我正在使用带有 Nomin 作为映射器的 Spring/Groovy 应用程序。之后我的测试在控制台上运行良好gradle build/test。Nomin 使用定义的映射查找 groovy 资源文件。但我不能让它在 Eclipse/STS 中工作。

在此处输入图像描述

我定义了一个 Utils 类来获取资源文件名：

class ResourceUtils {
    static def getMapperResource() {
        ClassPathResource.newInstance("coinmarketcap2coin.groovy").filename
    }
}

My Class using Nomin Mapper 将构造函数调用为：

def nomin = new Nomin(ResourceUtils.getMapperResource())

该文件coinmarketcap2coin.groovy位于src/main/resources. 我必须如何实现getMapperResource它在控制台和 Eclipse 上都有效的方法？

更新：

对我来说，这似乎是src/main/resources路径下的 Eclipse 和 Groovy 类的错误，例如在使用 Nomin 映射器的情况下。

正如您在屏幕截图中看到的那样，它将我coinmarketcap2coin.groovy置于默认包之下。当我将其重命名为 时coinmarketcap2coin.groovymapper，它不会在默认包中显示更多内容，而是直接在src/main/resources.

在这种情况下，它适用于 Eclipse 和带有 gradle 的控制台。我已经尝试在 Eclipse 中配置类路径以排除资源文件夹中的 .groovy 文件，但总是在项目上的 Gradle/Clean 之后，它会再次回到默认包中。

我尝试了一个具有相同星座的迷你示例，但是 maven 项目，我没有那个问题......所以我不知道......它现在对我有用，但不知何故它是一个黑客......如果有人有同样的问题并且一个干净的解决方案我真的很感激知道它。
