With Custom /.m2/settings.yaml

A user provided custom settings.xml can be used with the Maven Task. To do this we need to mount the settings.xml on the Maven Task. Following steps demostrate the use of a ConfigMap to mount a custom settings.xml.

1. create configmap

apiVersion: v1
kind: ConfigMap
metadata:
  name: custom-maven-settings
data:
  settings.xml: |
    <?xml version="1.0" encoding="UTF-8"?>
    <settings>
      <mirrors>
        <mirror>
          <id>maven.org</id>
          <name>Default mirror</name>
          <url>http://repo1.maven.org/maven2</url>
          <mirrorOf>central</mirrorOf>
        </mirror>
      </mirrors>
    </settings>

or

oc create configmap custom-maven-settings --from-file=settings.xml

2. create TaskRun

apiVersion: tekton.dev/v1alpha1
kind: TaskRun
metadata:
  name: maven-run
spec:
  inputs:
    resources:
      - name: source
        resourceRef:
          name: maven-resource-petclinic
    taskRef:
      name: maven
    workspaces:
    - name: maven-settings
      configMap:
        name: custom-maven-settings
