== JDK ==

The Stendhal server and legacy client are both written in [https://www.java.com/ Java]. To run either requires a [https://en.wikipedia.org/wiki/Java_virtual_machine Java Runtime Environment (JRE)]. To compile server or client, a [https://en.wikipedia.org/wiki/Java_Development_Kit Java Development Kit (JDK)] is necessary. Most JDK distributions include a JRE.

=== Installing JDK ===

==== JDK on Unix ====

Some Unix/Linux/BSD systems have a JDK pre-installed. If not, most will have a version available from the system package manager.

Example of installing on Ubuntu:

<pre>

# install version 17

$ sudo apt install openjdk-17-jdk

</pre>

Example of installing on Arch:

<pre>

# install default version

$ sudo pacman -S jdk-openjdk

# install version 17

$ sudo pacman -S jdk17-openjdk

</pre>

Example of installing on FreeBSD:

<pre>

# install pre-built package of version 17

$ sudo pkg install openjdk17

# compile version 17 from Ports source

$ cd /usr/ports/java/openjdk17

$ sudo make install clean

</pre>

==== JDK on Windows ====

Packages for Windows can be downloaded from either [https://www.oracle.com/java/technologies/downloads/ oracle.com] or for OpenJDK, from [https://jdk.java.net/ jdk.java.net]. If you download a portable .zip package, you will need to manually configure the PATH environment variable so the system knows where the <span style="color:darkred;">''java''</span> and <span style="color:darkred;">''javac''</span> executables are located. It may also be necessary to configure the <span style="color:darkgreen;">''JAVA_HOME''</span> environment variable. The recommended method is to use an installer package (.exe or .msi) as these will configure the necessary environment variables automatically.

==== JDK on macOS ====

Packages for macOS can be downloaded from either [https://www.oracle.com/java/technologies/downloads/ oracle.com] or for OpenJDK, from [https://jdk.java.net/ jdk.java.net]. But the recommended method is to install from the [https://brew.sh/ Homebrew Package Manager] as it will configure the necessary environment variables automatically.

Example of installing on macOS using Homebrew:

<pre>

# install version 17

$ brew install openjdk@17

</pre>
