Groovy的安装

Steps

• Download the latest Grails release
• Extract the archive into an appropriate location; typically C:\grails on Windows or ~/grails on Unix
• Create a GRAILS_HOME environment variable that points to the path where you extracted the archive (eg C:\grails on Windows or ~/grails on Unix)
• If you have not set the JAVA_HOME environment variable yet, create JAVA_HOME environment variable that points to the path where you have installed Java
• Append a reference to the "bin" directory within the Grails directory to your PATH variable (eg %GRAILS_HOME%\bin on Windows or $GRAILS_HOME/bin on Unix). Note that, for Windows, both PATH and GRAILS_HOME must be defined at the same environment variable level (eg. 'System variables') rather than across environment variable levels (eg. PATH under 'System variables' and GRAILS_HOME under 'User variables')
• Type "grails" at the command line, if a help message is displayed you are ready to start using Grails!
• If you get an error message, try to chmod +x the grails script inside the bin directory.
