Question

I try to use Google Calendar API Java library, and copy this code from example:

CalendarService myService = new CalendarService("abc");
try {
    myService.setUserCredentials("ав[e-mail]", "1111223");
} catch (AuthenticationException e) {
    // TODO Auto-generated catch block

}

I downloaded library from source: gdata-client-1.0, gdata-calendar-2.0, but I got errors:

Exception in thread "main" java.lang.NoClassDefFoundError: com/google/common/collect/Maps
    at com.google.gdata.wireformats.AltRegistry.<init>(AltRegistry.java:118)

    at java.lang.ClassLoader.loadClass(Unknown Source)
    ... 4 more

Where can I do mistake?

Answer 1

Caused by: java.lang.ClassNotFoundException: com.google.common.collect.Maps

The mentioned class is not found in the runtime classpath. The mentioned class is part of Guava. So, if you download and put it in the runtime classpath as well, then this error should disappear.
