I'm trying to build Kibana, and following the instructions in contributing.md.

Every time I run the Git command in contributing.md, it gits the 5.0.0 development version. In any case, I'd appreciate any help that could be provided to allow me to be able to build Kibana under Ubuntu Linux or Windows 10. Thanks... ---

> [@johncst](#): > > Unsupported major.minor version 52.0 Your issue on Linux appears to be your JDK is not up to 1.8 but that's required for Elasticsearch 5.0 (which is master). (it would be nice if it said "Unsupported JDK 1.7" or something more obvious) Doing a "build" on Windows is not currently supported but there's a PR I'm assigned to test [Fix build windows cygwin by repocho · Pull Request #6267 · elastic/kibana · GitHub](https://github.com/elastic/kibana/pull/6267). You could look at that and see if it helps/ Please add a comment on the PR if you're successful or not. But you don't actually have to "build" to make changes and submit PRs with your changes. You can still change source and run Kibana to test without that "build" step. Regards, Lee ---

Thanks for the help Lee! I posted the results of the Windows attempt on Google. On Linux, after updating the JDK, I was able to get the targets built. On the first attempt, I got a "unexpected EOF" during the optimize step, and the build stopped. I ran the build a 2nd time with --force, and got the targets built. The optimize step showed "stopped". I ran it a 3rd time without --force, and got the same results; targets built but optimize showed "stopped". Thanks... ---
