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
