Task azureFunctionsDeploy fails if runtime is not configured

[ghost]

Hi everyone,

with the following contents of my Gradle file:

plugins {
  id 'java'
  id 'maven-publish'
  id "com.microsoft.azure.azurefunctions" version "1.4.0"
}

repositories {
  mavenLocal()
  maven {
    url = 'https://repo.spring.io/libs-snapshot-local'
  }

  maven {
    url = 'https://repo.spring.io/libs-milestone-local'
  }

  maven {
    url = 'https://repo.spring.io/release'
  }

  maven {
    url = 'http://repo.maven.apache.org/maven2'
  }
  mavenCentral()
}

dependencies {
  implementation 'org.springframework.cloud:spring-cloud-function-adapter-azure:3.0.10.RELEASE'
  compileOnly 'org.springframework.cloud:spring-cloud-starter-function-web:3.0.10.RELEASE'
  implementation 'io.jsonwebtoken:jjwt-impl:0.11.2'
  implementation 'io.jsonwebtoken:jjwt-jackson:0.11.2'
  implementation 'org.springframework:spring-web:5.2.9.RELEASE'
  compileOnly 'org.projectlombok:lombok:1.18.12'
  annotationProcessor 'org.projectlombok:lombok:1.18.12'

  testImplementation 'org.springframework.boot:spring-boot-starter-test:2.3.4.RELEASE'
  testCompileOnly 'org.projectlombok:lombok:1.18.12'
  testAnnotationProcessor 'org.projectlombok:lombok:1.18.12'
}

group = 'my.company'
version = '0.0.1-SNAPSHOT'
description = 'my-app-name'
sourceCompatibility = '1.8'

publishing {
  publications {
    maven(MavenPublication) {
      from(components.java)
    }
  }
}

tasks.withType(JavaCompile) {
  options.encoding = 'UTF-8'
}

jar {
  manifest {
    attributes 'Main-Class': 'my.springboot.Application'
  }
}

azurefunctions {
  resourceGroup = 'my-resource-group'
  appName = 'my-app-name'
  region = 'westeurope'
  runtime {
    os = 'windows'
  }
  appSettings {
    WEBSITE_RUN_FROM_PACKAGE = '1'
    FUNCTIONS_EXTENSION_VERSION = '~3'
    FUNCTIONS_WORKER_RUNTIME = 'java'
    MAIN_CLASS = 'my.springboot.Application'
  }
}

The azureFunctionsDeploy task was always failing with

> Task :azureFunctionsDeploy FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':azureFunctionsDeploy'.
> java.lang.NullPointerException (no error message)

I had to use the --stacktrace argument to find out, that this happens when the runtime element of the context is accessed at com.microsoft.azure.plugin.functions.gradle.handler.DeployHandler.execute(DeployHandler.java:106). So adding a runtime element into the configuration fixed the problem. Nevertheless, runtime is marked as an optional configuration parameter.

Cheers
Patrick
