【问题描述】：
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，但这似乎导致了 maven-scr-插入;使其无法扫描仅包含枚举的简单类。
我在尝试构建 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）：
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！

使用 maven bundle 插件和更新的 osgi r6 注释。 maven scr 插件已经维护多年了
