"错误:无法确定所选JDK中的Java VM可执行文件"的原因是什么？

Question

我正在使用IntelliJ IDEA 13.1.4并尝试了最新版本14.

运行SBT我收到以下错误:

Error:Cannot determine Java VM executable in selected JDK

我在我的机器和PATH上安装了JDK 1.7.

在日志中(~/Library/Logs/IntelliJIdea14/idea.log在MacOS上),有以下堆栈跟踪:

这可能是什么原因？

Answer 1

您应该能够通过设置jdk而不是打开/导入项目对话框来设置它.

在欢迎屏幕上,转到Configure -> Project defaults -> Project structure并添加jdk.

打开sbt项目应该可以正常工作.

从这里找到解决方案

Answer 2

设置JDK的另一种方法是从您当前的模块/项目设置(对于您当前的项目)

匹克Open Module Settings从项目的上下文菜单(或默认按F4键),
然后从左侧选项卡选择Project和正确的点Project SDK上下拉.

Answer 3

问题通常是由".idea/sbt.xml"中的错误JDK版本引起的,例如:

<option name="jdk" value="1.7" />

更改Project SDK时,此选项不会相应更新,请参阅SCL-10085.如果您通常配置了其他JDK(在我的示例中为1.7),则不会发生错误,但Project SDK将以静默方式进行更改.否则,会发生此错误.

通过手动将".idea/sbt.xml"中的值编辑为正确的JDK版本,可以轻松解决该问题.

Answer 4

当您尝试在"SBT任务"中执行刷新时也会发生相同的错误.

打开

Preferences -> Language & Frameworks -> Scala Compiler Server

打开

Run compile server (in external build mode)

刷新完项目后,再次将其关闭以在编辑器中更改代码时启用hotswapping.

Answer 5

我不得不打开 Settings -> Language & Frameworks -> Scala Compiler Server

然后在那里设置 JVM SDK，即<No SDK>.

这是在Project Structure -> Project.

请参阅此处的屏幕截图。
