What are you seeing?
When running tests for the NUnit console runner with arguments --target=Test --target=Package the Build target is run twice, once before Test and once before Package. Build is, of course, a dependency of both targets.
I would expect the dependent target to run only once
NOTE: This appears to be related to #4066.
Steps to Reproduce
Use the following script:
var targets = Arguments<string>("target", "A");
Task("A")
.Does(() => Information("Running A"));
Task("B")
.IsDependentOn("A")
.Does(() => Information("Running B"));
Task("C")
.IsDependentOn("A")
.Does(() => Information("Running C"));
RunTargets(targets);
Run using arguments --target=B --target=C
This produces the following output:
========================================
A
========================================
Running A
========================================
B
========================================
Running B
========================================
A
========================================
Running A
========================================
C
========================================
Running C
