Repro steps

Using an angular.json with multiple projects sharing the target name (ie, ‘serve’ and ‘build’ under the ‘architect’ node) will cause this error, even when specifying the project (ie. not a multiTarget). A recent change here caused this regression. It will give the error ‘Could not determine a single project for the ‘serve’ target.’ from within the call to getProjectNamesByTarget(), even though I have specified the project.

  "projects": {
    "stuff": {
      "architect": {
        "build": {

        }
      }
    },
    "morestuff": {
      "architect": {
        "build": {

The log given by the failure

Desired functionality

Ability to still use the same target names, ‘build’, ‘serve’, etc… across numerous projects in the same angular.json. A workaround is to use unique names.

err…ya, ok ill skip the repro unless you poke me again.

[alan-agius4]

The error Could not determine a single project for the 'serve' target. is indicated that it cannot locate a single project when you use build and run. Thus in order to use the these builders you’d need to provide the project name as an argument.

Ex;

$ ng serve morestuff
