Can not run java azure function locally, created using maven archetype:generate given on microsoft site using mvn azure-functions:run, not showing error. Its simply freezing.

Followed every step and verified many times mentioned in below link:
https://docs.microsoft.com/en-us/azure/azure-functions/create-first-function-cli-java?tabs=bash%2Cazure-cli%2Cbrowser
Below is screenshot of cmd running mvn azure-functions:run command

I tried to run mvn azure-functions:run -X and its showing below and freezing:

I had the issue, too.
Steps to reproduce (at least in my case):

• windows, java 8, mvn 3.3.3
• mvn archetype:generate -DarchetypeGroupId=com.microsoft.azure -DarchetypeArtifactId=azure-functions-archetype -DarchetypeVersion=1.35 -DgroupId=com.bla.function -Dversion=0.1-SNAPSHOT -DartifactId=arch-function
  -> results in [INFO] BUILD SUCCESS
• cd arch-function
• mvn package
  -> results in [INFO] BUILD SUCCESS
• mvn azure-functions:run -X
  -> results on stopping at:
  [INFO] Azure Function App's staging directory found at: V:\V1420-Microservices\arch-function\target\azure-functions\arch-function-20210326092331413
  [DEBUG] Executing command: func

If I try to "cd" to the staging directory and call "func start"
then -> it works!

(...Maybe this is a workaround)

I tried to inspect the running process with the jconsole. The main thread is blocked at:

.... maybe this helps somehow

Maybe this is related to the maven plugin and not to the archetype

Thanks a lot luzuz! I am extremely thankful to you.it worked the way you mentioned. I was struggling since 2 days as I am new to azure functions.
Is it going to work fine like for all java azure functions httpTrigger,timeTrigger etc. And also will it work fine while publishing to azure ?

@Luzuz Thanks a lot for your comment.

@sarojbala123 Thanks for your report and really sorry for the trouble. We meet some compatibility issues with the latest function core tools. The issue has been addressed in microsoft/azure-maven-plugins#1367, will be shipped in functions maven plugin 1.10.0. Before the release, you may use core tools 3.0.3331 or previous version or invoke func host start in staging folder as a workaround.

I also tried running Spring boot azure function using TimeTrigger by following below steps:
Followed every step and verified many times mentioned in below link:
https://docs.microsoft.com/en-us/azure/developer/java/spring-framework/getting-started-with-spring-cloud-function-in-azure

instead of HttpTrigger I used TimeTrigger

Its showing a new error now as shown below: I have used local.setting.json properties as shown
