Being GitHub project, 7Bee doesn't offer binaries so they should be built. 7Bee is a self building tool, however if you build it first time, you need bootstrap it. You can use either bootstrap or bootstrap.bat accordingly your platform. Needless to remind that 7Bee is Java application so you have to have Java version 7 or better installed. The Linux bootstrap script is more advanced and you need just run it and proceed with instructions. The Windows script may require adjust JDK path and also download JSCH and place it in 3rdparty\jsch\lib. bee.jar will be created in lib directory after running bootstrap. However before using 7Bee, it is recommended to install it.
Obtain administrator privileges of your platform. sudo can be used on Linux, or cmd as Administrator on Windows. Type
java -jar ./lib/bee.jar install
java -jar .\lib\bee.jar install
Note that if you are on Linux/Mac/FreeBSD, then bootstrap script will offer you an installation. You will be prompted few simple questions, you can just use default answers. Keep attention only to JDK root directory on WIndows systems. If your platform is Windows, then it is recommended to add 7Bee installation bin directory in your SYSTEM path. Just change Windows environment to add the path as the installation script advises. Now you should be able to launch bee command and execute build scripts without limitations.
