Question

我尝试使用Google Calendar API Java库，并从示例中复制此代码：

CalendarService myService = new CalendarService("abc");
try {
    myService.setUserCredentials("авaea@gmail.com", "1111223");
} catch (AuthenticationException e) {
    // TODO Auto-generated catch block

}

我从源代码下载了库：gdata-client-1.0，gdata-calendar-2.0，但是我收到了错误：

Exception in thread "main" java.lang.NoClassDefFoundError: com/google/common/collect/Maps
    at com.google.gdata.wireformats.AltRegistry.<init>(AltRegistry.java:118)
    at com.google.gdata.wireformats.AltRegistry.<init>(AltRegistry.java:100)

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

我哪里可以搞错？

Answer 1

引起：java.lang.ClassNotFoundException：com.google.common.collect.Maps

在运行时类路径中找不到提到的类。提到的课程是part的Guava。因此，如果您下载并将其放入运行时类路径中，则此错误应该消失。
