fedora20 Eclipse for JAVAEE 關於重起後沒法打開

個人環境是fedora 20,eclipse for ee 是2014年5月目前的最新版，且爲官網下載。出錯的情況以下：

解壓後能完美運行，重起後則報錯：Locking is not possible in the directory "/usr/eclipse/configuration/org.eclipse.osgi". A common reason is that the file system or Runtime Environment does not support file locking for that location. Please choose a different location, or disable file locking passing "-Dosgi.locking=none" as a VM argument.

各類百度方案均不能根治，好比提高工做空間權限，修改/usr/eclipse/configuration/org.eclipse.osgi的權限，都是當時能行，重起後又報錯。後來發現我fedora的登錄賬號ksisn不屬於sudoers管理組，也未設置過密碼。最後將ksisn提高到sudoers組中就不出錯了。linux新人勿噴。
