我是 Java/Karaf 4.0.9/Maven/Pom/Camel 的新手，我无法解决问题
pom.xml文件中的Json部分，这里我改了很多Json version , 但没有用。
<dependency>
<groupId>org.json</groupId>
<artifactId>json</artifactId>
<version>20151123</version>
</dependency>
我在这里附上了我的 Pom.xml 文件，我用谷歌搜索了它。并得到 same issue in GSON但我不知道如何解决 felix 中的问题。

我该如何解决这个问题？
最佳答案
您的构建看起来很棒。据我所知，您生成了一个有效的 bundle 。
现在在运行时你必须提供你的项目依赖的所有包。错误消息告诉您您的包需要一个包 org.json。所以你需要安装一个 bunde 来导出这个包。
你可以试试这个包:
install -s mvn:org.json/json/20180813
您还应该考虑在构建期间创建一个功能文件，允许一次性安装您的代码，包括依赖项。
关于java - org.osgi.framework.BundleException : Unable to resolve: missing requirement: osgi. wiring.package; (osgi.wiring.package=org.json)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/55862916/
