Confusing build statements

[martinandersson]

In the README, it is said that command ./gradlew -Pvaadin.productionMode "will build this app in production mode as a WAR archive". In the subsequent section, approximately the same thing ("To build your app for production") is stated about a different command ./gradlew clean build -Pvaadin.productionMode.

This needs to be clarified.

Ideally, we should also explain why we're adding the "clean" hack in the last command. Smells like the Vaadin Gradle plugin or a dependent feature of the build system isn't working properly, hence the "clean".

Actually if you look at the default in build.gradle you can see that it is defined as defaultTasks("clean", "build") so running ./gradlew is the same as running ./gradlew clean build
This should probably be mentioned and the same format used for each case.

lol so much magic everywhere. Don't you get tired of it yourself?

Also, thank you for your answer, of course! =) Still, curious to know why the clean-hack.

For a production build using clean build is to get no development mode files in by mistake, but else it should be fine to not have clean.
I feel we should probably drop clean from the default tasks as it shouldn't be needed for each and every execution and was left there by mistake from the unofficial version.
