Eclipse 更新失败并显示 "There were no installable units selected when the plan was computed."

Question

我在我的旧笔记本电脑上安装了 Eclipse。我正在购买一台新笔记本电脑，我将 Eclipse 树和我的工作区复制到了新笔记本电脑上。大多数东西似乎都可以在新笔记本电脑上运行，但今天当我看到插件更新时我注意到了。我尝试在新旧笔记本电脑上进行更新。旧笔记本电脑上的更新进展顺利，但新笔记本电脑上的更新尝试失败，并显示“计算计划时没有选择可安装的单元。”

这是与该尝试相对应的日志文件摘录:

Answer 1

我解决了这个问题。这是“Windows 7/程序文件”问题。您无法将STS或Eclipse安装到“Program Files”中，因为它需要写入应用程序目录，并且通常不能以管理员权限运行。

我希望这不会导致如此迟钝的症状。您可能认为它至少会报告“无法写入应用程序目录”之类的信息。
