Runtime.getRuntime().exec doesn't work

[theapache64]

When running JAR directly, Runtime.getRuntime().exec("git") works, but running via the installed command, it doesn't work.

Exception in thread "main" java.io.IOException: Cannot run program "git": error=2, No such file or directory

Any idea?

What operating system? Is it a GUI app, or are you running through the CLI? Installed via npm install or via double-clickable desktop installer?

Are both running in same terminal environment? (in same terminal window)?

What operating system?

macOS

Is it a GUI app, or are you running through the CLI?

CLI

Installed via npm install or via double-clickable desktop installer?

Installed via sudo jdeploy install

Are both running in same terminal environment? (in same terminal window)?

Yes

You might want to check the environment (e.g. System.getenv()) to see what the difference is. Particularly in the PATH environment variable.

[theapache64]

Both are same. Confirm

UPDATE: The issue is not there in 1.022. I think its a regression came in ^3.0.0

[shannah]

Is it the same java version?

[theapache64]

Yes. Steps to reproduce

1. Create a new gradle based Kotlin project
2. Call Runtime.getRuntime.exec("git")
3. Export jar
4. Run jar through terminal java -jar my.jar (this will work)
5. Now install app using sudo jdeploy install and run the app from terminal

Those will be different versions of java.

Please post output of both system properties and env vars printed from inside the java app.
