gradle - 如何将码头或gretty导入我的gradle脚本

Question

我正在尝试从行动中的书中尝试gradle示例“todo-webapp-jetty” 。可以在here中找到。经过几次搜索，我发现不再支持 jetty 。相反，我们需要使用gretty插件(最好是org.gretty提供的插件)。但是仍然没有运气。我的构建脚本与示例相同，只是调整为使用gretty插件。

使用plugins块，这可以正常工作，但仅在我执行jettyRun任务之前。执行jettyRun任务后，控制台停留在87％:

plugins{
    id 'java'
    id 'war'
    id 'org.gretty' version '2.2.0'
}
............

但是如果没有插件阻止，它将无法正常运行，每当我运行构建时，我都会收到以下错误消息:

任何指导，不胜感激。

当执行正在启动和运行应用程序的任务(例如jettyRun或bootRun)时，这是Gradle的“正常”行为:您将在应用程序执行时看到<===---> XY% EXECUTING [...]消息。

例如，使用Spring Boot bootRun任务，您将拥有:

$ ./gradlew bootRun

> Task :bootRun

  .   ____          _            __ _ _
 /\\ / ___'_ __ _ _(_)_ __  __ _ \ \ \ \
( ( )\___ | '_ | '_| | '_ \/ _` | \ \ \ \
 \\/  ___)| |_)| | | | | || (_| |  ) ) ) )
  '  |____| .__|_| |_|_| |_\__, | / / / /
 =========|_|==============|___/=/_/_/_/
 :: Spring Boot ::        (v2.0.6.RELEASE)

<=========----> 75% EXECUTING [1m 58s]
> :bootRun

您应该在应用程序中配置日志记录，以使一些日志跟踪在STDOUT中可用，通常您会看到该应用程序已正确启动。

从您的堆栈跟踪:

==>您需要在存储库块中添加 jcenter()，因为所需的 gretty-runner-jetty9-2.2.0.jar依赖项在maven中央存储库中不可用。

repositories {

}
