How would I find which version of jdk is compatible with Grails 3.2.4?

Question

I was given guidance that it would be jdk.1.8.0_31. However, Googling this jdk did not bring up any results. How could I be certain, and where can I find the download? The newest jdk (17.0.2) will not work with it.

Answer 1

According to the Grails 3.2.4 guide , Java 7 and above should work.

If you really can't use Java 17, the latest long-term support version, I'd recommend Java 11, the previous long-term support version. You can find downloads for all currently-supported versions of Java here .

Answer 2

For Grails 2.4 and below I would stick to java 8, I thinks there were some issues with java 11, some fixed in Groovy 2.5, but you will still see warnings. For Grails 5+, Groovy 3 I would go for java 11. I think better support for Java 17 is coming for Groovy 4.

Grails 3.2.4 uses groovy 2.4.7 Grails 4 uses groovy 2.5.6 Grails 5 uses Groovy 3 Groovy 4 is coming "soon" so it's not in Grails yet

Grails 3 is already EOL so I would get on upgrading.

Answer 3

You can find and download that build version of jdk 1.8.0_31 here: https://www.oracle.com/java/technologies/javase/javase8-archive-downloads.html

It should work with grails 3.2.4.

Grails 3 works with more advanced builds versions of java 8 and more recent versions of java too like java 11.
