描述

We have the following two files in the package:

m.ts

export interface Foo {}

export function f(foo: Foo): void {
}

index.ts

export {f} from 'm';
export type * from 'm';

Actual result:

While linting this code the plugin prints the following error for index.ts:

Multiple exports of name 'f' import/export

Expected result:

I don't expect the error to be thrown for the above case as the second expression in index.ts exports types, so there should be no duplicates.

Plugin version: 2.31.0

研究方向
Investigate the rule 'import/export' in the eslint plugin import source code. Check the implementation of how exports are compared, specifically the handling of `export type *`. The issue indicates that type only exports are not being filtered out when checking for duplicate exports. Likely the fix involves checking whether an export is a type export and excluding it from the duplicate check. Refer to the file that implements the rule, possibly `src/rules/export.js` or similar. Also consider linked issues or PRs that might address similar problems.
