今天早上打开MyEclipse时,自动关闭!弹出An error has occurred.See the log file错误提示!
很郁闷昨天启动和关闭还好着!!!打开几次依然报此错误,确定不是眼花了!
打开日志文件!找到当日错误文件内容:

网上找了下:
第一:金山升级修改了内存!(我金山昨天是升级了金山,但是那帖子是08年1月的。我想要是有这个bug,金山早改了。况且那个帖子也是个太监贴,没下文!不想费时间在金山的装卸载上)
第二:项目目录中有中文。(我项目路径中是有中文,但是我已经用了十几天了,没有事!今天出现了也不会是这个问题。)
第三:删除掉那个。Log文件(删除掉依然不起作用)
。。。。。。。。。。。。。。。还有一些乱七八糟的,就不说了!前面这三个网上常见!
解决:修改项目工作空间。
修改工作空间,以前打开myEclipse时知道怎么改!现在只有找配置文件了!
步骤:
MyEclipse 5.1.1 GA-----》Eclipse-----》configuration------》.settings----》org.eclipse.ui.ide.prefs文件
#Tue Jul 28 09:10:40 CST 2009
RECENT_WORKSPACES_PROTOCOL=2
MAX_RECENT_WORKSPACES=5
SHOW_WORKSPACE_SELECTION_DIALOG=false
eclipse.preferences.version=1
RECENT_WORKSPACES=D\:\\caodf,C\:\\Documents and Settings\\Administrator\\workspace
删除掉你以前的工作路径!保存!关闭!重启MyEclipse就好了!
