Hi @davecramer , Thanks for update . Can you please let me know what was the exact issue and also please let me know which jdk version I need to use? I have tried with jdk-8 here.

[davecramer]

You need to set

pgjdbc.skip.jre6=true
pgjdbc.skip.jre7=false

in gradle.properties

@shivsrivastava , you attempt building stale version, so please figure out what goes wrong.

REL42.2.20 misses this change that is vital for it to build: #2205
As a workaround you could execute ./gradlew :postgresql:removeTypeAnnotations before building 42.2.20, or you could build the latest one on the 42.2 branch which is 42.2.27.
