From 1a8997c575e50e4736033465f6b1090826f1d100 Mon Sep 17 00:00:00 2001 From: Arnout Engelen Date: Wed, 24 May 2023 12:51:34 +0200 Subject: [PATCH] Document JDK build prerequisites (#336) I think mentioning the need to install Java 8 should be sufficient here: in the vast majority of cases it should be picked up automatically, and otherwise the build error tells you how to explicitly point to it. --- README.md | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) diff --git a/README.md b/README.md index 00c01276b5..1341e027e1 100644 --- a/README.md +++ b/README.md @@ -18,8 +18,9 @@ See https://pekko.apache.org for the documentation including the API docs.
