如何使用Java-Google Docs Api将文件上传到Google驱动器？

Question

Already I used older version of the API to upload files to Google docs but now the API version is revised, so I couldn't upload.

Previously I used these lines for authorization:

DocsService service = new DocsService("MyDocumentsListIntegration-v1");
    service.setUserCredentials(USERNAME, PASSWORD);

But now it is giving this error:

Exception in thread "main" java.lang.NoClassDefFoundError: javax/mail/MessagingException
    at sample.main(sample.java:15)
Caused by: java.lang.ClassNotFoundException: javax.mail.MessagingException
    at java.net.URLClassLoader$1.run(Unknown Source)
    at java.security.AccessController.doPrivileged(Native Method)
    at java.net.URLClassLoader.findClass(Unknown Source)

    at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
    at java.lang.ClassLoader.loadClass(Unknown Source)
    ... 1 more

Can anyone help me?

Answer 1

It seems like you are missing one of the external dependencies, mail.jar, which is part of Sun's JavaMail API.

Check this page for instructions on how to get it as well as all other external dependencies: https://developers.google.com/gdata/articles/java_client_lib

Check this link for a migration guide for the old GData api: http://code.google.com/p/gdata-java-client/wiki/MigratingToGoogleApiJavaClient

Hope this helps.
