fix(task): resolve project tasks in run blocks using TaskLoadContext #6614

jdx · 2025-10-09T10:37:54Z

Summary

Fixes project tasks not being resolved when called from root task run blocks
Creates proper TaskLoadContext from task specs to ensure all necessary project tasks are loaded
Adds comprehensive e2e test to prevent regression

Problem

When a task's run block referenced project tasks (e.g., { task = "//projects/backend:hello" }),
those tasks were not being loaded properly, causing "task not found" errors. This occurred even
though the same tasks worked correctly when referenced via depends.

Root Cause

The inject_and_wait function was calling config.tasks_with_aliases(), which uses a default
TaskLoadContext with load_all: false and empty path_hints. This context won't load tasks
from project subdirectories in monorepo mode.

Solution

Modified inject_and_wait to:

Create a TaskLoadContext from the task specs being injected
Use config.tasks_with_context(Some(&ctx)) instead of config.tasks_with_aliases()
Manually build the tasks_map with aliases (duplicating the logic from tasks_with_aliases())

This ensures that when a task references project tasks in its run block, those project
directories are included in the TaskLoadContext path hints, causing their tasks to be loaded.

Test plan

New e2e test test_task_monorepo_run_project_tasks passes
Tests 3 scenarios:
- Calling single project task from root task run block
- Calling project task via depends (existing functionality)
- Calling multiple project tasks from root task run block
Existing monorepo tests pass (test_task_monorepo_dependencies, test_task_run_depends)
Lint checks pass

Fixes: #6615

Note

Ensure project tasks referenced in run blocks are resolved using TaskLoadContext; add e2e coverage for monorepo task invocation.

CLI/Tasks:
- Update inject_and_wait in src/cli/run.rs to construct a TaskLoadContext from run-block specs and use config.tasks_with_context(...), then rebuild alias map to resolve tasks (including monorepo project tasks).
- Import TaskLoadContext to support context-aware task loading.
E2E Tests:
- Add e2e/tasks/test_task_monorepo_run_project_tasks validating:
  - Root run-block invoking //projects/backend:hello.
  - Dependency-based invocation from root.
  - Multiple project tasks in a run block (backend and frontend).

When a task's run block referenced project tasks (e.g., `{ task = "//projects/backend:hello" }`), those tasks were not being loaded properly, causing "task not found" errors. The root cause was that `inject_and_wait` was calling `config.tasks_with_aliases()`, which uses a default `TaskLoadContext` with `load_all: false` and empty `path_hints`. This context won't load tasks from project subdirectories in monorepo mode. The fix creates a proper `TaskLoadContext` from the task specs being injected, ensuring that all necessary project tasks are loaded before attempting to resolve and execute them.

src/cli/run.rs

+        let ctx = TaskLoadContext::from_patterns(specs.iter().map(|s| {
+            let (name, _) = split_task_spec(s);
+            name
+        }));


[nitpick] The anonymous closure is simple enough to be written inline without the intermediate variable assignment. Consider: TaskLoadContext::from_patterns(specs.iter().map(|s| split_task_spec(s).0))

Suggested change

let ctx = TaskLoadContext::from_patterns(specs.iter().map(|s| {

let (name, _) = split_task_spec(s);

name

}));

let ctx = TaskLoadContext::from_patterns(specs.iter().map(|s| split_task_spec(s).0));

+                    .collect::<Vec<_>>()


The intermediate collect::<Vec<_>>() on line 1241 is unnecessary and creates an extra allocation. Remove it to allow the iterator chain to be processed directly by the final collect().

Suggested change

.collect::<Vec<_>>()

Bug: Owned Task Iteration Dereferencing Error

The tasks_map now holds owned Task values, making t an owned Task in the iteration. Attempting to dereference t with (*t).clone() is incorrect for an owned value, leading to a compilation error.
