我正在android上构建一个应用程序，遇到了一个错误，在网上搜索时，发现了你在上面的帖子，并更改了eclipse.ini以增加xms和xmx参数，但这个错误仍然没有消失。
我在Mac OS上使用Eclipse IDE进行Android SDK 2.1的Java操作。请帮帮我，或者让我找一个可能知道的人。
顺便说一句，这个错误只在我添加外部jar文件（我的项目需要这个文件）时发生。下面是我的类路径中的外部jar文件列表。）
来自apache的httpclient-4.0.1.jar
来自apache的httpcore-4.0.1.jar
来自apache的commons-codec-1.3.jar
来自apache的commons-logging-1.1.1.jar
来自google的json_simple-1.1.jar
以下是完整的错误：

最佳答案
在r14中，它们改变了引用外部库的方式，这可能会导致此问题。您可以通过从文件夹树中删除链接的文件夹（名称中带有src）来解决此问题：
右击并选择“构建路径>从构建路径移除”
弹出窗口将打开。确保选中“同时取消文件夹与项目的链接”，然后接受它。
