部署时所需的资源与 pom 中的说明不匹配

Question

我正在阅读《OSGi 和 Apache Felix 3.0< /a>”并且遇到了一个问题，我正在部署的捆绑包坚持认为它依赖于另一个捆绑包的错误版本。对于之前学习过这些示例的人来说，我刚刚完成第 10 章——在 Bookshelf Service Bundle 中实现日志记录功能。

基本上问题如下：

我有一个名为“Bookshelf Service”的捆绑包，我刚刚向其中添加了一些可爱的新日志记录功能。这个新功能将其置于版本 1.10.0

我有另一个名为“Bookshelf Service Gogo 命令”的捆绑包，它是“Bookshelf Service”中功能的命令行界面。它的版本是 1.9.0。

令人费解的是，当我部署“Bookshelf Service Gogo 命令”捆绑包时，它安装如下：

deploy -s "Bookshelf Service Gogo commands"

Target resource(s):
-------------------
Bookshelf Service Gogo commands (1.9.0)

Required resource(s):
---------------------
Bookshelf Service (1.7.0)

这当然是“Bookshelf Service”捆绑包的错误版本。我想使用 1.10.0 版本。

如果我更新或强制框架使用版本 1.10.0，则“Bookshelf Service Gogo 命令”提供的功能将不再可用。它拒绝使用最新版本的“书架服务”。

但根据 pom.xml 文件，依赖关系确实适用于 1.10.0 版本的“Bookshelf Service”。 “Bookshelf Service Gogo 命令”的 POM 如下：

所以我不明白为什么它只想与 1.7.0 一起使用。

还值得一提的是，这两个包都利用了 iPOJO，因此它们确实有 meta.xml 文件。然而，我认为问题不存在，因为我一直在将我的代码与书籍示例的可下载示例代码进行比较，并且一切似乎都匹配。

关于出了什么问题的任何想法，或者在哪里寻找这个问题的根源？

好吧，这已经晚了好几年了，但我刚刚遇到了几乎同样的问题，遵循同一本书。事实证明，问题是我在从 1.7.0 版本到 1.10.0 版本的过程中破坏了原始 Bookshelf Service 捆绑包的 pom.xml 中的 Export-Package 命令。仔细检查 - “instance”命令说明了已安装但未运行的捆绑包的问题、清单文件的说明、pom.xml 中的内容等。
