Build failing with Java 11

Get Help

As per development guide, we support Latest Java. And I was hoping Java 11 will work. I have a good feeling that Java 11 used to work earlier. Following is trace.

  version.properties generated successfully.

Hi @tachniki
You can remove the (java/check-java-8) check in ./bin/build-mb/src/build.clj and try without.
We had a lot of problems with gettext, so we are building using Java 8 for the official releases, which this is the script used for that too.

Will there be issue running metabase with java 11 if we build using java 8?

@tachniki No, just like the official releases are build using Java 8, they run on newer versions too.

@flamber Thanks a lot. You are always a great help.
