@Anonymous azure function supports java 11, but you need function v3 for that:

@Anonymous To get the connection string , go to the azure portal, navigate to the cosmos db resource, go to keys and copy the primary string as shown below:

Then you can put the value in local.settings.json as key value pair: "settingsName" : "settingsValue."

Please refer to functions-run-local

functions-bindings-cosmosdb-v2-output - For cosmosDB output binding.

Let me know if this helps.

Hi i am able to work for JDK 11 by making below changes :
<property>
<name>FUNCTIONS_EXTENSION_VERSION</name>
<value>~3</value>
</property>

and

<runtime>

<os>windows</os>
<javaVersion>11</javaVersion>

But when i am giving in host.json version as 3 it is failing with below error
{
"version": "3.0",
"extensionBundle": {
"id": "Microsoft.Azure.Functions.ExtensionBundle",
"version": "[1.*, 3.0.0)"
}
}
But as per the articles we should make keep it 3.x

@Anonymous Could you please share the error/exception you are encountering?

'3.0' is an invalid value for host.json 'version' property. We recommend you set the 'version' property to '2.0'. This does not correspond to the function runtime version, only to the schema version of the host.json file. See https://aka.ms/functions-hostjson for more information on this configuration file.
[ERROR]
[ERROR] Failed to run Azure Functions. Please checkout console output

Hello @Anonymous It is mentioned in the document https://aka.ms/functions-hostjson that

"version": "2.0" is still the valid schema for Azure Functions v3.

However, you have already updated the FUNCTIONS_EXTENSION_VERSION correctly in the configuration.
