tsc command not found

[mueller-jens]

Hi I try to use jsweet-maven-plugin version 3.0.0-RC1 to create javascript Classes from my backend API classes. I download node and npm using the frontend-maven-plugin which works fine so far. But when i try to use the transpiler I get the error message that the tsc.cmd is not found. So i guess the tsc is not installed correctly. What can cause this error?

My pom looks like:

<build>
	<plugins>
		<plugin>
			<groupId>com.github.eirslett</groupId>
			<artifactId>frontend-maven-plugin</artifactId>
			<!-- Use the latest released version: https://repo1.maven.org/maven2/com/github/eirslett/frontend-maven-plugin/ -->

</build>

I get the error message:

Cannot run program "<user_home>.jsweet-node_modules\tsc.cmd" (in directory "D:\tools\eclipse-workspace\jsweet-test\target\ts"): CreateProcess error=2, Das System kann die angegebene Datei nicht finden
If I look into the directory <user_home>.jsweet-node_modules\ i can't see the tsc.cmd.
Is there any way to configure the path to tsc.cmd?

Hello.
I can't imagine it doesn't work with 2 drives :) but did you try putting all in C: ?

[mueller-jens]

Hallo @lgrignon, I will give it a try, but i don't think the result changes. I will come back to you with the test results as

[lgrignon]

Oh, did you mean that the tsc.cmd can be found elsewhere in your:
<user_home>.jsweet-node_modules\
?

Could you please tell me where it's located?

[mueller-jens]

Yes that is what i mean. It is not installed, if i install it manually using node it is installed in my ${project.basedir}/node_modules/.bin folder

[lgrignon]

JSweet should install it automatically. Could you please try deleting your <user_home>.jsweet-node_modules\ and check if there is some error message in automatic TS installation when you launch your mvn jsweet

[mueller-jens]

I have tried it again and now it was installed, but the tsc.cmd is located in the folder <user_home>\.jsweet-node_modules\node_modules\.bin\. Not directly in .jsweet-node_modules

[mueller-jens]

So i tried once more with newer npm and node version

<nodeVersion>v12.16.1</nodeVersion>
<npmVersion>6.14.4</npmVersion>

and this looks like it works with this setup

[lgrignon]

JSweet tries different locations to find tsc.cmd.
Does it find at your location?

If it works please close issue

[mueller-jens]

It doesn't find it in the .bin folder. But looks like the installation has changed in the last version.

Thanks for your support

Oh, perfect. Enjoy using JSweet :)
