Eclipse内容辅助错误

Question

最近，我一直在使用Eclipse中的内容辅助方面遇到越来越多的问题。在我的一些项目中，我没有收到内容协助的建议，在其他项目中，我收到了部分或全部预期建议。通常不存在“错误”在Eclipse中，但这里是当我得到一个错误中的一个例子：

"Content Assist" did not complete normally. Please see the log for more information. Pb(324) The type android.support.v4.app.LoaderManager$LoaderCallbacks cannot be resolved. It is indirectly referenced from required .class files

我已经从类似的问题试过了各种建议（包括但不限于以下两个）没有运气。我甚至已经删除并重新安装eclipse，并重新创建没有任何Eclipse元数据或设置的项目。

• Eclipse Content Assist not working with Android
• Eclipse/Java code completion not working

任何帮助是极大的赞赏。

的Eclipse SDK 版本：3.7.2 版本ID：M20120208-0800

的Android开发工具包 版本：18.0.0.v201203301601-306762

Answer 1

我最终将ActionBarSherlock库升级到最新的4.1（http://actionbarsherlock.com/），它修复了我的eclipse问题。

Answer 2

试试这个

窗口>>首选项>> Java >> Editor >> Content Assist >>恢复默认值

窗口>>首>> >>的Java编辑器>>内容辅助>>高级>>恢复默认值

Answer 3

我有一个类似的问题与使用V4兼容库项目，当它被更新。尝试移除库上的项目依赖项，重新启动Eclipse，然后重新添加依赖项（我想认为这是我所做的解决此问题的方法，但如果这样做不起作用，我会尝试去考虑我可能做了什么）

Answer 4

我也有这个问题，Pb（324）消息。事实证明，阅读理解的信息足以解决问题。然而，我第一次做的是要叠加。没有好:)

在我的groovy项目中，依赖库不能通过自动完成自动显示。不知道为什么，我是这个新手。所以我手动添加它们。但我没有手动添加间接依赖项。错误消息指定导致问题的类。 我添加了对包含有问题的类和宾果游戏的jar的引用 - 没有更多的代码帮助错误。

具体：项目，属性，Java构建路径，库，添加外部JAR。然后我指向目录，gradle下载了lib。
