使用paxexam时测试使用mavenscrplugin创建的服务时遇到的java问题
我已经建立了一个非常简单的“HelloWorld”服务来演示我的问题。它使用maven scr插件生成服务描述符，并进行pax考试单元测试。但当我尝试运行“mvn clean test”时，它会阻塞一段时间，然后出现以下错误：
org.ops4j.pax.swissbox.tracker.ServiceLookupException: gave up waiting for service com.liveops.examples.osgi.helloworld.HelloWorldService
如果我运行“mvn-DskipTests=true package”，然后运行“mvn test”（不带clean） 它起作用了。区别似乎是在我的META-INF/M中增加了这一行 阿尼费斯特。MF文件：
Service-Component: OSGI-INF/com.liveops.examples.osgi.helloworld.internal.HelloImpl.xml
有人知道有没有办法确保在构建过程的早期添加这一行，以便“mvn清洁测试”通过？还是我可能做错了什么
以下是pom供参考。xml、服务和单元测试
