我有一个关于eclipse IDE的问题,我不能打开我的工作空间中的任何文件;如果我尝试打开文件,eclipse将警告下面的错误对话框
"An error has occurred. See error log for more details. java.lang.NullPointerException"
我在workspace的. meta中查看. log文件,在文件中看到这样的段落:
!ENTRY org.eclipse.jface 4 2 2557-04-09 11:40:49.422
!MESSAGE Problems occurred when invoking code from plug-in: "org.eclipse.jface".

Eclipse
有一个bug:https://bugs.eclipse.org/bugs/show_bug.cgi?id=385680
您可以尝试重新启动
Eclipse
,它帮助了问题的原始海报。c7rzv4ha2#
最好通过单击 help >> check for updates 来更新Eclipse,也可以通过在命令提示符下输入命令 eclipse -clean 来启动Eclipse。
希望这对你有帮助。

我也遇到了这个错误。刚才我打开了新窗口,即窗口->新窗口在eclipse。然后,我关闭了我的旧窗口。这解决了我的问题。

嗨,那可能是项目的问题
选择项目并设置eclipse:
gopyfrb35#
退出eclipse后,我将.eclipse(在用户的主目录中)移到. eclipse.old(以防我可能必须撤消)。这个错误不再出现了,我的项目在重新启动eclipse后工作正常。
注意:我有一个简单的设置,这可能不是最好的环境与高级设置。
我张贴这作为一个单独的答案,因为以前列出的方法不适合我。

我遇到了同样的错误,但只是从git克隆的文件被分配给专有插件。我意识到,即使从git克隆了文件,我也需要创建一个新项目或在eclipse中导入一个项目,这解决了错误。

**这个解决方案也很好用!!**我在eclipse中也遇到了这个问题,只是在一些文件中,而不是在所有文件中。
当以下解决方案不起作用时
1.清洗后
1.打开新窗口后
解决方案:-
1.请从Eclipse工作区备份您的文件
1.从工作区中删除文件
1.创建具有相同名称的文件并保存备份文件中的代码
1.然后它开始正常工作!!
这是工作的罚款!!。你也可以试试这个。
