Question

我正在尝试从命令行运行Groovy脚本。它在intellij的gradle项目中运行良好，但是当我尝试通过命令行运行它时，却遇到了类似这样的错误

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup 
failed:
/home/tpulayan/jenkins- 
watcher/src/main/groovy/attempt_authentification.groovy: 1: unable to resolve 
class in.ashwanthkumar.slack.webhook.Slack
@ line 1, column 1.
  import in.ashwanthkumar.slack.webhook.Slack
  ^

1 error

我的代码：

@Grapes(
    @Grab(group='in.ashwanthkumar', module='slack-java-webhook', 
version='0.0.7')
)

import in.ashwanthkumar.slack.webhook.Slack

use(TimerMethods) {
    def timer = new Timer()
    def periodSeconds = 600

    new Slack()
            .icon(':exclamation:')
            .sendToChannel('jenkins-monitoring')
            .displayName('Jenkins Watcher')
            .push(new SlackMessage("Jenkins Watcher started at ${new Date()}. Started to monitor the status of deb-jenkins-prd..."))

    def task = timer.runEvery(1000, periodSeconds * 1000) {
        def response = getAuthentication().statusCode
        if (response != 200) {
            new Slack()
                    .icon(':exclamation:')
                    .sendToChannel('jenkins-monitoring')
                    .displayName('Jenkins Watcher')
                    .push(new SlackMessage("Login attempt by Jenkins Watcher failed at ${new Date()}. This could indicate that Jenkins is stuck! Request response code is: ${response}"))
        }
    }
}

我想这与类路径有关，但是我无法解决。

非常感谢您的帮助！

我已经使用@Grab更新了我的代码，但不幸的是，从命令行运行它时出现了此错误：

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:

build.gradle中的

似乎您已定义依赖项。

您可以将所有依赖项（* .jar）放入./lib目录中，并像下面这样运行groovy脚本：

groovy -cp ./lib/* MyScript.groovy

或者您可以直接在Groovy脚本中使用Grape/Grab指定所有依赖项，这样您的命令行将很简单，并且groovy将在脚本启动时下载所有依赖项

groovy MyScript.groovy

Groovy：从命令行运行时无法解析类
