The site that the plugin previously was hosted on (plugins.jasoft.fi) was recently terminated as Gradle provides a much better way of serving the plugins via the
plugins {} block.
plugins { id 'fi.jasoft.plugin.vaadin' version '1.0'}
This looks correct and should work.
Could you make sure you do not have any line like this in any of your
build.gradle files:
apply from: 'http://plugins.jasoft.fi/vaadin.plugin'
[/code]If you do, just remove it. It is not needed any more.
Also make sure that gradle doesn't run a cached old version of your build gradle file. You can do that by running [code]
gradle --no-daemon --recompile-scripts build
Thank you for saving me on this one. Was really scratching my head on what was going on here. Now the deadline tomorow morning is a matter of coding, not fixing the build-env
