Using libraries licensed under LGPL
Hi folks!
I'm building htop in HBASE-11062 now and using Lanterna library to make a
Unix top like user interface:
https://github.com/mabe02/lanterna
Lanterna is a Java library allowing you to write easy semi-graphical user
interfaces in a text-only environment, very similar to the C library curses.
However, I found Lanterna library is licensed under the LGPL.
https://github.com/mabe02/lanterna/blob/master/License.txt
According to the Apache website (
http://www.apache.org/legal/3party.html#criteriaandcategories), it looks
like LGPL License in incompatible with Apache License, but I'm not sure if
we should not use libraries licensed under LGPL.
Could anyone advise me on it?
Regards,
Toshi

Hurray!!!!
We can note the exemption in our NOTICES.txt file.

Thank you for the comments, Stack and Josh.
It looks like the author agreed that they give us special permission to
use Lanterna under Apache 2.0:
https://github.com/mabe02/lanterna/issues/415
In this case, how to proceed? We need to make a note of this
(maybe in http://hbase.apache.org/license.html)? Or we can just use
the library without any notes?
Sorry to bother you, but I'm not familiar with license things.

The only exception to this rule is that if it's an "optional"
dependency. Meaning, if you could use some other dependency in place of
the LGPL one, it's OK. That does not apply in this situation :)
Hopefully the author will agree! The demo of your tool on Tuesday was
quite nice!!

The latter is worth a try.
(These console tools all seem to do GPL or LGPL. Perhaps there is a GPL at
the root of them that they can't avoid).

Thank you for your reply, Duo and Nick.
I understood that we can't use libraries licensed under LGPL at least in
HBase.
Before considering whether I create a new project, I will try to ask the
Lanterna
author to change the license of the library to Apache License or MIT.

My understanding of [0] is that various versions of LGPL are explicitly
prohibited from use as a dependency in Apache Foundation projects.
I’m not a lawyer.

HBase itself can not depend on libraries which are licensed under LGPL. A
possible way is to create a new project, which depend on both HBase and the
LGPL library?
