Groovy腳本中的MissingMethodException

Question

我是groovy腳本的新手。 我在遠程機器上運行腳本。 像往常一樣使用jfrog delete構件腳本（ https://www.jfrog.com/blog/advanced-cleanup-using-artifactory-query-language-aql/ ）。 根據我的要求更新了主機。但是每次運行命令時，我都會丟失方法異常。

Artifactory 4.1.3 rev 40020 PRO

好吧，錯誤消息相對清晰。 您調用的方法constructPath()期望將HashMap作為參數，但是給它一個LazyMap ，這有所不同。 使您的方法constructPath()期望使用Map並且如果LazyMap實現Map ，它將起作用。
