Hi @sangare,

currently you need Java 8 for RapidMiner Studio.
There are OpenJDK and Amazon Corretto versions of Java 8, both work well. I use this:
OpenJDK Runtime Environment Corretto-8.222.10.1 (build 1.8.0_222-b10)

Best regards,

Hi @BalzasBarany,

Thank you very well for your reply. So RapidMiner does not work with advanced version of java ? It only works with java 8?

Best regards

Hi @sangare,

Java 8 and Java 11 are different branches. After Java 8, the system was modularized and a lot of changes were made. 11 is not more "advanced" than Java 8, it is an incompatible version for preparing future developments.

Many established Java based applications are on the Java 8 branch. RapidMiner development is working on making the changes necessary to run on Java 11+, but it doesn't have a high priority, and for now, you have to use Java 8 if you want to use RapidMiner.

In addition,

switching between different Java versions is very simple and can be done with the

sudo update-alternatives --config java

command. For instance if there are other programs that specifically require a higher Java version.

Best,
