我有以下代码，我正在使用 Groovy 2.4.3 从 Jenkins 非系统 Groovy 脚本执行

private void readJsonFile() {
    if (testsValid == false) {
        def jsonSlurper = new JsonSlurper()
        try {                   
            println "FileReader("+jsonFileName+")"
            def fr = new FileReader(jsonFileName)
            println "About to slurp from FileReader "+fr
            println "Class: " + fr.getClass()
            tests = jsonSlurper.parse(fr)
        } catch (FileNotFoundException e) {
            println "Properties File Not Found: "+jsonFileName
            e.printStackTrace()
        } catch (IllegalArgumentException e) {
            println "Illegal Argument: " + e.getCause()
            e.printStackTrace()
        }
    }
}

但是，当我运行它时，我得到以下异常：

FileReader(/var/lib/jenkins/workspace/2TierUtmsLog2/resources/utmsdata.json)
About to slurp from FileReader java.io.FileReader@125d92c
Class: class java.io.FileReader

JsonSlurper.parse(Reader r) 方法确实需要一个 Reader，所以我不明白为什么这不起作用。我也尝试过使用 JsonSlurper.parse(String s) 方法，但得到了同样的错误。我还打印了通过 FileReader 读取的内容，它是正确的。

谁能发现我做错了什么，或者这是我遇到的另一个 Jenkins 限制。

添加了请求的信息： jsonSlurper: groovy.json.JsonSlurper@19e733e Print of new File(...) { "job": [ { "jenkins_name": "ForceAResult-fail", "utmsEnabled": "1", "utmsCycleId": "1", "utmsProejct": "Unity", "utmsTeam": "CA-SS System Software", "utmsTestName": "Force_a_test", "utmsTestPlanId": "2", "utmsTestSetId": "3", }, { "jenkins_name": "ForceAResult-pass", "utmsEnabled": "1", "utmsCycleId": "1", "utmsProejct": "Unity", "utmsTeam": "CA-SS System Software", "utmsTestName": "Force_a_test", "utmsTestPlanId": "2", "utmsTestSetId": "3", } ]}

添加了 Divesh 的信息
