Support installing docc plugin via env var#845
Merged
Conversation
This is a workaround for `swift package add-dependency` not working due to swift-subprocess pulling it in explicitly: ``` [swift-java] -> % swift package add-dependency https://github.com/swiftlang/swift-docc-plugin --from 1.1.0 error: unable to add dependency 'https://github.com/swiftlang/swift-docc-plugin' because it already exists in the list of dependencies ``` even though ``` -> % swift package generate-documentation error: Unknown subcommand or plugin name 'generate-documentation' Usage: swift package <options> <subcommand> ``` So this is a workaround to enable the plugin in this package

Nowadays (as weird as it is) projects are not expected to have the dependency declared explicitly. It must be added ad-hoc or by the swift package index. Otherwise all kinds of tools break, including swiftlang/docs. It would be ideal that all projects can just add the plugin, but that's not the state of the world nowadays. Meanwhile I did workarounds in adopter projects to unbreak swiftlang/docs building with those added, more details here swiftlang/swift-java#845 cc @heckj
