Maven SCR插件-不生成OSGI-INF文件夹 [英] Maven SCR Plugin - Not generating OSGI-INF folder
问题描述
我在使SCR插件正常工作时遇到了麻烦.我进行了尽可能多的搜索，只找到了与我需要使用的结构不相似的示例.以下是POM的片段.这些几乎是CQ项目原型生成的默认值.所有依赖项都在那里，所以可能不是那样.这是构建的输出:
I have been having trouble getting my SCR plugin working. I have searched as much as I could bur only found examples that were not similar to the structure I am required to use. Snippets of POMs below. These are pretty much the default generated by the CQ project archetype. All dependencies are there, so it is probably not that. Here is the output of the build:
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

输出的关键部分是[INFO] --- maven-scr-plugin:1.7.4:scr (generate-scr-descriptor) @ project-bundle ---.看来，即使注释存在于类中，它也不会生成任何东西.
The key part of the output is the [INFO] --- maven-scr-plugin:1.7.4:scr (generate-scr-descriptor) @ project-bundle ---. It appears that it is not generating anything even though the annotations exist on the class.

非常感谢您的帮助.
推荐答案
我猜您正在使用<packaging>bundle</packaging>，如果是这样，我可以通过将org将maven-scr-plugin升级到1.9.0来解决此问题. apache.felix.scr.annotations @ 1.7.0
I'm guessing you're using <packaging>bundle</packaging>, if so I got this working by upgrading maven-scr-plugin to 1.9.0, with org.apache.felix.scr.annotations @ 1.7.0
我在这里放了一个工作版本的压缩包: https://dl.dropboxusercontent .com/u/2465717/com.stackoverflow.osgi.scr.tgz
I put a tarball of a working version here: https://dl.dropboxusercontent.com/u/2465717/com.stackoverflow.osgi.scr.tgz
注意:您可以启用Eclipse m2e生命周期映射-它运行良好(Juno SR2)，在正常的问题"控制台中生成SCR组件错误.将action <ignore/>更改为:
Note: you can enable the Eclipse m2e lifecycle mapping - it works well (Juno SR2), generating SCR component errors in the normal Problems console. Change the action <ignore/> to:
<action>
<execute>
<runOnIncremental>true</runOnIncremental>
<runOnConfiguration>true</runOnConfiguration>
</execute>
</action>
此外，虽然规范指出SCR运行时将搜索重载的de/activate方法-作为个人喜好，我将在相应方法上使用@ Activate，@ Deactive和@Modified来使意图明确(在代码和生成的XML中) .但是每个人都有自己的想法.
Also while the spec indicates the SCR runtime will search for overloaded de/activate methods - as personal preference I would use @Activate, @Deactive and @Modified on the respective methods to make the intent explicit (in code and generated XML). But each to their own.
