使用 Gradle 启动 2.0.0.BUILD-SNAPSHOT 时出错

Question

我从 https://start.spring.io 创建了一个版本为 2.0.0.BUILD-SNAPSHOT 的 Gradle 启动项目，并且没有进行任何更改，并尝试使用以下命令运行应用程序：

gradle bootRun

我收到以下错误

    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://repo1.maven.org/maven2/org/springframework/boot/spring-boot-starter-actuator//spring-boot-starter-actuator-.jar
      https://repo.spring.io/snapshot/org/springframework/boot/spring-boot-starter-actuator//spring-boot-starter-actuator-.pom
      https://repo.spring.io/snapshot/org/springframework/boot/spring-boot-starter-actuator//spring-boot-starter-actuator-.jar
      https://repo.spring.io/milestone/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

现在，当我将版本更改为： springBootVersion = '1.5.3.BUILD-SNAPSHOT'应用启动正常。

我怀疑依赖管理 ${springBootVersion} 标签有问题，如图所示：

https://repo1.maven.org/maven2/org/springframework/boot/spring-boot-starter-actuator/[版本在哪里？？？]/spring-boot-starter-actuator-[版本在哪里？？？].pom

这是我配置的存储库（粗体不是由 INITIALZR 自动生成的：

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

这可能对某些依赖项有所帮助，但 starter pom 仍然存在问题：

FAILURE: Build failed with an exception.

Answer 1

你需要添加：

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

到您的存储库块（主要和构建脚本）
