The project was generated differently than before despite using forge src 1448 and the same commands each time.

You guys have any advice on what to do or check? I've been trying everything I can think of to fix this and it hasn't worked.

When I generated my latest project's workspace, the default minecraft run configuration was not available and the folder structure of the workspace was different. I haven't found anything like it on the internet.

1. create folder for workspace

2. extract contents of forge src zip into workspace folder

3. run "gradlew setupDecompWorkspace" and "gradlew idea" in workspace folder

Note: step 3 does not create the same folders and files as it did in the setups prior to the issue

4. open new project in idea, point idea at build.gradle

Note 2: the project loads properly, but there is no "Run Client" or "Run Server" run configurations

EDIT!: I'm an idiot, this is stupid.

Apparently I forgot to edit the build.gradlew with that "idea" code snippet. Whoops!
