Subject: [meta-java][RFC][PATCH 2/7] layer.conf: allow multiple Java SDKs & runtimes to co-exist
Date: Fri, 27 Jul 2018 14:29:18 +0100	[thread overview]
Message-ID: <20180727132923.15149-2-git@andred.net> (raw)
In-Reply-To: <20180727132923.15149-1-git@andred.net>

From: André Draszik <andre.draszik@jci.com>

Using MULTI_PROVIDER_WHITELIST, we can instruct Bitbake to not complain
if multiple recipes provide or runtime provide the same Java environment.

This is a common use-case, and Java packages don't conflict with each
other as they are typically installed under a different prefix, while still
providing (more or less) the same features.
