When I am trying to deploy a JAR artifact to artifact feed in Azure DevOPS facing the below issue.
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.8.2:deploy-file (default-cli) on project: No transfer protocol found. -> [Help 1]

Below is my YAML code:
- task: Maven#3
displayName: 'Maven Deploy'
inputs:
mavenPomFile: 'pom.xml'
goals: 'deploy:deploy-file'
options: '-DgroupId="com.mycompany" -DartifactId="s-demo-cicd" -Dversion="1.0.1" -
Dpackaging=jar -Dfile="demo-1.0.1-mule-application.jar" -DgeneratePom="true" -
DrepositoryId="$AZURE_FEED_ID" -Durl="$AZURE_FEED_URL"'
I have added required dependencies in POM.xml file.
<distributionManagement>
<repository>
<id>demo-mule</id>
<url>https://pkgs.dev.azure.com/demo-mule/_packaging/demo-mule/maven/v1</url>
<releases>
<enabled>true</enabled>
</releases>
<snapshots>
<enabled>true</enabled>
</snapshots>
</repository>
</distributionManagement>
Please help me understand where I need to make the changes or updates.

To pass a variable into the parameters of the Maven task, make sure you use the correct notation. It can be a bit confusing at times.
In this case use $(...) instead of $.... So your task would look like this:
- task: Maven#3
displayName: 'Maven Deploy'
inputs:
mavenPomFile: 'pom.xml'
goals: 'deploy:deploy-file'
options: '-DgroupId="com.mycompany" -DartifactId="s-demo-cicd" -Dversion="1.0.1" -
Dpackaging=jar -Dfile="demo-1.0.1-mule-application.jar" -DgeneratePom="true" -
DrepositoryId="$(AZURE_FEED_ID)" -Durl="$(AZURE_FEED_URL)"'
