Bug: yarn build react/index,react-dom/index --type=UMD，It was emptied

[Topthinking]

Works for me:

$ rm -rf build

$ yarn build react/index,react-dom/index --type=UMD
# node ./scripts/rollup/build.js react/index,react-dom/index --type=UMD

I'm going to close this issue because I don't think we have the bandwidth to trouble shoot build issues like this via GitHub. For some reason, the command you're running isn't matching any of our build targets and it should be. Maybe something about your Editor or OS?

check your JDK

This is an upper level issue. powerShell changes the comma to a space when it is parsed (this is also clearly visible in your demo). This can be avoided by using other terminals such as Git Bash.
