If you are using Groovy, it's likely that you unintentionally added the `private` modifier to a property declaration:

```groovy
@InputFile
RegularFileProperty inputFile // this is a public property

@InputFile
private RegularFileProperty inputFile // this is a field, remove the `private` modifier
```
