Manually removing the file (as the current user that also ran the 'sbt new' command) is no problem. Is the template trying to delete the file while it is still 'in use'?

I have the same problem but only if I run it via sbt, but if you run g8 directly no error occurs:

g8 playframework/play-scala-seed.g8

I have the same on sbt

The same problem. I download Cmder and run sbt new <g8 template> successfully.

It throws an error!!!!!!!!

Nov 08 '18 09:11 ghost

Same problem here. Can't get it to work even when running g8 directly.

Why does this problem arise, and can anyone solve it？

Despite this really noisy error, the command (mostly) succeeds and the app will still build and run.

I try to delete the folder manually, but this error still raise.

One of the workarounds is to not use cmd altogether, go to intellij > create new project > select scala > lightbend project > from the list of templates select the appropriate one e.g. scala play seed (be sure to be connected to internet for this step) > there you go Now from cmd navigate to your project directory and run the following magical command sbt run You can browse the app on localhost:9000

@xiongdahu thanks! running cmd as Administrator solved the issue.

During installation before final stept close the handle to this .gitignore file using any windows special instrument, for example https://docs.microsoft.com/en-us/sysinternals/downloads/process-explorer
