fix(core): resolve input files for targets with defaultConfiguration (#34638) `nx show target inputs` returns empty results for any target with `defaultConfiguration` set because `HashPlanInspector.inspectTaskInputs()` keys results as `project:target:config` (e.g. `my-app:build:local`), but the lookup was using `project:target` — a guaranteed miss. ## Changes - **`packages/nx/src/command-line/show/target.ts`**: In `resolveInputFiles`, construct the plan lookup key using the explicitly passed `configuration` first, then fall back to the target's `defaultConfiguration`: ```ts const targetConfig = graph.nodes[projectName]?.data?.targets?.[targetName]; const effectiveConfig = configuration ?? targetConfig?.defaultConfiguration; const taskId = effectiveConfig ? `${projectName}:${targetName}:${effectiveConfig}` : `${projectName}:${targetName}`; ``` If the computed `taskId` is not found in the hash plan, an error is thrown instead of silently returning empty results. - **`showTargetInputsHandler`**: Now extracts the configuration from the target string (`project:target:config`) or the `-c`/`--configuration` flag and forwards it to `resolveInputFiles`. - **`ShowTargetInputsOptions`** (`command-object.ts`): Added `configuration?: string` so the type correctly reflects the prop. - **`packages/nx/src/command-line/show/target.spec.ts`**: Added tests covering: - Resolving input files when `defaultConfiguration` is set - Preferring an explicit `configuration` over `defaultConfiguration` - Throwing when the task ID is not found in the hash plan
