importMergeRequestMergeCommits: aGLPHEMergeRequest

	| foundCommits |
	foundCommits := OrderedCollection new.

	('Import commit sha of MR:  ' , aGLPHEMergeRequest iid printString)
		recordInfo.
	"the founds commits are added to the model during their respective import"
	aGLPHEMergeRequest mergeRequestCommit: ((self
			  importCommitOfProject: aGLPHEMergeRequest project
			  withId: aGLPHEMergeRequest sha) ifNotNil: [ :commit |
			 foundCommits add: commit ]).
