使用Gradle启动2.0.0.BUILD-SNAPSHOT时出错

我创建了一个Gradle启动项目，版本为2.0.0.BUILD-SNAPSHOT，未做任何更改，并尝试使用以下工具运行该应用程序：

gradle bootRun

我得到以下错误

    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/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'应用程序启动正常

我怀疑dependency management${springBootVersion}标记有问题，如图所示：

[版本在哪里？]/spring boot starter actuator-[版本在哪里？].pom

以下是我配置的回购协议（粗体部分不是INITIALZR生成的aut:

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，但初学者pom仍然存在一个问题：

您需要添加：

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

到您的存储库块（main和buildscript）

这可能对某些依赖项有所帮助，但初学者pom仍然存在一个问题：两者都有。问题在于那些REPO中的启动器。它们是错误的：缺少]/spring boot starter aop-[VERSION MISSING].pomBUILD快照版本不在maven central中。您找错了位置。请看这里：发布您的整个build.gradle
