They led each of the last three games by more than 13 points only for the Warriors to stage comebacks and snatch victory.
The Trail Blazers had a 17-point lead late in the third-quarter in game four and All-Star guard Damian Lillard had a chance to win the game at the end of regulation and in overtime but his final-second shots missed.
The Warriors' Steph Curry, with 37 points, had his fourth-straight game of 35-points or more.
Portland's centre Meyers Leonard had a monster game with 30 points and 12 rebounds while Lillard added 28 points.
The Warriors, who beat the Cavs for titles in 2017 and 2018, are favourites to three-peat.
They will play the winner of the Eastern Conference finals between the Milwaukee Bucks and the Toronto Raptors. The Bucks lead 2-1.
