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

Question

卡拉夫上来的时候我犯了以下错误：

安装startup.properties中列出的包时出错，url-mvn:org.apache.karaf.service/org.apache.karaf.service.guard/3.0.6=10

startup.properties的内容如下：

知道什么是理由吗？

Answer 1

在etc/startup.properties中指定的所有URI（带有schememvn:)在启动时由Karaf直接翻译。

实际上不可能解析mvn:URI，因为mvn\:org.ops4j.pax.url/pax-url-aether/2.4.5包是可以执行这种解析的包，在这里我们会遇到鸡蛋问题。

因此，Karaf将这些mvn:URI转换为指向${Karaf.home}/system的file:URI。例如mvn\:org.ops4j.pax.logging/pax-logging-logback/1.8.4文件：${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。请确保在Karaf的system/目录中有org.apache.karaf.service.guard-3.0.6.jar包。
