Install and run Z2 in 5 minutes¶
Z2 has the following Java Version requirements
|Z2 Version||Min. Java version required||Max Java version supported||Max language level|
|2.1 - 2.3.1||Java 6||Java 7||Java 7|
|2.4 - 2.5||Java 8||Java 8||Java 8|
|2.6||Java 9||Java 11||Java 10|
|2.7||Java 9||Java 11||Java 11|
|2.8||Java 9||Java 13||Java 13|
|2.9b||Java 8||Java 8||Java 8|
|2.9.1||Java 11||Java 16||Java 15|
|2.9.1b||Java 8||Java 8||Java 8|
|2.10||Java 11||Java 18||Java 18|
|master||Java 11||?||Java 18|
Note: Most samples suggest to use the master branch. You may choose another version branch (please check the respective repository).
Make sure you have a corresponding Java Development Kit (JDK) or Java Runtime Environment (JRE) installed. If in doubt, go to Download Java SE.
Note: Running v2.1-v2.3.1 on Java 8 is supported by specifying
(or 6, if that is your desired compilation language level) in
<home>/run/bin/runtime.properties. By this the Java compiler version detection does not fall back to a lower level.
It is beneficial to use the Eclipse IDE (Ganymed, Helios, Indigo, Kepler work all fine). There's a small Eclipse plug-in called "Eclipsoid" which makes it easier to develop z2 applications within Eclipse (see Step 3 - First steps with Z2 on Git for more details). That plugin is also available for Intellij. However you can use any IDE (including vi and notepad) together with z2.
Creating a home for Z2¶
This is a best practice approach (and other approaches are possible). We recommend to keep the repositories and the IDE workspace close together. This way we don't need to adjust the path settings in the Z2 configuration files and they can remain relative paths.
Create a folder called z2-base inside your favorite/home/development/what-ever directory and enter it:
mkdir z2-base cd z2-base
Installing the z2-base Distribution¶
The fastest way to start with z2 is by installing the z2-base distribution that contains the z2-core and complete copy of the z2-base.base component repository in one installable archive and requires no access to remote repositories (see also How_to_create_your_own_system for more details).
In order to install, download from the web site and unpackage.
mkdir install cd install
On Mac-OS or Linux run:
wget http://download.z2-environment.net/z2/z2-base-v2.10.zip unzip z2-base-v2.10.zip
On Windows download the archive and unpack using the Windows explorer. Make sure to unpack into the installation folder previously created.
This will create a folder z2-base.core that contains the complete version 2.9 z2-base installation.
Make sure to have a Java Development Kit (JDK) or a Java Runtime Environment of version 9 or later installed and executable. Test this by running
On Mac OS or Linux run:
cd z2-base.core/bin ./gui.sh
On Windows run:
cd z2-base.core\bin gui.bat
(In order to check that z2 is up, when you see "Completed home process initialization", try http://localhost:8080/adm with user "z*" and password "z".)
This tutorial will continue by showing you how to develop with Z2. If you ask yourself how to add remote repositories, please check out How_to_create_your_own_system.
