小贝子编程

部署时所需的资源与 POM 中的说明不匹配



我正在浏览"OSGi和Apache Felix 3.0"一书，遇到了一个问题，即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。对于以前处理过这些示例的任何人，我刚刚结束了第 10 章 - 在书架服务包中实现日志记录功能。

基本上问题如下：

我

有一个名为"书架服务"的捆绑包，我刚刚在其中添加了一些甜蜜的新日志记录功能。此新功能将其置于版本 1.10.0

我还有另一个叫做"书架服务Gogo命令"的捆绑包，它是"书架服务"中功能的命令行界面。它的版本为 1.9.0。

令人费解的是，当我部署"书架服务 Gogo 命令"捆绑包时，它的安装方式如下：

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"书架服务"捆绑包的错误版本。我想使用 1.10.0 版。

如果我更新或强制框架使用版本 1.10.0，则"书架服务 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"。

不过，根据pom.xml文件，该依赖项确实适用于1.10.0版本的"书架服务"。"书架服务 Gogo 命令"的 POM 如下所示：

所以我不明白为什么它只想使用 1.7.0。

还值得一提的是，这两个捆绑包都利用了 iPOJO，因此它们确实有 meta.xml 文件。但是，我认为问题不在那里，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，或者在哪里寻找这个问题的根源的任何想法？

好吧，这已经晚了好几年了，但我只是遇到了几乎相同的问题，按照同一本书。事实证明，问题是我在从 1.7.0 到 1.10.0 版本中破坏了原始书架服务捆绑包的 pom 中的导出包命令.xml。仔细检查 - "instance"命令说明了未运行的已安装捆绑包的问题，清单文件的内容，pom.xml中的内容等。
