包com.google.auth.http不存在

Question

因此，在尝试运行Google API项目的示例时，我一直遇到这些错误：

dungbui@cloudshell:~ (tiw-leader-project-355316)$ gradle run

/home/dungbui/src/main/java/Create.java:8: error: package com.google.auth.http does not exist

这是我的build.gradle文件：

这是我的create.java

     */
    public static String createSpreadsheet(String title) throws IOException {
        /* Load pre-authorized user credentials from the environment.
           TODO(developer) - See https://developers.google.com/identity for
            guides on implementing OAuth2 for your application. */
        GoogleCredentials credentials = GoogleCredentials.getApplicationDefault()
                .createScoped(Collections.singleton(SheetsScopes.SPREADSHEETS));
        HttpRequestInitializer requestInitializer = new HttpCredentialsAdapter(
                credentials);

        // Create the sheets API client
        Sheets service = new Sheets.Builder(new NetHttpTransport(),
                GsonFactory.getDefaultInstance(),
                requestInitializer)
                .setApplicationName("Sheets samples")
                .build();

        // Create new spreadsheet with a title
        Spreadsheet spreadsheet = new Spreadsheet()
                .setProperties(new SpreadsheetProperties()
                        .setTitle(title));
        spreadsheet = service.spreadsheets().create(spreadsheet)
                .setFields("spreadsheetId")
                .execute();
        // Prints the new spreadsheet id
        System.out.println("Spreadsheet ID: " + spreadsheet.getSpreadsheetId());
        return spreadsheet.getSpreadsheetId();
    }
}

，我从教程 https://develovelers.google.com/sheets/api/guides/create

这是我第一次尝试在Google API上尝试，有人可以告诉我如何解决此问题。

我认为您缺少所需的依赖性

尝试添加
实现'com.google.auth：google-auth-auth-library-oauth2-http：0.1.0' to your build.gradle

。 /main/java/create.java nate googlecredentials。
