Question

我对groovy脚本的新手。我在远程盒子上运行脚本。像往常一样使用jfrog delete artifacts脚本（https://www.jfrog.com/blog/advanced-cleanup-using-artifactory-query-language-aql/）。根据我的要求更新了主机。但是当运行命令时，我遇到了方法异常。

Artifactory 4.1.3 rev 40020 PRO

def artifactoryURL = 'http://localhost:8081/artifactory/' // replace this with your Artifactory server
def restClient = new RESTClient(artifactoryURL)
restClient.setHeaders(['Authorization': 'Basic ' + "admin:password".getBytes('iso-8859-1').encodeBase64()]) //replace the 'admin:password' with your own credentials
def dryRun = true //set the value to false if you want the script to actually delete the artifacts

def itemsToDelete = getAqlQueryResult(restClient, query)
if (itemsToDelete != null && itemsToDelete.size() > 0) {
    delete(restClient, itemsToDelete, dryRun)
} else {
    println('Nothing to delete')
}

Answer 1

嗯，错误信息比较清楚。您调用一个方法constructPath()，该方法需要HashMap作为参数，但是给它一个LazyMap，这是不同的。让您的方法constructPath()期望Map，如果LazyMap实施Map，它将有效。

groovy脚本中的MissingMethodException
