我正在尝试升级我的项目设置以在 Java 11 和 Sling 11 上运行。为此，我一直在尝试将我的 Maven 编译器升级到 3.8.0，但这似乎导致 maven-scr-plugin 出现问题；使其无法扫描仅包含枚举的简单类。

尝试构建 Maven 项目时遇到的错误如下：

    [ERROR] Failed to execute goal org.apache.felix:maven-scr-plugin:1.26.0:scr (generate-scr-scrdescriptor) on project foo-forms.core: {file location} : Unable to scan class files: {package.foo.class} (Class file format probably not supported by ASM ?): IllegalArgumentException -> [Help 1]

这是我的大部分 POM 文件（已删除敏感信息）：

我已经进行了一些故障排除，我的理解是 scr-plugin 根本不支持最新的 maven-compiler，因为一个比另一个早几个月发布（参见下面的链接）：

maven-scr-插件

maven 编译器插件

我想知道是否有人遇到过类似的问题并想出了一些解决方法。谢谢！

通过迁移到 Java 11，您创建的类文件将被编译为 Java 11 字节码。然后maven-scr-plugin必须扫描此字节码以找到应用于它的注释。除非您能找到maven-scr-plugin支持 Java 11 字节码的版本（我不知道有一个），否则您将需要找到一种替代方法来创建您的声明式服务元数据。

一种选择是开始使用bnd-maven-pluginormaven-bundle-plugin和标准的声明式服务注释，而不是自定义 Felix 注释。请注意，这仍然涉及将这些插件更新到可以支持 Java 11 的版本。我相信bnd-maven-plugin版本 4.1.0 应该与 Java 11 一起正常工作......

解决方案是迁移到 bnd-maven-plugin，它是 maven-bundle 插件的超集。它拥有更好的开发人员基础，并且也将在未来的 Java 版本中得到维护。

AEM-acs-commons 和最新的 maven 架构类型（本回答时为 23）也已移植到 bnd 插件。
