use java class with '$' symbol in the class name

I am trying to use the Google's Sheets Java API (https://developers.google.com/sheets/api/quickstart/java) directly in Matlab. One of the classes has a '$' symbol in its name. In Java it is accessed using dot notation as in:

GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder(
                HTTP_TRANSPORT, JSON_FACTORY, clientSecrets, SCOPES)
                .setDataStoreFactory(new FileDataStoreFactory(new java.io.File(TOKENS_DIRECTORY_PATH)))
                .setAccessType("offline")
                .build();

However when I am trying to import this class in Matlab with the dot notation

import com.google.api.client.googleapis.auth.oauth2.GoogleAuthorizationCodeFlow.Builder.* 
flow = GoogleAuthorizationCodeFlowBuilder.Builder(HTTP_TRANSPORT, jsonFactory, clientId, clientSecrets.toString, SCOPES);

I am gtting the error 'Unable to resolve the name GoogleAuthorizationCodeFlowBuilder.Builder.' methodsview('GoogleAuthorizationCodeFlow.Builder') results in

Error using methodsview (line 101)

No class GoogleAuthorizationCodeFlowBuilder.Builder can be located or no methods for class.

Looking into the jar I noticed the class name is actually GoogleAuthorizationCodeFlowBuilder$Builder. With '$' in the name, the methodsview works:

import com.google.api.client.googleapis.auth.oauth2.GoogleAuthorizationCodeFlow$Builder.* 

However can't use it because matlab complains about the '$' symbol in the code:

Is there a way to work around this? I am not very experienced using Java in Matlab, so maybe I am just overlooking something?

Thanks in advance!

Hi,

It seems that Builder is a nested class inside GoogleAuthorizationCodeFlow.($ denotes presence of inner class)

Try

import com.google.api.client.googleapis.auth.oauth2.GoogleAuthorizationCodeFlow.*;
flow = GoogleAuthorizationCodeFlowBuilder.Builder(HTTP_TRANSPORT, jsonFactory, clientId, clientSecrets.toString, SCOPES);

Hi,

thanks. Unfortunately it does not work either:

Methodsview does not recognise it with the dot notation either. However it does recognise the GoogleAuthorizationCodeFlowBuilder$Builder as previously:

Since import does seem to accept the $ in the class name, is there any way to assign an alias like in

import com.google.api.client.googleapis.auth.oauth2.GoogleAuthorizationCodeFlow$Builder.* 'as' FlowBuilder
