I am using CubeIDE, stm32l0xx_hal_def.h Apach-2.0
The contents of "stm32l0xx_hal_def." are shown in the attached photo.
It says something like "Apache-2.0".
This causes a compile error.
What should I do?

That's not a valid header file, no wonder it's giving error. Where did you get the project or how did you generate it? No doubt something went wrong in the process.
See here for the correct file:
Lots of error icons showing up on other headers, wouldn't be surprised if other files are wrong as well.
