New project generation may create invalid Package.swift

[selalipop]

Unfortunately I'm not sure about the input I entered during the wizard to cause this (The "Use fluent" question was answered yes), but my generated project failed to build:

error: manifest parse error(s):
Invalid semantic version string '-alpha'

caused by this line in Package.swift:

.package(url: "https://github.com/vapor/fluent--driver.git", from: "-alpha")

Replacing that with a valid repo and version fixes it

It looks like the selection I entered for my database was invalid, and so toolbox generated a line without the DB driver and version

A workaround for others having this issue. Replace the following lines in the generated Package.swift:

.package(url: "https://github.com/vapor/fluent--driver.git", from: "-beta")
...
.target(name: "App", dependencies: [ ... "FluentDriver", ... ]),

with the appropriate driver. For Postgres:

.package(url: "https://github.com/vapor/fluent-postgres-driver.git", from: "2.0.0-beta")
...
.target(name: "App", dependencies: [ ... "FluentPostgresDriver", ... ]),

You'll also have to change the import statement at the top of configure.swift to import the correct fluent driver:

import FluentPostgresDriver
