Windows

Jajuk works with Java 1.8, 9, 11, 13 + You can use the Oracle JRE but we advice to use the fully Open Source AdoptOpenJDK distribution :

• Download the AdoptOpenJDK installer
• Launch the installer with the Updating the JAVA_HOME environment variable and Updates registry keys HKLM\SOFTWARE\JavaSoft options enabled
• Download the Jajuk Windows installer (Jajuk-setup-<version>.exe</version>) and launch it.

Linux (shell installer)

• Install a compatible Java version Jajuk requires a Java Runtime Environment (JRE) 1.8 or later (tested successfully with openjdk 11 and 13). If you get an error similar to java.lang.UnsatisfiedLinkError: Can't load library: /usr/lib/jvm/java-11-openjdk-11.0.5.10-0.fc29.x86_64/lib/libawt_xawt.so, you use a headless JRE. Try to install a full JRE (java-11-openjdk-devel.x86_64 for instance).

Note that we no more provide distribution specific package because it has been proved to be too brittle and time consumming. We now provide a simple shell installer that only sets the PATH and creates the app launcher for the current user. The binaries stay in place.

• Downlaod the jajuk-linux-<version>.tar.gz file
• Extract it into a definitive location and run the installer :

  $ cd <location>
  $ tar xzpvf jajuk-linux-<version>.tar.gz
  $ ./installer 
  

  Note that using the installer is optional, you can simply start jajuk from the extracted location :

  $ ./jajuk
  

MacOS

• Install Java for MacOS
• Download the jajuk-macos-11.0.zip
• Extract the app file and launch it
