Thanks Taher,

That's maybe right indeed, I have no ways to check that without trying. So the 
risk is not worth it, let's forget it and those Gradle messages.

And what about parallel ? It can be safely used now.

Locally you can add "org.gradle.parallel=true" in your (where 
you have Gradle installed) that's what I use for a moment.

I removed it and tested using or not --parallel with "gradlew clean build" several time. It does not seems to have any influence on the performances locally

I had  a look at and tried the --scan on 
a build after a clean

I found some possible improvements:

adding "options.fork = true" in tasks.withType(JavaCompile) { w/ and w/o 

Did not note any noticeable performance improvement

Also tried

|tasks.withType(Test){reports.html.enabled =falsereports.junitXml.enabled 

I guess since we have only few tests it does not give any performance 
improvement at the moment. Could be useful later...

So no need to change anything for OFBiz

So far, from Gradle team recommendation, we were not using Gradle daemons in

In both, I recently noticed warnings like

     To honour the JVM settings for this build a new JVM will be forked. Please 
consider using the daemon: Daemon will be 
stopped at the end of the build stopping after processing

There I can read:

     /Continuous integration//
     //Since Gradle 3.0, we enable Daemon by default and recommend using it for 
both developers' machines and Continuous Integration servers. However,
     if you suspect that Daemon makes your CI builds unstable, you can disable 
it to use a fresh runtime for each build since the runtime is
     //completely//isolated from any previous builds./

I think we can try it, what do you think?

Also, I'm using --/parallel /for quite a moment now. Since we switched to 
Gradle 5 I no longer see warnings about that. Should we not use it in demos
and Buildbot builds and maybe enforce it generally?

Thank you for your opinions.
