I check in questions database and find this: link but problem doesn't solve.
My pc have windows 10 and eclipse Neon.3 Release (4.6.3), goclipse is installed, my set for Go are:
C:\Go
C:\Go\workspace
tools path are:
C:\Go\bin\bin\gocode.exe
C:\Go\bin\bin\guru.exe
C:\Go\bin\bin\godef.exe
but I think tools work.
I search for this by 3 days. thank for your help.
You should write the code inside folder which present inside src folder, ie the src folder shouldn't contain any *.go files it can contain folder which contains go files.
Here is an example,
> New_Project/
├── bin
│ └── test.exe
├── pkg
│ └── windows_amd64
└── src
├── strlocal
│ └── file1.go
└── test
└── main.go
