Running Scala IDE 4.7.1 on OpenJDK11

[Silvio]

I have OpenJDK11 installed on my Linux desktop (Ubuntu 18.10). I use it to run Eclipse and build my Java and projects with it. Although Scala-IDE requires JD8 I have been using it with newer JDK versions for quite some time. Working with JDK9 and JD10 worked flawlessly for me. Since I upgraded to JDK11 I had to do some tweaking to get Scala-IDE working but it seems to run for the most part now, with the exception of one thing: each change to a source file forces a complete rebuild of all my Scala sources.

This was never a problem before (upto and including JDK10) so I was wondering if there are some more tweaks I could do to solve this problem.

Thanks in advance for any pointers.

I forgot to mention that I run Eclipse Oxygen 4.7.3a.

Hi Silvio

I for one would be very interested to know more about these 'tweaks' you had to make to get a functioning Eclipse+Scala with recent JDK. Until now I was unable to obtain something working.

If you could share your tips it would be much appreciated!

Thanks,

Sylvain

Hi,

I'm currently running Eclipse  2018-12 M2 (4.10.0M2) Build id: 20181108-1653 with https://storage.googleapis.com/scala-ide-photon/ (Build 4.7.1.201809291829, which includes Scalac 2.12.7 and Zinc 1.2.2) on JDK 11.0.1 

Everything works as expected, including incremental compilation.

Hope that helps,

Rafał

I did some checking and as it turns out the only tweaks I needed was when I was running an earlier 4.7 Eclipse version. Version 4.7.3a seems to work fine with both JDK11 and the scala IDE 4.7.1.v-2_12. Except for the rebuilds...

Since Rafal seems to have a better working config I am going to try that now.

Hi Rafal,

I used the link you provided to downlad Scala-IDE for Photon and that helps a lot. How did you find this version of Scala-IDE? It is not listed on the site anywhere.

Thank you for the pointers,

Silvio
