In a unit test I need to import a csv file. This is located in the resources folder, i.e. src/test/resources
Probably just useful if you have the file available, for example when doing unit tests - this will not load it out of a jar AFAIK.
URL url = Thread.currentThread().getContextClassLoader().getResource("mypackage/YourFile.csv"); File file = new File(url.getPath()); // where the file is in the classpath eg. <project>/src/test/resources/mypackage/YourFile.csv
