Current Behavior

  • we introduce a feature to allow circular project dependencies to execute tasks in pr https://github.com/nrwl/nx/pull/28227/files
  • for this feature, we introduce the concept of dummy task as a temporary placeholder so we can still generate a task graph even if dependencies contain circular dependencies
  • however, it does not handle a task graph of multiple dummy task deps. for example:
    lib1 -> lib2 -> lib3 -> lib4
    if we got task graph like:
    lib1:build -> lib2:dummy
    lib2:dummy -> lib3:dummy
    lib3:dummy -> lib4:rebuild
    currently, it does not create a dependency between lib1:build->lib4:prebuild

Expected Behavior

it should link the dependency when it contains multiple level of depending on dummy tasks

## Current Behavior
<!-- This is the behavior we have today -->
- we introduce a feature to allow circular project dependencies to
execute tasks in pr https://github.com/nrwl/nx/pull/28227/files
- for this feature, we introduce the concept of dummy task as a
temporary placeholder so we can still generate a task graph even if
dependencies contain circular dependencies
- however, it does not handle a task graph of multiple dummy task deps.
for example:
lib1 -> lib2 -> lib3 -> lib4
if we got task graph like:
lib1:build -> lib2:dummy
lib2:dummy -> lib3:dummy
lib3:dummy -> lib4:rebuild
currently, it does not create a dependency between
lib1:build->lib4:prebuild

## Expected Behavior
<!-- This is the behavior we should expect with the changes in this PR
-->
it should link the dependency when it contains multiple level of
depending on dummy tasks
