*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":http://www.oracle.com/technetwork/java/javase/downloads/index.html.
*Note:* Running v2.1-v2.3.1 on Java 8 is supported by specifying
<pre>
com.zfabrik.java.level=7
</pre>
(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.
