我和我的同事正在尝试建立一个Yocto OS映像。我们的应用程序由几个用Java 17编写的微服务组成，它们需要在嵌入式设备（phyCORE i.MX 8M Plus Setup Guide）上运行。在另一个系统上，我们会在Docker容器中运行它们并以这种方式部署它们，但由于我们之前没有人在Yocto构建上工作过，我们有点陷入了让事情工作并找到我们必须添加到Yocto构建的层。
我们确实安装了meta-java layer，但它只基于openjdk-8。
以下文件是当前的生成配置

我们还尝试创建和添加一个包含openjdk-17的自定义层，但在do_configure()部分中通过bitbake <recipe-name>启动的交叉编译过程中失败。
是否有任何现有的层，我们可以添加使用一个新的Java版本比版本8或有任何提示，如何获得一个自定义层运行？
