我试图通过在启动功能中添加事件管理和scr功能来构建自定义发行版。

我在http://karaf.apache.org/manual/latest/developers-guide/custom-distribution.html的官方文档基础上尝试了以下内容。

我使用以下pom.xml创建了一个新项目：

不幸的是，当我运行'mvn安装‘时，它失败了：

代码语言：javascript

[ERROR] Failed to execute goal org.apache.karaf.tooling:karaf-maven-plugin:4.0.4:assembly (default-assembly) on project jf-framework-karaf: Unable to build assembly: Unable to resolve root: missing requirement [root] osgi.identity; osgi.identity=scr; type=karaf.feature; filter:="(&(osgi.identity=scr)(type=karaf.feature))" -> [Help 1]

如果我将‘eventadmin’和'scr‘功能移到’引导特性‘(虽然这不是我最初希望的那样)，则可以组装自定义的karaf发行版，但是当我启动它时，它会返回一些异常，如下所示：

The specified feature: 'standard' version '4.0.4' is already installed
The specified feature: 'scr' version '4.0.4' is already installed
The specified feature: 'eventadmin' version '4.0.4' is already installed
^C
karaf@root()> ^Dkaraf@root()>

尽管一切都已安装并启动正常。在重新启动之后，所有的异常都会消失并正常工作。

我的问题是：

  1. 如何制作自定义发行版，其中事件管理和scr 功能在引导时启动(startup.properties)？
  2. 当在bootFeatures上设置事件管理/scr特性时，如何在第一次引导时消除这些异常？

顺便提一句，我已经能够设置一个稳定的自定义发行版，因为我希望使用废弃的旧样式的Maven程序集，但是使用karaf-maven-plugin的新方法似乎要容易得多。

从Karaf标准特性中删除运行时范围：

代码语言：javascript
复制
<dependency>
    <groupId>org.apache.karaf.features</groupId>
    <artifactId>standard</artifactId>
    <version>4.0.4</version>
    <classifier>features</classifier>
    <type>xml</type>
</dependency>

此范围防止将eventadmin/scr所需的某些包添加到启动阶段。tbh，我不清楚用于生成程序集的解析器的所有方面，这里使用的是不同的阶段和配置文件，但是删除这个作用域使其工作。
