When building a Vaadin 15 project with TypeScript views on Windows I am getting a lot of build warnings like "export 'default' (imported as '_typeof') was not found in '@babel/runtime/helpers/typeof'. I expect the build on Windows to pass without these warnings as it currently passes on Linux and OS X.
Steps to reproduce:
download a project from start.std.vaadin.com (Select the TypeScript + Spring Boot tech stack)
run mvn install vaadin:build-frontend on a Windows machine
see the build log

When building a Vaadin 15 project with TypeScript views on Windows I am getting a lot of build warnings like
"export 'default' (imported as '_typeof') was not found in '@babel/runtime/helpers/typeof'
. I expect the build on Windows to pass without these warnings as it currently passes on Linux and OS X.Steps to reproduce:
TypeScript + Spring Boot
tech stack)mvn install vaadin:build-frontend
