To apply for a visa to visit Jamaica the following documents are required:

If the person inviting you is also sponsoring the trip financially and/or providing accommodation, an Affidavit of Guarantor form is also required:

Coming from Nigeria, youβll also need to provide proof of Yellow fever vaccination: http://www.jhcuk.org/visitors/yellow-fever-entry-requirement
The typical rule is to apply for your visas in reverse order, starting with your final destination and then working backwards through your transit point(s), each of which will want to see evidence that you have the necessary permission to enter your onward destination.
When making visa applications, it is essential to present credible plans and usually best to keep things as simple as possible. As @jcaron has commented, if you are granted a Jamaican visa, applying for a visa to transit airside in Heathrow becomes possible. Therefore, if I were you, I would avoid the more complicated flight options and I would present a flight itinerary via Heathrow; once you receive your Jamaican visa you can then apply for a Direct Airside Transit visa https://www.gov.uk/transit-visa/direct-airside-transit-visa, which costs Β£35.
If the UK refuses you an airside transit visa, you will still have your Jamaican entry visa and can look for an alternative, such as those mentioned in various comments.

Assuming you are a Nigerian citizen, this will be very difficult.
You will need to find a routing that only touches countries that offer visa free transit for Nigerians and there aren't many. Most long haul flight to Jamaica either come from Europe or from North America and most countries will require a transit visa. The other options are going through a different Caribbean country or maybe Panama, but you need to figure out how to get there first.
Unfortunately the requirements aren't well documented so this will be a tedious search. You can put different itineraries together and then check them at https://www.iatatravelcentre.com/passport-visa-health-travel-document-requirements.htm
I did quick search and there was only one-stop flight between Lagos and Montego Bay was Virgin Atlantic through London Heathrow, which does require a Direct Airside Transit Visa for Nigerians.
