由于缺乏gradle依赖关系，无法构建https://github.com/reactor/reactor-samples

Question

我用gradle插件在eclipse中克隆并导入了Gradle项目。

但是我得到了所有反应堆类的重要错误。无法找到项目中引用的任何BUILD.SNAPSHOTS。

./gradlew compileJava :编译程序

失败:生成失败，出现异常。

• 尝试:使用--stacktrace选项运行以获得堆栈跟踪。使用--info或-调试选项运行以获得更多日志输出。

构建失败

Answer 1

我想出了一个更简单的解决方案--遗憾的是，示例本身并没有配置这个条目。理想情况下，应该这样做，因为示例引用快照。

只要添加一个存储库条目来指向spring快照，您就可以找到构建快照:)

repositories {
  mavenLocal()
  mavenCentral()
  maven { url 'http://repo.spring.io/libs-snapshot' }
  jcenter()
}

Answer 2

当前示例需要2.5版本的recator快照版本。由于此快照版本在maven central上不可用，因此您必须手动构建它，因此在构建示例之前，它将出现在您的.m2/repo中。

Answer 3

或者，我们只是跳到了2.5.0，bumped快照和扩展回购落后，它应该很快就会在repo.spring.io上发布，而且无论如何，随着本月M1的发布。很抱歉给您带来不便，我们上周刚刚开始进行这项更改。
