Unable to drag and drop to Eclipse

Question

I have been draging and dropping from Windows Explorer to Eclipse since I've started using it, and now find myself unable to do so. When I drag a .java file over my package, the mouse cursor stays a circle with a diagonal bar through it and dropping does nothing. I have tried to change my workspace, create a fresh new workspace, deleted eclipse and redownloaded it. It still doesn't work. Making Eclipse run as admin doesn't solve the issue either.

Answer 1

Extract all files from zip folder. It worked for me.

Answer 2

For me it was the missing marketplace client.
It is noticeable when help -> Eclipse Marketplace is missing.
I installed it with help -> Install new Software -> Update Site for 2018-09 -> Eclipse Marketplace

Answer 3

I figured out it was due to viewing the project in Project Explorer instead of Package Explorer.

Right click on a project > Show in > Package Explorer

You'll be able to drag-drop again at this point.

Answer 4

I faced similar problem when trying to drag-drop image file directly from explored zip. After I extracted the zip, drag-drop worked as expected.

Answer 5

I had this issue when Eclipse was running as Administrator. Setting it back just worked.

Answer 6

There are at least two workarounds:

• Use the menu File -> Import -> General -> File System
• or use CtrlC in Windows Explorer, CtrlV in the Package Explorer of Eclipse.
