ALTER SETTINGS CONFIGURATION does not support ExtraJvmParameters

[engalar]

Problem

ALTER SETTINGS CONFIGURATION does not support the ExtraJvmParameters key, which corresponds to the Extra JVM parameters field in Studio Pro under Settings → Configuration → Server tab.

Reproduction

./mxcli -p CarrefourAgent.mpr -c "ALTER SETTINGS CONFIGURATION 'Default' ExtraJvmParameters = '-Dhttps.proxyHost=127.0.0.1 -Dhttps.proxyPort=29758'"
# Error: unknown configuration setting: ExtraJvmParameters

Also tried JavaOpts — same error.

Use case

Setting HTTP/HTTPS proxy for JVM is a common requirement for:

• Routing AWS SDK calls through a local proxy
• Corporate network environments requiring proxy
• Debugging API traffic

Currently the only way to set this is manually in Studio Pro, which breaks the fully-automated CLI workflow.

Expected behavior

./mxcli -p app.mpr -c "ALTER SETTINGS CONFIGURATION 'Default' ExtraJvmParameters = '-Dhttps.proxyHost=127.0.0.1 -Dhttps.proxyPort=29758'"
# Should succeed and persist the value in the MPR

Environment

• mxcli: 0.1.0
• Mendix: 11.6.4

Issue Triage

Summary:
The ALTER SETTINGS CONFIGURATION command fails to recognize the ExtraJvmParameters setting, preventing users from setting JVM proxy options via mxcli.

Checklist (bug report):

• ✅ mxcli version: 0.1.0
• ✅ Mendix version: 11.6.4
• ✅ Scenario: CLI command to alter settings
• ✅ Expected output: Command succeeds and persists the value
• ✅ Experienced output: Error “unknown configuration setting: ExtraJvmParameters”
• ❌ AI bug report: No output from mxcli diag --bundle or session log provided

Missing information:
Could you please run mxcli diag --bundle (or at least share the session log) and attach the results? This will help us diagnose the issue more effectively. Thank you!
