I can't run or export my mod

I'm sorry if there are any mistakes as I use a translation application. When I want to test my mod it gives an error. 

MCreator detected Gradle caches got corrupted. Don't worry, we can fix this for you, we just need to rebuild these caches. This action will not affect your files or workspaces, but after clearing the caches, build of every generator type and version will take a bit longer the first time. In some cases, clearing entire Gradle folder is needed to resolve Gradle errors.
