Cannot resolve versions with Spring Boot Gradle Plugin

[guardiande]

Hi,

There is a Spring Boot Gradle Plugin to manage Spring dependency versions: https://docs.spring.io/spring-boot/docs/current/gradle-plugin/reference/html/

Unfortunately it does not work with IvyPot:

$ ./gradlew syncRemoteRepositories

> Task :syncRemoteRepositories FAILED
[syncRemoteRepositoriesConfigure] :: Ivy 2.2.0 - 20100923230623 :: http://ant.apache.org/ivy/ ::

Here's the build.gradle:

buildscript {
    ext {
        springBootVersion = '2.0.1.RELEASE'
    }
    repositories {
        mavenLocal()
        mavenCentral()
        maven { url 'https://plugins.gradle.org/m2/' }
    }
    dependencies {
        classpath "org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}"
    }
}

plugins {
  id 'org.ysb33r.ivypot' version '0.7'
}

apply plugin: 'java'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'

group = 'com.digits'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = 1.8

repositories {
    mavenLocal()
    mavenCentral()
}

dependencies {
    compile "org.springframework.boot:spring-boot-starter-web" // :2.0.1.RELEASE"
}

syncRemoteRepositories {
  repoRoot "${buildDir}/repo"

  repositories {
    mavenCentral()
  }

  addAllProjects()
}

When I change the dependencies to

dependencies {
    compile "org.springframework.boot:spring-boot-starter-web:2.0.1.RELEASE"
}

it works.

Maybe related to #21?

[ysb33r]

Maybe there is an issue with how Ivy resolve these kind of dependencies

WIll check when I get a chance, but (unfortunately) only be in about 3 weeks time.

[ysb33r]

I think the issue is related to the way that the spring-boot plugin delays evaluation of the dependencies, which results in null versions being reported to Ivy.

This is going to be a tricky fix and I'll need to look in to the SpringBoot's plugin source code first.
