[🐛 Bug]: SeleniumManager --offline mode ignores cached browser

[biski]

What happened?

I want to use SeleniumManager on a server without network access. I use the --offline mode, assuming that SeleniumManager will use the driver and browser from the cache folder.

For example:

 ./selenium-manager --browser chrome --browser-version 129 --language-binding java --trace

[2024-11-28T11:48:01.805Z INFO ] Browser path: /home/wojciech/.cache/selenium/chrome/linux64/129.0.6668.100/chrome

In this case, the browser path is correctly determined and points to the browser located in the cache.
However, when I add the --offline parameter, SeleniumManager incorrectly points to the default Chrome installation with the wrong version.

./selenium-manager --browser chrome --browser-version 129 --language-binding java --trace --offline

Could you please confirm if I understand the behavior of this parameter correctly? At the moment, it seems to me like a bug in SeleniumManager.

How can we reproduce the issue?

./selenium-manager --browser chrome --browser-version 129 --language-binding java --trace     
./selenium-manager --browser chrome --browser-version 129 --language-binding java --trace --offline            

Steps to reproduce:

1. Use SeleniumManager to download the browser in a specific version.
2. Use SeleniumManager in offline mode (--offline).

When using the --offline flag, Selenium Manager will use the local browser. Your case is indeed a bit different since you are also specifying a browser version, but in the current implementation, the offline flag prevails:

[2024-11-28T11:52:10.209Z DEBUG] Offline flag set, but also asked not to avoid browser downloads. Honouring offline flag

So, I believe you can simply avoid the --offline flag since Selenium Manager will always use the browser from the cache if it exists.

@bonigarcia Unfortunately, I can't use it without --offline flag because, on a server without network access, I receive the following error:

./selenium-manager --browser chrome --browser-version 131.0 --language-binding java
[2025-01-09T13:35:13.763Z ERROR] error sending request for url (https://googlechromelabs.github.io/chrome-for-testing/known-good-versions-with-downloads.json)

Ultimately, I would like to use SeleniumManager directly from Java to easily update browsers to the latest versions on multiple servers. For servers without access to external networks, I would like to manually upload browsers to the cache directory.
Could something be done about this?
