Please clarify license for the published artifacts

native-platform project publishes a lot of jar files, however they do not mention which license is in place.

1) Please add `Bundle-License: Apache-2.0` manifest entry (where `Apache-2.0` is SPDX identifier, see https://osgi.org/specification/osgi.core/7.0.0/framework.module.html#framework.module-bundle-license )
Well, current `pom.xml` tags are quite obvious (even though you might want to replace `` with SPDX id of `Apache-2.0`), however adding explicit `Bundle-License` would simplify automatic analysis.

2) Please add LICENSE file to the produced jar files.
The suggested file locations is `META-INF/LICENSE`

3) You might want to mention the license in `pom.xml` via `` tag, however it is not that required.
