Please include LICENSE file under META-INF/ in the release jars

[vlsi]

The current release jars miss META-INF/LICENSE.
For instance, see https://repo1.maven.org/maven2/com/google/guava/guava/31.1-jre/ -> guava-31.1-jre.jar

% unzip -l guava-31.1-jre.jar  | grep META-INF

The license requires to give a copy of the license when redistributing the software:

See https://www.apache.org/licenses/LICENSE-2.0
4.a You must give any other recipients of the Work or Derivative Works a copy of this License; and

Even though the jar file includes a link to http://www.apache.org/licenses/LICENSE-2.0.txt, the link is not a copy as the link might become inaccessible, so the recipients might fail to receive "a copy of the License".

I suggest including the license file as META-INF/LICENSE.

By the way, Google Guice does include the license (Apache-2.0) as META-INF/LICENSE: https://repo1.maven.org/maven2/com/google/inject/guice/5.1.0/

Just in case, here's the opinion of the Apache Software Foundation: https://issues.apache.org/jira/browse/LEGAL-642

Thanks, especially for the Guice reference. I haven't found any docs inside Google that speak directly to this, but I'll get this in place for Guava and some of the other libraries we're involved with.
