使用 url 安装 startup.properties 中列出的 OSGi 包时出现 Karaf 错误

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内容如下：

知道是什么原因吗？

Answer 1

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

实际上解析 mvn: URI是不可能的，因为mvn\:org.ops4j.pax.url/pax-url-aether/2.4.5 bundle是可以执行这种解析的那个，我们会有先有鸡还是先有蛋的问题这里。

所以 Karaf 将这些 mvn: 个 URI 翻译成 file: 个指向 ${karaf.home}/system 的 URI。例如 mvn\:org.ops4j.pax.logging/pax-logging-logback/1.8.4 → file:${karaf.home}/system/org/ops4j/pax/logging/pax-logging-logback/1.8.4/pax-logging-logback-1.8.4.jar.

如果没有找到，则未解决。请确保您在 Karaf 的 system/ 目录中有 org.apache.karaf.service.guard-3.0.6.jar 包。
