So I was having a problem which has been posted before, about not being able to open the Minecraft project and not seeing any subfolders when I clicked on the arrow to the left. Well, I followed a user's suggestion and ran the command .\gradlew eclipse (the .\ is because I was in Powershell rather than the command prompt, and I was in the same directory I was trying to write commands for). Anyway, it worked and I was able to see the subfolders in the Minecraft project in Eclipse. But then there was a red arrow on the Minecraft project, and it returned 60 errors which all basically said: Build Path Problem. How do I resolve this? Thanks!
