从 Luna 更新到 Mars 后无法打开 Eclipse IDE

Question

我将 eclipse Luna 更新到 Mars。我所做的是...

将火星 url 添加到 Window > Preferences > Install/Update > Available Software Sites
Help > Check for Updates
按照向导的指示进行操作
安装成功，弹出窗口显示我必须重新打开此应用程序(Eclipse)

现在，当我尝试打开 eclipse 时，会显示一条弹出消息。它说 "Can not open this application" 而没有其他任何信息。

好像更新成功了，不知道是哪里出了问题。我该如何解决或获得有关这种情况的一些线索？谢谢

仅供参考，我附上我的 eclipse.ini 和 java -version 的结果。

这是 ini 文件

-startup
../../../plugins/org.eclipse.equinox.launcher_1.3.100.v20150511-1540.jar
--launcher.library
../../../plugins/org.eclipse.equinox.launcher.cocoa.macosx.x86_64_1.1.300.v20150602-1417

我的版本是...

java version "1.8.0_40"
Java(TM) SE Runtime Environment (build 1.8.0_40-b27)
Java HotSpot(TM) 64-Bit Server VM (build 25.40-b25, mixed mode)

来自What's New in Mars：

For Mars (4.5), the Eclipse SDK for OS X is now distributed in a more standard "Mac App" format, instead of the "directory format" we have used in the past.

CAUTION: Current Mac users can not use "update" to Mars. In fact, doing so will break your installation! You need to start with a fresh download.

In the event that you updated before reading this, and have ended up with a broken installation, see Issues related to Mac App installations for the steps to recover your installation, after getting a fresh download.

因此您需要重新安装（您的工作区应该没问题）。
