java - 在 Streamsets DataCollector 的 Groovy Evaluator 中导入外部 Java 库的问题

问题描述

我正在尝试在 Streamsets DataCollector 软件中正确配置 Groovy Evaluator。我正在使用第 3 方 Java 库geohash-java（请参阅https://github.com/kungfoo/geohash-java）。我从https://mvnrepository.com/artifact/ch.hsr/geohash/1.4.0下载了该库，并在 External Libraries 页面上成功导入了它。

我使用以下 Groovy 代码导入库： import ch.hsr.geohash.GeoHash.

在预览模式下运行时，出现以下错误：

SCRIPTING_04 - Script sent record to error: groovy.lang.MissingPropertyException: No such property: Geohash for class: Script13

谁能告诉我我做错了什么？

解决方案

我只能使用带有别名绑定的库。

import ch.hsr.geohash.GeoHash as geohash
