Groovy SDK 2.1 for Mac could be downloaded from the developer's website when we last checked. We cannot confirm if there is a free download of this app available. The application lies within Developer Tools, more precisely IDE. This free Mac application was originally designed by Apache Groovy project. Please check the Mac app with an antivirus before launch as it is downloaded from the developer's website, and we cannot ensure that it is safe.
From the developer:
This tool makes installing Groovy on any Bash platform (Mac OSX, Linux, Cygwin, Solaris or FreeBSD) very easy. With Groovy 2.6, you can enable the Parrot parser which supports additional syntax options and language features. Groovy has supported multi-assignment statements.
You may want to check out more Mac applications, such as Feathers SDK Manager, Uninstall ZebraLink Multiplatform SDK or Corona SDK by Corona Labs, which might be similar to Groovy SDK.
