• After automatically installing JDTLS, you need to manually add the environment variables. #7321: After automatically installing JDTLS, you need to manually add the environment variables.

Feel free to ignore if none of these address your specific case.

I ran into the exact same jdtls timeout issue a while back. After some digging, it seemed like network problems were interrupting the download.
Quick fix I used:

• Grab the latest jdtls snapshot manually: https://www.eclipse.org/downloads/download.php?file=/jdtls/snapshots/jdt-language-server-latest.tar.gz
• Make sure the folder exists: mkdir -p ~/.local/share/opencode/bin/jdtls
• Unpack it: tar -xzf jdt-language-server-latest.tar.gz -C ~/.local/share/opencode/bin/jdtls
• Double-check: Look for the org.eclipse.equinox.launcher_*.jar in ~/.local/share/opencode/bin/jdtls/plugins/.

uninstall opencode and re-install, set HTTP_PROXY/HTTPS_PROXY, it seems ok now
