Package not found error when building the maven project

I have created a maven project and i am going to use a .jar file that already created by someone. I have added it into the class path and used it and there are no errors showing in eclipse. But when i try to clean build the project there is an error as follows.

You have two packages with same case insensitive names com.MobiOs to com.mobios which represent physically two directories with same case insensitive names. This can lead to an issue if your file system is case insensitive, or expect specific case as lower case.



Java's package names should be lower case:




Package names are written in all lower case to avoid conflict with the names of classes or interfaces.




If you are not convinced, see comment:




On some versions of some Windows file systems names that are entered in all caps are displayed in all lowercase as the default. This is probably to be friendly towards files from systems that don’t distiguish case — these may come in in all uppercase and look better in all lowercase. While the file name is still uppercase behind the scenes, this may have caused confusion
