Storing and Retrieving blobs fails to compile on both Gitpod and Ubuntu 20.04

I didn't expect the gitpod to crash too. I find myself back in Maven Hell.

Hi @francisdomoney@aol.com,

Fatal error compiling: error: invalid target release is a compile time error when the target release (as specified in the pom.xml) does not match the Java release defined in JAVA_HOME.

On Ubuntu 20.04 you probably have Java 11, so make sure that your pom.xml reflects that.

This is independent of storing and retrieving blobs.

Hope this helps!

My bad. The prerequisites states JDK 14. (JDK 14 reached General Availability on 17 March 2020.)


Maven runs properly on my Ubuntu box now I have installed it but I am not allowed sudo privilege on gitpod to upgrade there

Hi @francisdomoney@aol.com,

which prerequisites state JDK 14? I must have missed that :)
