If you’d like to connect to your organization’s internal maven repository, you can override the default repository location by passing the credentials via the following environment properties:

export MAVEN_LOCAL_REPOSITORY=mylocalMavenRepo
export MAVEN_REMOTE_REPOSITORIES_REPO1_URL=https://repo1
export MAVEN_REMOTE_REPOSITORIES_REPO1_AUTH_USERNAME=user1
export MAVEN_REMOTE_REPOSITORIES_REPO1_AUTH_PASSWORD=pass1
export MAVEN_REMOTE_REPOSITORIES_REPO2_URL=https://repo2

If you are running behind a proxy, then you need to specify the proxy settings via environment properties like this:

export MAVEN_PROXY_PROTOCOL=https
export MAVEN_PROXY_HOST=host1
export MAVEN_PROXY_PORT=8090
export MAVEN_PROXY_NON_PROXY_HOSTS='host2|host3'
export MAVEN_PROXY_AUTH_USERNAME=user1
export MAVEN_PROXY_AUTH_PASSWORD=passwd

Alternatively, you can pass them wrapped inside SPRING_APPLICATION_JSON environment property like the following:

export SPRING_APPLICATION_JSON='{ "maven": { "local-repository": null,"remote-repositories": { "repo1": { "url": "https://repo1", "auth": { "username": "repo1user", "password": "repo1pass" } }, "repo2": { "url": "https://repo2" } }, "proxy": { "host": "proxyhost", "port": 9018, "auth": { "username": "proxyuser", "password": "proxypass" } } } }'

Formatted JSON:

SPRING_APPLICATION_JSON='{
  "maven": {
    "local-repository": null,
    "remote-repositories": {
      "repo1": {
        "url": "https://repo1",
        "auth": {
          "username": "repo1user",
          "password": "repo1pass"
        }
      },
      "repo2": {
        "url": "https://repo2"
      }
    },
    "proxy": {
      "host": "proxyhost",
      "port": 9018,
      "auth": {
        "username": "proxyuser",
        "password": "proxypass"
      }
    }
  }
}'

	Note
	Depending on Spring Cloud Data Flow’s server implementation, you may have to pass the environment properties using the platform specific environment-setting capabilities. For instance, in Cloud Foundry, you’d be passing them as cf set-env SPRING_APPLICATION_JSON, cf set-env MAVEN_REMOTE_REPOSITORIES_REPO1_URL etc.
