Repro steps

• ng generate library dd-ng-primitives --prefix=dd
• add interfaces with JSDoc. Sample:

/**
 * Container size.
 * @export
 * @interface Size
 */
export interface Size {
  /**
   * Container width into pixels.
   * @type {number}
   * @memberof Size
   */
  width: number;

  /**
   * Container height into pixels.
   * @type {number}
   * @memberof Size
   */
  height: number;
}

-- ng build --prod dd-ng-virtualized

Desired functionality

Library builded without errors.

Mention any other details that might be useful

Hi, those JSDocs are redundant and should be removed in order to get your library working.

Redundant JSDocs will cause the build to fail.

@alan-agius4, it is will be to work for a follow releases?

[alan-agius4]

@derkachdeveloper, I am not sure if I understand what you meant above. but, if you meant, if this is a bug that will be solved in the future. I don't know, it's a tsickle https://github.com/angular/tsickle/blob/d24b139b71a3f86bf25d6eecf4d4dcdad3b379e4/src/jsdoc.ts#L170-L178, and redundant JSDocs needs to be removed in order to get your build working.

I suggest you enable the no-redundant-jsdoc tslint rule. https://palantir.github.io/tslint/rules/no-redundant-jsdoc/

[alan-agius4]

Take a look at: angular/angular#19969

@alan-agius4 , thank you. Close issue.

[matheusdavidson]

My solution, in angular 7, was change my tsconfig.lib.json config,

from this:

"angularCompilerOptions": {
    "annotateForClosureCompiler": true
    ...
    ...
}

to this:

"angularCompilerOptions": {
    "annotateForClosureCompiler": false
    ...
    ...
}
