Sometimes, when I do code cleaning, I happen to rename my solutions and projects.
Usually I also rename folders on disk to keep it in line.
I know that I need to edit the sln file to put in the renamed folders, so the solution can find the projects.
Usually all goes smoothly, but once after such renaming, I could not build my SSDT solution.
I got the:
04018 Error – SqlBuildTask failed unexpectedly …
(with no further error details)
I tried:
- restarting VS
- unload / reload projects
- rebuild (one by one)
Some of the base projects did rebuild ok, but others did not.
Actually – I already have an answer, that worked … so someone can find it useful.
It helped when I deleted all *.dbmdl and *.jfm files within solution folder/subfolders, and then restarted VS and rebuild.
