Running Nomin Mapper under Eclipse cause NominException: Resource not found - gradle

Question

I am using a Spring/Groovy application with Nomin as mapper. My Tests run fine on console after gradle build/test. Nomin finds the groovy resource file with the defined mapping. But I dont get it work in Eclipse/STS.
I defined a Utils class to get the Resource File Name:
class ResourceUtils {
static def getMapperResource() {
ClassPathResource.newInstance("coinmarketcap2coin.groovy").filename
}
}
My Class using Nomin Mapper calls the constructor as:
def nomin = new Nomin(ResourceUtils.getMapperResource())

The file coinmarketcap2coin.groovy is under src/main/resources. How do I have to implement the getMapperResource method that it works on both console and Eclipse?
UPDATE:
For me it seems to be a bug with Eclipse and Groovy-classes under src/main/resources path, e.g. in case using Nomin mapper.
As you see in the screenshot it puts my coinmarketcap2coin.groovy under default package. When I rename it as coinmarketcap2coin.groovymapper, then it doesnt show it more in the default package but directly under src/main/resources.
In that case it works on both, Eclipse and Console with gradle. I already tried to configure the classpath in Eclipse to exclude .groovy files in the resource folder, but always after Gradle/Clean on project, it makes it back again in the default package.
I tried an mini example with same constallation, but maven project, there I didnt have that problem ... So I dont know ... It works for me now, but it is a hack somehow ... if somebody had same problem and a clean solution I would really appreciate the know about it.
