Repro Code

classTest{setvalue(val:string){// ...}getvalue():string{return'test';}}

ESLint Config

module.exports={"rules":{"@typescript-eslint/class-literal-property-style":"error"}}

tsconfig

{"compilerOptions": {"strictNullChecks":true,"experimentalDecorators":true  }}

Expected Result

Should be no errors because the setter exists

Actual Result

Error:Literals should be exposed using readonly fields.

Auto-fix:

class Test {  set value(val: string) {    // ...  }  readonly value = 'test';}

Then TypeScript error:
Duplicate identifier 'value'
