使用 felix、osgi 和 PaxRunner 框架为 osgi 创建集成测试时出现 java.lang.AbstractMethodError/ClassCastException

Question

我正在尝试为我的捆绑包创建集成测试。基本上我想模仿我在普通网络应用项目中的设置（其中测试在 src/test 文件夹中）

我快到了，只是捆绑包尝试激活时出现异常

原生容器异常

我尝试向他们的官方 JIRA 委员会提交，但我无权这样做：

https://ops4j1.jira.com/browse/PAXEXAM/fixforversion/12880/?selectedTab=com.atlassian.jira.jira-projects-plugin:version-issues-panel

专家可以帮我解决我的问题吗？我已经走到尽头了:(

命令：mvn clean verify

Answer 1

您的类路径中似乎存在冲突的 OSGi Core API 版本。在运行时，您的 OSGi 框架（Felix 或 Equinox）应该是类路径上唯一的核心 API。

如果您有像 org.osgi:org.osgi.core 这样的其他版本作为（传递）依赖项，请确保将其指定为 provided 范围或排除该依赖项。
