HELP!!! Problems with Solutions using IntelliJ IDEA...When I try to run the code for a Codegym task. it runs the last solution instead of the current one. I have to manually change the solution configuration to match the current task. I.e ( I have to change task0319 to task0320 using the solution folder at the top...)
