Make existing projects use the default cache in buildship

I have tested a new gradle project in eclipse and it does use the same cache as the wrapper in project. The question is what do we need to do to fix the existing old projects to use the same cache? We have several very large projects that become a pain when you need to switch from eclipse to command line and back as each one will refetch the same dependencies.

I’m using 4.10.1 on Windows 10, Msysgit and Eclipse Oxygen.
