Subject Re: licenses and copyrights of dependencies
Date Wed, 07 Nov 2018 20:51:44 GMT
I used to use and also see some other projects use the following structure to maintain the
third-party license:
Create a folder licenses under root to hold the licenses of the dependencies, like lib1.txt
with the content of lib1 license, and lib2.txt with the license content of lib2.

In your LICENSE file under root, you can use statement like "This project/module has a binary
dependency on lib1, with its license available in licenses/lib1.txt...". As long as you have
correct description about the relationship with the third-party library. It should be fine.

Again, for source code release, it is OK without saying the relationship and pointing to the
licenses, because users only grab your source code with the correct apache license 2.0. You
do not ship the libraries you depend on in your artifacts, but you can tell the users they
can download them from somewhere to run your project. After they download it, it is their
responsibility to get the correct dependencies, build and run your project. To me, no matter
what they do, how they use and build, are technically out of your scope, because it is not
under the brand of apache. Even if they run into legal issues, it will be their problems.


But for binary release, you need to say the artifact you ship depends on these these libraries
with the licenses, since the artifact is built based on them, and is made available under
the brand of apache.

This is actually my understanding about shipping the code and binaries.
 
Best wishes.

What Alex is saying makes sense. Whether you like it or not, you are creating a derived work
(or something - I am not a lawyer), and that needs its own L&N.

top-level LICENSE to make it convenient for someone to see what the ingredients are, because
some folks are "allergic" to certain licenses.  I think you can still use "pointers" instead
of copying full texts of licenses, but having people open jar files to read the licenses seems
to defeat the "convenience" of reading the ingredients.  If your packaging can extract a LICENSE
from each jar you could point to those files.
