android - Eclipse中的间歇性RequestFactory错误

Question

我已经在 AppEngine 连接的 Android 项目中成功使用 RequestFactory 好几个月了。不过，有时我在将 RequestFactory 子类化的文件中遇到问题

public interface MyRequestFactory extends RequestFactory {
    ...
}

Eclipse 在“public interface...”这一行给了我一个红色的 X，我得到的错误如下所示。 (请注意，这不是运行时，它只是在我编辑时出现在 Eclipse 窗口中)

奇怪的是，我通常可以做一些项目->清理并编辑代码几次，从不做任何实际的代码更改，然后“保存”，问题总是会消失。不过这次它卡住了。

有什么想法吗？

Answer 1

这是一个已知的 Eclipse 错误。我找到的唯一解决方案是重新启动 Eclipse。有时我必须在没有注释的情况下编译然后重新启动。
