運行eclipse就提示 The Eclipse executable launcher was unable to locate its companion library. 解決方案

你試試把中文路徑換掉 不行的話參考 逝去的青春的博客：
Eclipse出現“The Eclipse executable launcher was unable to locate its companion shared library”錯誤的解決方法如下：
一、打開eclipse目錄下的配置文件eclipse.ini。
二、將--launcher.library和-startup下面的路徑都改為當前的正確路徑。 如我的eclipse的存放路徑由D:\Program Files\改為D:\，則將路徑里eclipse前的“Program Files\”去掉即可。
如果要在eclipse打開時顯示工作路徑對話框,則有兩種解決方法：
方法一、關閉Eclipse並打開eclipse的安裝目錄，依次打開以下目錄，configuration\.settings文件夾下有一個文件org.eclipse.ui.ide.prefs，用記事本打開，將下列紅色字符改為true即可：SHOW_WORKSPACE_SELECTION_DIALOG=true
方法二、設置方法如下：依次打開Window -> Preferences -> General -> Startup and Shutdown 。然后勾選Confirm exit when closing last window復選框即可。或者點擊Restore Defaults按鈕。 *********************************************************************************************************** 下面這個跟你的問題比較像：摘自kiwi's garden的博客 The Eclipse executable launcher was unable to locate its companion launcher jar的解決方法 To resolve this issue perform the following steps: Go to the installation location (for example, C:/Program Files/IBM/TeamConcert) Copy the eclipse.ini file to a backup file (such as eclipse.ini.bak). Edit the eclipse.ini file and remove these two lines: -startup plugins/org.eclipse.equinox.launcher_1.0.100.v20080509-1800.jar Start the Rational Team Concert client again.
大概就是說在安裝目錄里找到eclipse.ini 然后移除以下兩行: -startup plugins\org.eclipse.equinox.launcher_1.0.100.v20080509-1800.jar
