Nx Plugin E2E Generator to Scaffold tmp Directory Outside the Workspace

[koliveira15]

Summary

The Nx Plugin e2e-project generator currently scaffolds a temporary workspace directory (tmp) inside the host Nx workspace root. This leads to collisions with Nx Cloud runs when e2e test suites execute Nx commands. The core Nx repo does not use this pattern for its own test workspaces; instead, it generates temporary workspaces outside the repository root.

Problem

The current template creates the tmp directory under the workspace root, which causes Nx Cloud runs and metrics to capture temporary runs. This conflicts with the strategy the Nx repo uses for its own internal e2e test workspaces.

Adding a process.env.NX_NO_CLOUD in start-local-registry.ts is not ideal as it can lead to unintended side effects with caching.

Proposal

Update the Nx Plugin e2e generator so that the temporary e2e workspace is created outside the workspace root. This aligns the plugin e2e test scaffolding with how the Nx repo manages its own e2e test workspaces and prevents unintended side effects.
