Install Azure functions core tools using
npm i -g azure-functions-core-tools@coreNavigate to VSCode Java Debug extension Jenkins server, and use your GitHub account to log in. When everything works fine, download the extension vsix file.
If the downloaded file is renamed to zip (for example when you download it from Microsoft Edge browser), you need to rename it back to
vscode-java-debug-0.1.0.vsix
Launch Visual Studio Code, press F1 and then type >Extensions: Install from VSIX in the command input box (the right-angle-bracket > is in the input box by default, so you don't need to duplicate it); then press Enter, and a dialog will be popped up, you need to choose the vscode-java-debug-0.1.0.vsix which is the one you just downloaded. After it is installed, Visual Studio Code will ask you to reload the whole window, and just do it.
Clone the azure-functions-java-worker repository to your local folder using:
git clone https://github.com/Azure/azure-functions-java-worker.gitEnter the repository you just cloned by executing:
cd azure-functions-java-workerAnd install it locally by running:
mvn clean installDo similar things for other two packages: azure-maven-archetypes and azure-maven-plugins. You are required to clone all the packages in your working directory (which should just be the parent folder of azure-functions-java-worker).
git clone https://github.com/Microsoft/azure-maven-archetypes.git
cd azure-maven-archetypes
mvn clean install
cd ../
git clone https://github.com/Microsoft/azure-maven-plugins.git
cd azure-maven-plugins
mvn clean installAdd a new environment variable called JAVA_OPTS, and set its value to -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=5005 (don't miss the leading dash there).
Create a new storage account by executing (The UniqueID is just used to make sure your account name doesn't conflict with others, for example you can use the "current date & time", or "your alias + sequence number"; make sure the total length of the names are not exceeding 24 characters, and make sure you only use lower-case letters or numbers):
az group create -n BoothAzFunc<UniqueID> -l westus
az storage account create -n boothazfunc<UniqueID> -g BoothAzFunc<UniqueID> -l westus --sku Standard_LRSFinally to get the storage connection string which will be used in the future:
az storage account show-connection-string -n boothazfunc<UniqueID> -g BoothAzFunc<UniqueID>Copy it (Starting with DefaultEndpointsProtocol...) to somewhere.
Go to your working directory and clone the sample code repository from:
git clone https://github.com/Microsoft/function-demo-java-on-azure.git
cd function-demo-java-on-azureAnd make sure you replace the $UniqueId$ in walkthrough/pom.xml with the actual string of your unique ID.
Then open walkthrough/local.settings.json and paste the connection string of your storage account to the value of AzureWebJobsStorage.
Enter the folder walkthrough, and execute:
mvn clean packageThen you may run it by:
mvn azure-functions:runThe timer and the queue functions will be triggered once per 30 seconds. To trigger the HTTP function, you need to execute the following command in a new command line window:
curl -X POST -d "World" http://localhost:7071/api/helloTo terminate the app, press Ctrl + C, in addition, launch some Take Manager and terminate all java.exe processes (you don't need to make sure it disappears from the task manager because some of the java.exe will be automatically restarted; what you need to do is just trigger the End Process on every java.exe).
Try the following command to deploy the function app, and that's it.
mvn azure-functions:deployAnd you will find your functions app named walkthrough-<UniqueID> under Java Demos subscription.
You will also be able to find the URL of the deployed app within the last 10 lines of the command line output. So it is possible to verify that it is actually running on Azure.
curl -X POST -d "World" <Deployed Host URL>/api/helloGet to the built-in terminal by pressing the Ctrl + Backtick.
Enter the folder walkthrough in the built-in terminal, and execute:

Enter the folder walkthrough in the built-in terminal, and execute:
mvn clean packageNavigate to the Debug page of Visual Studio Code by pressing Ctrl + Shift + D; then click the little gear icon (Open launch.json) besides "No Configurations" dropdown; and select "Java".
In the newly created launch.json, locate the Debug (Attach) block, and set the port to be 5005.
Now you run the functions app by:
mvn azure-functions:runWait for the functions host to start, and select the Debug (Attach) item in the dropdown list, and click the little green run icon (Start debugging) beside that dropdown list.
Now you can set the breakpoints in:
Those breakpoints will be hit when the corresponding function is triggered. And when any of them is hit, hover the mouse to some variables, like executionContext or timerInfo, to demostrate that the user could inspect all the execution environment here. And press F5 to continue running.
