正常打开工作空间之后发现项目关闭了，然后要打开它就报错

The project description file (.project) for ‘xxx’ is missing. This file contains important information about the project. The project will not function properly until this file is restored.

解决方法：删除（不删除文件）之后重新导入。

配置方式 每个starter都有自己默认的配置，如果需要改变默认值，可以在其他地方配置来覆盖掉默认的值，覆盖默认的配置有多种方式，每种方式的优先级也不同，如果在多个地方配置则优先使用优先级高的值，其中命令行参数优先级最高, 其中大部分参数一般都配置在属性文件application.properties中，属性文件即可以覆盖starter中默认的值，也可以自定义值 在命令行行输入的参数 SPR...

其实修复办法很简单：将Myeclipse Package Explorer中打不开的项目删除掉，再重新导入即可。造成此问题的主要原因是Myeclipse中记录的项目位置发生了改变，造成Myeclipse找不到.project文件。我原来插入u盘后，磁盘盘符显示是J盘，这次插入后不知道什么原因盘符变成I盘了。Myeclipse中记录的项目地址依然为J盘，这就造成Myeclips...

其实修复办法很简单：将Myeclipse Package Explorer中打不开的项目删除掉（注意：一定不要为删除对话框中的Delete project contents on disk(cannot be undone)打上对勾(√)。点击OK,删除掉不能打开的项目。），再重新导入即可。造成此问题的主要原因是Myeclipse中记录的项目位置发生了改变，造成Myeclipse找不到.pro

1.前言 好久没动的项目，今天突击一个小功能，首先想到要更新下最近的其他开发提交的代码。没想到更新以后问题还没出现，因为现在工作空间是打开的状态的。等下午退出之后，在打开工作空间问题出现了，项目自动关闭了。，问题来了，双击打开的时候，报错。会弹框说什么.project的问题。我想今天就更新了下 svn库的代码，怎么会有这种情况呢？ 2.解决 带着一头雾水找问题，既然是.project的问题...

“经典动态规划问题过河卒代码实现”

资源下载链接为： https://pan.quark.cn/s/abbae039bf2a 在棋盘上，A点有一枚过河卒，目标是抵达B点。卒的移动方式仅限于向下或向右行进。然而，棋盘上存在一个对方的马（比如C点的马），马所在的点以及它能一步跳跃到达的所有点都属于对方马的控制范围。以C点的马为例，它能控制9个点（包括C点本身以及图示的P1至P8）。卒在行进过程中，不能经过对方马的任何控制点。
