Subject [jira] [Commented] (LEGAL-177) About using third-party software under GPL
Date Tue, 10 Sep 2013 05:27:55 GMT

    [ https://issues.apache.org/jira/browse/LEGAL-177?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13762746#comment-13762746

Kevan Miller commented on LEGAL-177:
------------------------------------

As long as the JFlex is a build-time dependency, agreed that there is no issue using JFlex.
Under the current license, distribution of JFlex would be another matter, entirely.

Sebb has quite correctly identified the foundation documentation for generating LICENSE and
NOTICE files.

If there are specific questions regarding how Apache MRQL should follow these guidelines,
we can field those questions here (or on the mailing list) -- although the MRQL project's
mentors and Apache Incubator should be well equipped to answer the questions, also...

If there are problems with the guidance provided by http://www.apache.org/dev/licensing-howto.html,
then I suggest these issues should be discussed/resolved on mailing lists or Jira's specific
to these problems.

> Apache MRQL (incubating) is planning to release its first release soon and we want to
check if the third-party software that we use has compatible licenses. Our current NOTICE
file is included below. My question is about JFlex and maven-jflex-plugin. They both have
Gnu GPL licenses which are not compatible with Apache License 2.0. But JFlex license indicates
"The code generated by JFlex inherits the copyright of the specification it was produced from.
If it was your specification, you may use the generated code without restriction." We simply
use JFlex to generate code (scanners). Can we use this software in MRQL?
