Hi, I'm embedding a third party library to my project. The 3rdparty library says that one of its files MMBilling.jar must be placed at the ROOT_PROJECT/runtime/ directory, otherwise it will not compile. Following the instruction I was able to compile it correctly in Eclipse, but in intelliJ, doing that still results in a compile error. I'm wondering what is causing this. Could it be the jar itself or IntelliJ having different build process than Eclipse. I attached the offending jar file. Please take a look at it. Thanks!
