The command "yes | sdkmanager --licenses" failed, Android Kotlin

So this is my first dip into the CI waters and I’ve had a rough time. This is my travis.yml inside my Android application in Android Studio using Kotlin. I’ve tried googling quite a bit but I couldn’t find any useful info on the topic. Doesn’t seem like a common problem, or it’s easily solvable.

language: android
jdk: oraclejdk8
env:
  global:
    - ANDROID_API_LEVEL=25
    - ANDROID_BUILD_TOOLS_VERSION=29.0.2
android:

    - 'android-sdk-preview-license-.+'
    - 'android-sdk-license-.+'
    - 'google-gdk-license-.+'

Error: Unknown argument --licenses

Usage: 

  sdkmanager [--uninstall] [<common args>] \

    [--package_file <package-file>] [<packages>...]

  sdkmanager --update [<common args>]

  sdkmanager --list [<common args>]

In its first form, installs, or uninstalls, or updates packages.

    <package> is a sdk-style path (e.g. "build-tools;23.0.0" or 

             "platforms;android-23").

    <package-file> is a text file where each line is a sdk-style path

                   of a package to install or uninstall.

    Multiple --package_file arguments may be specified in combination

     with explicit paths.

In its second form (with --update), currently installed packages are

    updated to the latest version.

In its third form, all installed and available packages are printed out.

Common Arguments:

    --sdk_root=<sdkRootPath>: Use the specified SDK root instead of the SDK containing this tool

    --channel=<channelId>: Include packages in channels up to <channelId>.

                           Common channels are:

                           0 (Stable), 1 (Beta), 2 (Dev), and 3 (Canary).

    --include_obsolete: With --list, show obsolete packages in the

                        package listing. With --update, update obsolete

                        packages as well as non-obsolete.

    --no_https: Force all connections to use http rather than https.

    --proxy=<http | socks>: Connect via a proxy of the given type.

    --proxy_host=<IP or DNS address>: IP or DNS address of the proxy to use.

    --proxy_port=<port #>: Proxy port to connect to.

* If the env var REPO_OS_OVERRIDE is set to "windows",

  "macosx", or "linux", packages will be downloaded for that OS.
