[bug] moon.yml dependsOn does not work as expected

[sharpepd]

In the docs https://moonrepo.dev/docs/config/project#dependson it says "The most common use case for this is building those projects before building this one". I am unsure what that really means and the behaviour I am seeing does not fit with what I would expect.

If I have two projects app1 & app2 and app1 is dependent on app2, then I am expecting ALL tasks of app2 to be completed before app1 tasks are attempted.

But this is not what I am observing.

Steps to reproduce

I setup a simple moon set-up:

workspace.yml

projects:
  - 'apps/*'

apps/app1/moon.yml

dependsOn:
  - app2
tasks:
  build:
    script: 'echo "Building app1"'
  deploy:
    script: 'echo "Deploying app1"'
    deps: 
    - build

apps/app2/moon.yml

tasks:
  build:
    script: 'echo "Building app2"'
  deploy:
    script: 'echo "Deploying app2"'
    deps: 
    - build

When I run moon run :deploy --summary

I get the running order (summary only shown)

pass SyncWorkspace (1ms)
skip SetupToolchain(system) (skipped, 2ms)
pass SyncProject(system, app2) (1ms)
pass SyncProject(system, app1) (2ms)
pass RunTask(app2:build) (837ms)
pass RunTask(app1:build) (834ms)
pass RunTask(app1:deploy) (814ms)
pass RunTask(app2:deploy) (839ms)

Expected behavior

For the above example I am expecting:

[... skip to RunTasks]
pass RunTask(app2:build) (846ms)
pass RunTask(app2:deploy) (869ms)
pass RunTask(app1:build) (832ms)
pass RunTask(app1:deploy) (878ms)

Environment

Issue observed in Moon 1.31.0 (also earlier versions)
I am operating on windows 10

Additional context

It can be I am just misunderstanding what it means, in which case the documentation could be improved to clarify, or there is an issue here!

It doesn't happen automatically, you need to use the ^: target in task dependencies. Running everything by default is a bad idea.
