This layer provides support for the JVMs of the Eclipse Temurin Project for use with OpenEmbedded and/or Yocto Project build systems.
The process of building a JVM binary takes a long time and maintaining it (e.g. applying patches and testing it) is a lot of work. The Eclipse Temurin Project makes sure that the produced binaries pass the relevant Oracle Java Compatibility Kit (JCK), to demonstrate that the binaries are compatible implementations of the Java specification.
If you're using the Yocto Project's reference distribution called Poky, then you're already set up. Just add this layer to your build configuration. Please remember to use a branch that is matching with the Codename of your build. See https://wiki.yoctoproject.org/wiki/Releases for Codenames.
Each codename of OE/Yocto, that is supported by this layer, has a corresponding branch in this repository. See https://wiki.yoctoproject.org/wiki/Releases for a comprehensive list of Codenames.

Participation is welcome and endorsed by the chosen license and a simplified contributor agreement.
Please submit any patches against the meta-openjdk-temurin layer via pull requests on the project page on GitHub.
As the chosen open source license implicitly serves as both the inbound (from contributors) and outbound (to other contributors and users) license, there's no need for an additional contributor agreement.
But to be super safe, this project requires developers to state that each commit they make is authorized. A Developer Certificate of Origin requirement is how many projects achieve this.
By making a contribution to this project, I certify that:
a. The contribution was created in whole or in part by me and I have the right to submit it under the open source license indicated in the file; or
b. The contribution is based upon previous work that, to the best of my knowledge, is covered under an appropriate open source license and I have the right under that license to submit that work with modifications, whether created in whole or in part by me, under the same open source license (unless I am permitted to submit under a different license), as indicated in the file; or
c. The contribution was provided directly to me by some other person who certified (a), (b) or (c) and I have not modified it.
d. I understand and agree that this project and the contribution are public and that a record of the contribution (including all personal information I submit with it, including my sign-off) is maintained indefinitely and may be redistributed consistent with this project or the open source license(s) involved.
Therefore the contributors to this project sign-off that they adhere to these requirements by adding a Signed-off-by line to commit messages.
This is an example commit message.
