What are the requirements for gradle.kts generated by spring initializr? - kotlin

Question

I modified the build.gradle file of the newly created gradle project named build.gradle.kts, and then copied the build.gradle.kts content of the demo project generated by spring initializr, and then build, this file reported a lot of errors, but spring initializr project can be built correctly.
The two build.gradle.kts are exactly the same. What's wrong?
