class file for com.google.errorprone.annotations.RestrictedInheritance not found

Just updated Google Places SDK from 3.3.0 to 3.4.0 which bumped play-services-base from 18.0.1 to 18.3.0, resulting in the following problems:

Can you please add the RestrictedInheritance annotation and checker to the error-prone artifacts? or hide the private annotation from the public API.

Workaround

Create a new file at src/main/java/com/google/errorprone/annotations/RestrictedInheritance.java in the module that uses play-services-base:

package com.google.errorprone.annotations;

/**
 * Workaround for <code>class file for com.google.errorprone.annotations.RestrictedInheritance not found</code>.
 *
 * <pre><code>
 * warning: Cannot find annotation method 'explanation()' in type 'RestrictedInheritance'

 * warning: Cannot find annotation method 'allowlistAnnotations()' in type 'RestrictedInheritance'
 * </code></pre>
 *
 * @see <a href="https://github.com/google/error-prone/issues/4335">Report</a>
 */
public @interface RestrictedInheritance {
	String explanation();
	String link();
	String allowedOnPath();
	Class<?>[] allowlistAnnotations();
}

Thanks for the report!

We may eventually finalize the annotation to and include it in error-prone-annotations, but until that happens I have filed an internal issue against the owners of play-services-base about hiding the annotation from the API [b/330519201].

Thanks for forwarding the issue internally!
