Why do I need to download the JetBrains client every time I start a remote development connection?
已回答
I deployed a remote development environment on a debian 12.8 linux server and used gateway access. However, every time I start remote development, the jetbrains client is downloaded locally. Even if I shut down the current service, I still need to download it when I reopen it after a few minutes.

Hello,
The issue you're experiencing with the JetBrains client downloading repeatedly during remote development could stem from how the IDE handles the client binaries for remote execution. Here's a breakdown of potential causes and their resolutions:
1. Client Binary Not Persisting Locally
The JetBrains client binaries might not be persisting locally due to:
Insufficient permissions for the IDE to write files to the local directory.
The directory where binaries are stored is cleaned up or temporary.
Resolution:
Check the default directory where the JetBrains Gateway stores client binaries. On most systems, it should be in a hidden directory like ~/.cache/JetBrains/ or similar.
Ensure this directory has write permissions for your user.
Confirm that no system cleanup processes or scripts (e.g., tmpwatch) are removing files from this directory.
bash
ls -la ~/.cache/JetBrains/
Adjust permissions if necessary:
bash
chmod -R u+w ~/.cache/JetBrains/
2. Network Configuration or Proxy Issues
If you're accessing the remote server via a gateway, connectivity interruptions might cause the JetBrains Gateway to reinitialize and redownload the client.
Resolution:
Verify stable and persistent network access to the gateway.
Ensure that there are no proxy configurations interfering with file persistence or download.
3. Server Configuration
The server-side setup might force the client to refresh binaries if the installed IDE version does not match the one requested by the client.
Resolution:
Update the IDE version on the remote server to match the client version.
Use JetBrains Gateway to manually specify a version if needed.
4. Temporary Session by Default
By default, JetBrains Gateway may be starting a temporary session, causing the client to redownload the binaries each time you start a session.
Resolution:
Ensure you configure a permanent workspace instead of a temporary session. You can do this by explicitly linking your remote project to a local persistent folder.
5. IDE Version Mismatch
If the local client and the remote IDE versions are mismatched, the client might trigger a redownload.
Resolution:
Check the installed JetBrains Gateway and IDE versions locally and on the server.
Update the server-side IDE to match the Gateway client’s expected version.
Debugging Steps
Run the following commands to debug and ensure configurations are persistent:
Inspect Logs: Check logs to identify why the client binaries are re-downloading:
bash
Copy code
tail -f ~/.cache/JetBrains/JetBrainsGateway/logs/*.log
Monitor Files: Observe changes in the JetBrains cache directory:
bash
Copy code
watch -n 1 'ls -lh ~/.cache/JetBrains/'
If none of these resolve the issue, consider contacting JetBrains support with the logs for further assistance.

The client version is nailed to the backend IDE version. If you are using exactly the same IDE build to open all your projects — it should be reused until you update the remote IDE.
There is a possibility that something corrupts the client, such as antivirus software, and this triggers the redownload.
