New Orleans will also receive four second-round picks in the swap.
Maker, 21, was the 10th overall pick in the 2016 draft.
First reported by ESPN's Adrian Wojnarowski and Zach Lowe, the Bucks will be acquiring veteran forward Nikola Mirotic in a three-team deal between the Bucks, the Detroit Pistons and the New Orleans Pelicans. The 6-foot-7 small forward out of Arizona was averaging 7.5 points and 3.6 rebounds this season and in four years with the Pistons averaged 7.1 points and 3.5 rebounds.
Through 48 games played with the Pistons this year, majority coming off the bench, Johnson has averaged 7.5 points and 3.6 rebounds per game, while shooting 38 per cent from the field.

Valanciunas, 26, has been the Raptors' starting center and has compiled season averaged of 12.8 points and 7.2 rebounds. Valanciunas hasn't played in almost two months after suffering a dislocated thumb, but is ready to return to the lineup.
He is making a career-high 2.7 shots from 3-point range per game.
Both Harris and star Sixers guard Jimmy Butler, acquired from Minnesota earlier this season, are free agents this off-season while Simmons is in line for a contract extension in the near future.
Johnson played one season of basketball for Arizona before being taken eighth overall by the Pistons in the 2015 draft.
Johnson is joining the league's best defensive team, and in the Bucks' fast-paced offence he may be able to impact the game with his slashing ability.
However, after showing promise last season, Maker had fallen out of head coach Mike Budenholzer's rotation and recently requested a trade. "Johnson can work to find a role on a contending team, and Maker will get an opportunity for playing time with Dwane Casey".
