azure-webapps-java-war-service-principal.yml

# This workflow will build and push a Java application to an Azure Web App when a commit is pushed to your default branch.
#
# This workflow assumes you have already created the target Azure App Service web app.
# For instructions see https://docs.microsoft.com/en-us/azure/app-service/quickstart-java?tabs=javase&pivots=platform-linux
#
# To configure this workflow:
#
# 1. Set up Service Principal deployment credentials for your workflow.
#    For more information: https://learn.microsoft.com/en-us/azure/app-service/deploy-github-actions?tabs=userlevel%2Cjava#1-generate-deployment-credentials
#
# 2. Configure GitHub secrets AZURE_CREDENTIALS.
#    For instructions on how to configure these: https://learn.microsoft.com/en-us/azure/app-service/deploy-github-actions?tabs=userlevel%2Cjava#2-configure-the-github-secret
#
# 3. AZURE_WEBAPP_NAME needs to be created in the Github repo under Settings > Environments.
#    Create a new Environment 'Development', then create a new environment variable with the name 'AZURE_WEBAPP_NAME' and the webapp name as the value.
#
# 4. Optionally, change the JAVA_VERSION environment variable below.
