Can I use apache 2.0 licenced software in my GPLv2 (or later) Plugin? (4 posts)

    I have searched and read a hell of a lot on this, but still I am confused.

    If I understand right Apache 2.0 Software can be included in GPLv3 but NOT in GPLv2.

    Am I right that plugins that I want to be listed on wp.org must be "GPLv2 (or later)" this means they cant be GPLv3 only means I cant use Apache 2.0 software in my plugin?

    It now clarifies that I can use GPL v3 code in a plugin without any issue.

    But you can’t host it in the WordPress plugin repository. And it couldn’t be pulled in to WordPress core. I’d recommend that you license plugins as “GPL” or “GPL version 2 or later” for maximum compatibility.

    Is is right that plugins mostly get accepted without really checking. They only get shut down if somebody complains? I have seen this.

    And If I am right about this: There is a plugin that contains Apache 2 code but says in every file that its GPLv2 Licenced without the "or later" and even with this it would not be legal because GPLv2 is not compatible with Apache 2.0 ??

    I really hope that I am wrong because else this would be really annoying.

    Yeah thanks, after reading this I think I have already read and forgotten this and got confused with some obviously outdated comment ;)

    Hi, sorry for re-using the topic, but my question is pretty related to this:

    I'd like to use parts of the google-php-api-client (http://code.google.com/p/google-api-php-client/), which is licensed under Apache 2.0, so just to confirm, can I use them in my "GPLv2 or later" plugins (I have in mind a free and a paid version)?

    I just wanted to make sure in order not to make WP/big G people upset :-)

    Thanks for your help!
