Google cloud platform 有没有一种方法可以轻松导入云数据融合中的自定义插件？

我正在使用云数据融合建立一个管道，我想导入我自己的自定义插件。有什么简单的方法可以导入它吗

我已经尝试使用Studio部分中的

导入

按钮，但它给了我一些工件方面的问题。我还尝试使用

+

按钮添加一个新实体，并上传.jar和.json文件，但它不返回任何消息

但是，在

App Fabric

日志中，实际遇到了以下错误：

我是云数据融合新手，以前从未使用过CDAP。这些错误有什么解释吗？

您可以导入一个管道，但是如果您已经创建了一个插件，那么您可以通过单击绿色的

“+”

，然后选择您已经完成的

“plugin”>“upload”

上传插件。你能分享你的插件JSON吗？

好的，我也尝试过这种方法。我的JSON如下所示：

For example, you may want to connect a sink\r\nto this plugin in order to store and later examine the error records.\r\n\r\nProperties\r\n----------\r\n**messageField:** The name of the error message field to use in the output schema. Defaults to 'errMsg'.\r\nIf this is not specified, the error message will be dropped.\r\n\r\n**codeField:** The name of the error code field to use in the output schema. Defaults to 'errCode'.\r\nIf this is not specified, the error code will be dropped.\r\n\r\n**stageField:** The name of the error stage field to use in the output schema. Defaults to 'errStage'.\r\nIf this is not specified, the error stage will be dropped.\r\n\r\n\r\nExample\r\n-------\r\nThis example adds the error message, error code, and error stage as the 'errMsg', 'errCode', and 'errStage' fields.\r\n\r\n    {\r\n        \"name\": \"ErrorCollector\",\r\n        \"type\": \"errortransform\",\r\n        \"properties\": {\r\n            \"messageField\": \"errMsg\",\r\n            \"codeField\": \"errCode\",\r\n            \"stageField\": \"errStage\"\r\n        }\r\n    }\r\n\r\nFor example, suppose the plugin receives this error record:\r\n\r\n    +============================+\r\n    | field name | type | value  |\r\n    +============================+\r\n    | A          | int  | 10     |\r\n    | B          | int  | 20     |\r\n    +============================+\r\n\r\nwith error code 17, error message 'invalid', from stage 'parser'.
