Make sure you cd - change directory to the generated extension directory and then run rush build to compile your extension

[BNJ_nds]

I cant understand what you say.
Can you please explain me?

[iamwsumit (Sumit Kumar)]

You have to run the build command in extension folder directory. At what path you’re running the command?

[BNJ_nds]

Can you explain in a video please

[BNJ_nds]

I am running command at extension folder directory but its show same error

[BNJ_nds]

I having a new problem

[iamwsumit (Sumit Kumar)]

Search it in the rush topic. This problem is posted a lot of times there.

Rush • A new and improved way of building extensions

Check that you have: JDK installed and correctly set up. No whitespace in your extension’s base directory’s path.

Have you added the JDK path in your environment variable? Run echo %PATH% command in your CMD and post the output here.

Rush • A new and improved way of building extensions

Such abrupt failure of the build usually happens when Rush fails to invoke the Java compiler (javac). There could be many reasons behind this, but the two I can currently think of are: You don’t have JDK (Java Development Kit) installed, or javac is not on the system path variable; quite unusual, but may happen. Can both of you try running javac in the terminal? If you get an error saying command/program not found, you might need to install JDK 8, or add javac to your system’s path variable. …

I cant understand where is the problem in Environment variables.

[Xoma (Kumaraswamy)]

You are probably missing a path to the Java Bin directory and home.

[BNJ_nds]

Which Path can you say

[Xoma (Kumaraswamy)]

Changing anyone of the path is okay, can you try running java -version in terminal (cmd)?

Can both of you try running javac in the terminal? If you get an error saying command/program not found, you might need to install JDK 8, or add javac to your system’s path variable.

Can you follow this post to run the command javac -version

[BNJ_nds]

[Xoma (Kumaraswamy)]

That is the problem, you have set up Java but not the compiler.

[BNJ_nds]

How to setup this can you say

[Xoma (Kumaraswamy)]

What I can see from your previous screenshots is that you have not added the java path.

Follow the second example here (setting up javac)

[BNJ_nds]

Is this right

[Xoma (Kumaraswamy)]

Yes, try compiling the extension. rush build
