Karaf 安装带有 url 的 startup.properties 中列出的 OSGi 包时出错

Question

Karaf 出现时出现以下错误：

使用 url 安装 startup.properties 中列出的捆绑包时出错 - mvn:org.apache.karaf.service/org.apache.karaf.service.guard/3.0.6 = 10

startup.properties的内容如下：

知道可能是什么原因吗？

Answer 1

etc/startup.properties 中指定的所有 URI（使用方案 mvn:）都由 Karaf 在启动时直接翻译。

实际上解决mvn: URI 是不可能的，因为mvn\:org.ops4j.pax.url/pax-url-aether/2.4.5 捆绑包是可以执行这种解决方案的，我们在这里会遇到鸡与蛋的问题。

因此，Karaf 将这些 mvn: URI 转换为指向 ${karaf.home}/system 的 file: URI。例如mvn\:org.ops4j.pax.logging/pax-logging-logback/1.8.4 → file:${karaf.home}/system/org/ops4j/pax/logging/pax-logging-logback/1.8.4/pax-logging-logback-1.8.4.jar。

如果未找到，则未解决。请确保您在 Karaf 的system/ 目录中拥有捆绑包org.apache.karaf.service.guard-3.0.6.jar。
