Describe the bug
We are successfully authenticating to the OSS Index using the CLI tool but those same credentials do not work for the Maven and Gradle plugins. We arerunning scans in Gitlab CI/CD jobs in the following way:

CLI

.owaspdc.scan.cli:
  script:
    - check_node_duplicate_dependencies
    - dependency-check
      --noupdate
      --enableExperimental
      --disableNodeAuditCache
      --nodeAuditSkipDevDependencies
      --nodePackageSkipDevDependencies
      --ossIndexRemoteErrorWarnOnly true
      --format JSON
      --format HTML
      --suppression suppression.xml
      --exclude $EXCLUDE
      --scan .
      --ossIndexUsername $OSS_USERNAME
      --ossIndexPassword $OSS_API_TOKEN

Maven

.owaspdc.scan.maven:
  script:
    - maven_check_versions
    - ./mvnw org.owasp:dependency-check-maven:check -DdataDirectory=$DATA_DIR -DossIndexUsername=$OSS_USERNAME -DossIndexPassword=$OSS_API_TOKEN

Gradle

.owaspdc.scan.gradle:
  script:
    - *owaspdc-setup
    - gradle_check_versions
    - ./gradlew dependencyCheckAggregate -Ddata.directory=$DATA_DIR -Danalyzers.ossIndex.username=$OSS_USERNAME -Danalyzers.ossIndex.password=$OSS_API_TOKEN

As you can see, all three jobs use the same credentials, but the Maven and Gradle plugins are not able to authenticate.

Version of dependency-check used
The problem occurs using version 12.1.3 of the Gradle and Maven plugins
