Question

我正在考虑使用eclipse中的“终端”来完成我的eclipse项目。它似乎作为Windows命令提示符。但是从终端，我无法获得java。当我尝试在终端中键入“java”时，我遇到了错误。

C:\Users\myName>java
'java' is not recognized as an internal or external command,
operable program or batch file.

当我从Windows命令提示符运行相同的“java”时，它正确地返回java值。

eclipse会出现什么问题？终端是否像普通的命令提示一样工作，否则需要在eclipse中以不同的方式配置命令提示符？

我的主要目的是，当我在eclipse IDE上工作时，我不想使用外部命令提示符。

由于我是eclipse IDE和终端的新手，建议我一个解决方案。感谢。

Answer 1

结合一些已经提到的解决方案，您可以按照以下方式实现。

您定义JAVA_HOME和PATH将其包含为系统变量
您在启动eclipse的同一会话中定义JAVA_HOME和PATH包含它作为环境变量（例如在CMD脚本中）
set JAVA_HOME=...<br> set PATH=%JAVA_HOME%\bin;%PATH%<br> exclipse.exe
您在终端的偏好设置中设置了JAVA_HOME和PATH Window -> Preferences -> Terminal -> Local Terminal -> Variables

其他解决方案仍有可能。

Answer 2

你在说哪个终端？您是否安装了TM Terminal插件或其他内容？

https://marketplace.eclipse.org/content/tm-terminal

Answer 3

如果你可以在windows终端中使用命令“java”，你只需按F11进行调试或按ctrl + F11运行程序而无需调试。
如果您无法在Windows终端中使用命令“java”，请检查环境变量。

正如我们从输出中看到的那样：

Windows PATH上没有java ...

目前的版本我在那里：

并且在此目录中有符号链接：
