "1" by convention).

The experimental plugin does not depend on the presence of the mvn command line tool; it collects artifacts using web requests to the repository endpoint(s) specified in the manifest file.

Configuration Options (Experimental)

There are no additional transfer file configuration options for the experimental Maven collector plugin.

Proxy and Certificate Configuration (Experimental)

No settings.xml configuration is required, but the following environment variables should be set if necessary.

Variable	Details
HTTP_PROXY / http_proxy	Proxy server and port to use for HTTP web requests
HTTPS_PROXY / https_proxy	Proxy server and port to use for HTTPS web requests
NO_PROXY / no_proxy	Comma-separated list of hostname patterns that should bypass the proxy server
REQUESTS_CA_BUNDLE	Path to file containing trusted certification authority certificates

Credentials Configuration (Experimental)

Credentials are configured as outlined in Credentials Configuration.
