Hey everyone! so i was creating a file during runtime and then accessing it (File.readLines()) but it throws an error of file not found? Is it because we cannot read the file created during runtime? If so is there any work around happy to discuss

[Big Chungus]

Did you actually write the file? Just constructing File instance does not create a file

[Big Chungus]

Also this is not really kotlin specific

[Ansh Tyagi]

so right now what happens is there is a ProcessBuilder which creates a file at runtime and i just need to read some outputs of those file

[Ansh Tyagi]

i too feel its not kotlin specific but when i hardcode the file path it reads it

[Big Chungus]

Might be a race condition then. Check if the file exists before accessing it via File::exists

[Big Chungus]

Also check your file's canonicalPath to verify that it's pointing to where you expect

[Ansh Tyagi]

i even tried making Thread.sleep for a few sec but no outcome. File::exists show that this file does not exists but it does.

[Ansh Tyagi]

I’ll check once with the canonicalpath

[Big Chungus]

Most likely paths are resolving differently to what you expect

[Big Chungus]

This is likely due to processed running in different workingDirs and using relative paths

[Big Chungus]

To be honest this smells like bad architecture

[Big Chungus]

Easiest fix, convert file to absolute file before writing and passing it along

[Ansh Tyagi]

Great! altho i switched the working dirs to the project root. That solved my problem

this sounds like gradle, in which case
1. you cannot rely on a particular working directory within the build script, it depends on how Gradle was launched
2. you should use exec {} or an Exec task instead of ProcessBuilder
3. 😶
