我正在阅读“OSGi and Apache Felix 3.0”这本书并遇到了一个问题,即我正在部署的软件包坚持认为它依赖于另一个软件包的错误版本。对于之前已经完成这些示例的任何人,我只是在第10章的末尾 - 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”的软件包,我刚刚添加了一些新的日志记录功能。此新功能将其置于版本1.10.0
我有另一个名为“Bookshelf Service Gogo commands”的软件包,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”软件包时,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)
“Bookshelf Service”套装当然是错误的版本。我想使用版本1.10.0。
如果我更新或强制框架使用版本1.10.0,那么“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“Bookshelf Service”。
根据pom.xml文件,依赖性确实适用于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使用1.7.0。
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。我不认为问题存在,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,而且一切似乎都匹配。
关于出了什么问题的想法,或者在哪里寻找这个问题的根源?

答案 0 :(得分:2)
好的,这已经晚了很多年,但我遇到了几乎同样的问题,跟着同一本书。事实证明,问题在于我打破了原始Bookshelf Service捆绑包的pom.xml中的Export-Package命令,从1.7.0到1.10.0版本。仔细检查一下 - &#39;实例&#39;命令说明已安装的未运行的软件包的问题,清单文件的内容,pom.xml中的内容等等。
