Groovy：從命令行運行時無法解析類

Question

我正在嘗試從命令行運行Groovy腳本。 它在intellij的gradle項目中運行良好，但是當我嘗試通過命令行運行它時，出現了類似此錯誤

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

我的代碼：

@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}"))
        }
    }
}

我想這與類路徑有關，但是我無法解決。

任何幫助深表感謝！

我已經使用@Grab更新了我的代碼，但是不幸的是，從命令行運行它時出現此錯誤：

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

在build.gradle您似乎已經定義了依賴項。

您可以將所有依賴項（* .jar）放入./lib目錄中，並像下面這樣運行groovy腳本：

groovy -cp ./lib/* MyScript.groovy

或者您可以直接在groovy腳本中使用Grape/Grab指定所有依賴項，那么您的命令行將很簡單，並且groovy將在腳本啟動時下載所有依賴項

groovy MyScript.groovy
