适用于 Java 的 Eclipse 和 Google API 客户端库

Question

我想使用 google 提供的客户端库来访问他们的 API。我已经按照他们网站上的几条说明来设置我的 Eclipse 并使用该库，但我不能。

我编写了一个类似于 Google-tasks-sample 的代码，每次我尝试运行它时，Eclipse 都会冻结，几秒钟后就会崩溃。 控制台输出：

[2012-01-07 12:30:22 - AdsenseNotify] Dx warning: Ignoring InnerClasses attribute for an anonymous inner class
(org.apache.commons.logging.LogFactory$2) that doesn't come with an
associated EnclosingMethod attribute. This class was probably produced by a
compiler that did not target the modern .class file format. The recommended
solution is to recompile the class from source, using an up-to-date compiler
and without specifying any "-target" type options. The consequence of ignoring
this warning is that reflective operations on this class will incorrectly
indicate that it is *not* an inner class.

它还给出了一个带有“GC限制开销”的错误对话框，之后我被迫关闭工作台。

我正在使用日食。已经安装了所需的插件。 我下载了谷歌库并将罐子添加到我的项目>构建路径>外部罐子中，但错误仍然存​​在。
