Android SDK installation fails

When installing and updating the Android SDK, the installation fails, because an obsolete flat (-o) is used. I think it should use --all.

Here's a log:

[android] Searching for Android projects...
[android] Project file 'project.properties' requires platform 'android-15'
[android] No Android SDK found; let's install it automatically...
Downloading and installing Android SDK from http://dl.google.com/android/android-sdk_r21.0.1-macosx.zip
[android] Base SDK installed successfully
[android] Going to install required Android SDK components...
[android] Installing the 'platform-tool,tool' SDK component(s)...
$ /Users/hugo/Code/jenkins/slave/tools/android-sdk/tools/android update sdk -u -o -t platform-tool,tool
Error: Flag '-o' is not valid for 'update sdk'.

Usage:
android [global options] update sdk [action options]
Global options:
-h --help : Help on a specific command.
-v --verbose : Verbose mode, shows errors, warnings and all messages.
--clear-cache: Clear the SDK Manager repository manifest cache.
-s --silent : Silent mode, shows errors only.

Action "update sdk":
Updates the SDK by suggesting new platforms to install if available.
Options:
--proxy-port: HTTP/HTTPS proxy port (overrides settings if defined)
--proxy-host: HTTP/HTTPS proxy host (overrides settings if defined)
-s --no-https : Uses HTTP instead of HTTPS (the default) for downloads.
-a --all : Includes all packages (such as obsolete and non-dependent
ones.)
-f --force : Forces replacement of a package or its parts, even if
something has been modified.
-u --no-ui : Updates from command-line (does not display the GUI)
-p --obsolete : Deprecated. Please use --all instead.
-t --filter : A filter that limits the update to the specified types of
packages in the form of a comma-separated list of
[platform, system-image, tool, platform-tool, doc, sample,
source]. This also accepts the identifiers returned by
'list sdk --extended'.
-n --dry-mode : Simulates the update but does not download or install
anything.
