方法解析错误仍然存​​在，即使它们是在库项目中定义的

Question

我在eclipse中有两个项目。一个是我用SVN下载的java项目，并使用Maven来处理它的依赖项。我能够编译它，并按照我关注的说明将生成的jar文件添加到另一个Android项目。后者也使用了Maven。我有一堆错误;通过将编译器版本从1.5更改为1.6来处理大部分问题。 关于2种方法存在两个剩余错误，这些错误未在JAVA项目中实现。我编辑了该文件，并添加了该方法。但我在Android项目中的错误并没有消失。 android项目引用，并查看java项目中的其余方法和类。你能帮我解决这个问题吗？我该怎么办或检查一下？您需要哪些信息来提供帮助？

重新启动eclipse后，错误消失了。我之前尝试过重启，但似乎我不得不让eclipse在更长的时间内保持关闭状态。

现在，当我尝试运行它时，我在logcat中遇到以下异常错误：
