Boot 2.0.0出错。使用Gradle的build-snapshot

Question

我从https://start.spring.io创建了一个版本为2.0.0.build-snapshot的Gradle引导项目，并且没有做任何更改，只是尝试使用以下方法运行应用程序：

    FAILURE: Build failed with an exception.

* What went wrong:
Could not resolve all dependencies for configuration ':compileClasspath'.
> Could not find org.springframework.boot:spring-boot-starter-actuator:.
  Searched in the following locations:
      https://repo1.maven.org/maven2/org/springframework/boot/spring-boot-starter-actuator//spring-boot-starter-actuator-.pom

      https://repo.spring.io/milestone/org/springframework/boot/spring-boot-starter-actuator//spring-boot-starter-actuator-.jar

我怀疑依赖项管理${springBootVersion}标记有问题，如图所示：

https://repo1.maven.org/maven2/org/springframework/boot/spring-boot-starter-acture/[WHERE IS THE version？？？]/spring-boot-starter-acture-[WHERE IS THE version？？？].pom

下面是我配置的回购（粗体部分不是由initialzr生成的：

repositories {
    mavenCentral()
    maven { url 'https://repo.spring.io/libs-snapshot' }
    maven { url "https://repo.spring.io/snapshot" }
    maven { url "https://repo.spring.io/milestone" }
}

FAILURE: Build failed with an exception.

Answer 1

您需要添加：

maven {
    url 'https://repo.spring.io/libs-snapshot'
}

存储库块（main和buildscript）
