Branch
master

Travis CI make example of a pipeline of one step.

Explanation

First, we specify in the Makefile that when we do make, the success is dependent on output.txt:

all: output.txt

Second, we specify in the Makefile that output.txt is dependent on intermediate.txt. If intermediate.txt changes, it will be copied to output.txt, after which some text is appended.

output.txt: intermediate.txt
	cp intermediate.txt output.txt
	echo "cool" >> output.txt

Third, we specify in the Makefile that intermediate.txt is dependent on input.txt. If input.txt changes, it will be copied to intermediate.txt, after which some text is appended.

intermediate.txt: input.txt
	cp input.txt intermediate.txt
	echo "is" >> intermediate.txt
