Sometime if you are importing the portal web project or java project , even after doing clean build it throws error.... 'This project needs to migrate WTP metadata'
There are possible solution to this issue :
1) Delete the .settings folder from the project , refresh the workspace and clean build.
2) Right click on the project and click 'validate'.
3) Delete the .metadata file and create the new workspace. This should be the last option as it may require a lot of rework to set up the workspace.
For me first two option worked , however we used the third option also in one of the case.
