Rush • A new and improved way of building extensions

[shreyash]

As mentioned in the post you linked, Rush needs Java Development Kit (JDK) 8 to compile your extensions. You've Java Runtime Environment (JRE) 8. Download and install JDK 8 and try again.

[oseamiya]

-- It says i already have installed JDK , Downloaded from
https://www.oracle.com/java/technologies/javase/javase-jdk8-downloads.html

You should run below commands in CMD and show the result:

java -version
javac - version 

Also can you show the screenshot of Path environment variable?

[oseamiya]

After running the commands ,

I've installed it from PowerShell and In wiki of rush , it is said :

With PowerShell, you don't need to update the PATH environment variable manually, the script does it for you automatically.

What happens if you uninstall the already installed JDK and reinstall it?

[Kumaraswamy]

Well, I have faced the exact issues with the current version.
Sometimes I get it to work by -r flag.

[oseamiya]

I deleted Rush Files and JDK , then i reinstalled it ... And it is working charm now

Thankyou @shreyash and @vknow360 for your replies ...

[Know_About_IT]

@oseamiya Same issue for me, always rush build fails, even blank aix

[shreyash]

This shouldn't really happen unless:

• You don't have JDK installed on your system.
• JDK's bin directory isn't on your PATH environment variable.

If that's not case, can you try reinstalling JDK 8 like @oseamiya did?

[Know_About_IT]

@shreyash

If that's not case, can you try reinstalling JDK 8 like Sneha did?

Ok Sir, thanks for support

What kind of Command Prompt are you using?
Because I see in your documentation your Command Prompt is different than mine

And in your documentation what does cd mean?
does that mean "command"

How can I update rush to the latest version if it is available?

[shreyash]

The terminal that you're seeing the first post is VS Code's integrated terminal (w/ Git Bash).

@Salman_Dev

And in your documentation what does cd mean?
does that mean "command"

cd is a UNIX command used to change the current working directory in the terminal. You can find enough information about it on the internet.

@Salman_Dev

How can I update rush to the latest version if it is available?
