Redis – Azure Functions project using Visual Studio Code in java

I am trying to use VSCode to create azure function and deploy it to azure. I followed the official documentation as described,

https://learn.microsoft.com/en-us/azure/azure-functions/functions-create-first-function-vs-code?pivots=programming-language-java.

did everything as described in this document but got the error on pressing F5 upon reaching the section ‘Run the function locally‘. I tried few things by searching on internet but none of them work. I noticed there is an open issue on official github account reported way back in 2017

https://github.com/Microsoft/function-demo-java-on-azure/issues/3

That makes me wonder is this problem still exist?

Already spent lots of time on this but couldn’t make it to work. Any help is appreciated

          Environment:
          VS Code: v1.44.0
          jdk 11.0.3
          node v12.16.1
          maven v3.6.3

successfully installed the azure function core tools using the command, npm install -g azure-functions-core-tools@3

Here is complete error trace

    Turned out that the problem is with the incompatible java version. Currently azure functions support only JDK8 but I used JDK11. After switching to the right java version, the problem is solved.

    I encountered the same issue, the default pom.xml created with Azure Functions gives this error when using Java 11.

    I found that Azure has added support for Java 11 since 26th Oct 2021.

    https://azure.microsoft.com/en-in/updates/java-11-support-for-azure-functions-is-now-generally-available/

    But the default pom still comes with 1.8 support configurations.

    I used this https://learn.microsoft.com/en-us/azure/azure-functions/functions-reference-java?tabs=bash%2Cconsumption#java-versions as a reference and updated the pom.xml as below to make it compile and run in Java 11.

    <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <java.version>11</java.version>

    <azure.functions.java.library.version>1.3.1</azure.functions.java.library.version>
    <maven.compiler.source>11</maven.compiler.source>
