How to write message to Mattermost using Fastlane? - fastlane

Question

How do I write a message to Mattermost using Fastlane ?
Below is my trial. I got most from this link.
What is still wrong ?
(of course, I replaced the MATTERMOST_WEBHOOK_URL by the actual value that I established in Mattermost).
In the link above, I saw an actions folder with a mattermost.rb file
How do I get this action to work ? What do I need to do inside my Fastfile or anywhere in order to get this to work ?
In fact, running the fastlane send_message lane, I get a success. But unfortunately, nothing is visible in my Mattermost channel.
Inside my Fastfile, I do:
def send_message_to_mattermost(options)
unless ENV['MATTERMOST_WEBHOOK_URL'].nil? || ENV['MATTERMOST_WEBHOOK_URL'].empty?
mattermost(
pretext: options[:pretext],
message: options[:msg],
default_payloads: options[:default_payloads],
username: 'Fastlane',
icon_url: 'https://s3-eu-west-1.amazonaws.com/fastlane.tools/fastlane.png',
payload: {},
attachment_properties: {
title: options[:title],
thumb_url: options[:thumb_url],
fields: [{
title: 'Version',
value: options[:version_number],
short: true
},
{
title: 'Build Number',
value: options[:build_number],
short: true
},
{
title: 'Built by',
value: 'Jenkins',
short: true
}]
},
success: options[:success]
)
end
end
And my Fastlane lane looks like this:
lane :send_message do
send_message_to_mattermost({
:version_number => ENV['VERSION_NUMBER'],
:build_number => ENV["BUILD_NUMBER"],
:pretext => ENV['MAIN_APP_IDENTIFIER'],
:title => 'Unsuccessful Build',
:thumb_url => 'https://support.apple.com/library/content/dam/edam/applecare/images/en_US/iOS/move-to-ios-icon.png',
:msg => "My message...",
:default_payloads => [:lane],
:success => true
})
end
Is mattermost(...) a standard command in Fastlane ? If not what do I need to do in order to send information to a Mattermost channel from Fastlane ?

Answer 1

I finally found a solution.
What was missing is to set the ENV["MATTERMOST_WEBHOOK_URL"] upfront
before_all do
ENV["MATTERMOST_WEBHOOK_URL"] = 'https://my_new_webooh_from_mattermost'
end
...and leave the following code intact (i.e. do not replace 'MATTERMOST_WEBHOOK_URL' by anything else - the before_all does the trick...)
def send_message_to_mattermost(options)
unless ENV['MATTERMOST_WEBHOOK_URL'].nil? || ENV['MATTERMOST_WEBHOOK_URL'].empty?
mattermost(
pretext: options[:pretext],
message: options[:msg],
default_payloads: options[:default_payloads],
username: 'Fastlane',
icon_url: 'https://s3-eu-west-1.amazonaws.com/fastlane.tools/fastlane.png',
payload: {},
attachment_properties: {
title: options[:title],
thumb_url: options[:thumb_url],
fields: [{
title: 'Version',
value: options[:version_number],
short: true
},
{
title: 'Build Number',
value: options[:build_number],
short: true
},
{
title: 'Built by',
value: 'Jenkins',
short: true
}]
},
success: options[:success]
)
end
end
