OSGi：如何在包装器包中嵌入依赖项

问题描述

我们想在我们的 AEM 项目中使用 google-maps-services。为了能够在OGSI环境我创建嵌入罐子及出口com.google.maps包的封装包来使用它。 遗憾的是，bundle 无法启动，因为它缺少以下依赖项：

• com.google.appengine.api
• io.opencencus.stats
• io.opencencus.tags
• okhttp3
• okio

我也尝试嵌入它们，但由于某种原因，这似乎不起作用。

我做错了什么？

解决方法

经过多次尝试和错误，我发现了缺失的部分。您还需要导出其他依赖项：
Export-Package: io.opencensus.tags,io.opencensus.stats,com.google.appengine.api.urlfetch,okhttp3.*,okio.*com.google.maps.*

并且您需要为运行时导入它：
Import-Package: javax.net.*;version=0.0.0
