Question

为了简洁起见，我删除了以下管道作业的Managed Jenkinsfile。

#!groovy
import groovy.json.JsonSlurperClassic

def json = new File("TEST_JSON.json").text
def data = new JsonSlurperClassic().parseText(json)

def string_1 = data.test

                        build_cmds = [];
                        for (option in data.options) {
                            if ((option.mpss_flavor == MPSS_FLAVOR) && (option.target == TARGET)) {
                                build_cmds.addAll(option.build_commands);
                            }
                        }
                        return build_cmds;
                    '''
                ]
            ]
        ]
    ])
])

以及以下JSON文件包含配置

    {
    "test": "TEST STRING FROM JSON",
    "options": [
        {
            "mpss_flavor": "MPSS1",
            "target": "TARGET1",
            "build_commands": [
                "BUILD_COMMAND_1"
            ]
        },
        {
            "mpss_flavor": "MPSS2",
            "target": "TARGET2",
            "build_commands": [
                "BUILD_COMMAND_2",
                "BUILD_COMMAND_3"
            ]
        }
    ]
}

我想在更新JOSN文件时自动为Job配置参数（我完全知道，在JSON Update之后运行的第一个Job将不包含预期的更改，但这对我们来说是可以的）。 MPSS_FLAVOR和TARGET显示了预期的值。但是，BUILD_CMD选择参数返回错误。当我在命令行中使用静态定义的MPSS_FLAVOR和TARGET运行groovy脚本代码时，脚本可以正常工作，并且返回的build_cmds与预期的一样。但是，通过Jenkins UI，它显示为ERROR（Fallback脚本）

我尝试了几次迭代都没有成功。我确信这是一个小错误，我可以找出。

“我的问题”有什么办法可以查看用于选择参数以隔离问题的脚本的打印日志。

更新对于Job中定义的Jenkins文件，相同的代码也可以正常工作。问题似乎特定于Managed Jenkins文件

使用try-catch换行脚本

try{
   ...your parameter script here
}catch(Throwable t){
    return [t.toString()]
}

在这种情况下，您会看到错误作为参数值

Groovy脚本在Jenkins作业中失败，但可以从命令行正常运行
