I have a maven project which I develop using intellij IDEA. 我有一个使用intellij IDEA开发的Maven项目。 I have specified a resource directory in intellij which contains some configuration files and data files. 我在intellij中指定了一个资源目录，其中包含一些配置文件和数据文件。 When I run the program in intellij, there is no issue, but I would like to access these files when I run the jar-file from command line also, and I do not know how to specify for maven that a directory is a resources directory without it being copied into the jar-file, which I do not want. 当我在intellij中运行程序时，没有问题，但是当我也从命令行运行jar文件时，我想访问这些文件，而且我不知道如何为maven指定目录是资源目录而不将其复制到我不想要的jar文件中。 Is there a flag to java to point out the resources directory? 是否有java标记java资源目录？

Edit: To be clear, I have my jar file and I want to access a resource directory located outside my jar file using the classLoader. 编辑：明确地说，我有我的jar文件，我想使用classLoader访问位于我的jar文件外部的资源目录。 However, it seems as I cannot use -classpath to specify where the classLoader should look, as there is no difference in behaviour. 但是，似乎我不能使用-classpath来指定classLoader的外观，因为行为没有区别。

I can of course open a normal text file, but I would rather have it work from the classLocader machinery. 我当然可以打开一个普通的文本文件，但是我希望它可以在classLocader机制中运行。

If you are using Maven stucture you shoud have 2 directories - java/main/src with sources and java/main/resources with app resources. 如果您使用的是Maven结构，则应该有2个目录-带源的java/main/src和带应用程序资源的java/main/resources resources。 Both are copied into JAR 两者都复制到JAR中
