java - 不生成OSGI-INF文件夹

Question

我是 OSGI 新手。在生成的 jar 文件中获取 OSGI-INF 文件夹时遇到问题。 我需要如下所示的文件夹结构

• 元信息
• OSGI-INF
• Com.mine.cq

我正在使用 Eclipse 和 m2e 插件。当我运行我的项目时，我正在获得成功。我在生成的 jar 文件中得到了以下文件夹结构。

• 元信息
• Com.mine.cq

这是我的 POM.xml

为什么OSGI-INF文件夹不在.jar文件中？我需要在 OSGO-INF 文件夹中设置一些信息，因为我必须将我的组件注册为 OSGI 服务。 请指导我完成它。

Answer 1

虽然已经很晚了，但我会发布关于这个问题的 2 美分，以供将来引用。

正如已经指出的，如果您按照 Maven bundle plugin documentation 中给出的说明进行操作，则可以将 bundle 的“打包”设置为“jar” .

有一个小问题:使用该配置，您需要显式添加 <exportScr>true</exportScr>在插件配置中，以便正确创建 SCR xml 文件(还记得调整 list 位置，因为在文档中缺少该部分!)。

您可以在这里看到一个示例(这与您的完全不同，但我假设您可以轻松地在代码中减少它，如果您仍然感兴趣的话):
