The Windows-Installer for Groovy 1.8.0 can now be downloaded from the Groovy Website ( direct link). It takes care of the gory details of a Windows installation, copying files, setting environment variables and file associations. The installation of everything but the binaries including the native launcher is optional.
This is the first release to contain groovy++. Also, this installer does not contain the Griffon builders since the necessary changes to run under 1.8 weren't possible in time for the release. The next installer (1.8.1) will contain them again. Finally, since GPars is now part of the core distribution it is always installed, and is no longer provided as a module.
Currently supported languages for the installer are english, german, spanish, french and brazilian portuguese.
