我正在研究包含后端和前端的端到端项目。前端工作正常（angular2框架，'npm start'和'ng build'）。然而，当我运行从项目主文件夹“命令mvn干净安装”，它给了我一个错误，我不知道：无法执行目标org.apache.maven.plugins：maven-jar-plugin：2.6：jar
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-jar-plugin:2.6:jar (default-jar) on project frontend: Error assembling JAR: Failed to determine inclusion status for: .\frontend\pom.xml: The request is not supported. -> [Help 1] org.apache.maven.lifecycle.LifecycleExecutionException: ...
根据该项目主文件夹，我可以运行“MVN编译”成功，但不'mvn干净安装'。它显示上述错误消息的前端失败，后端跳过。
maven settings.xml是原始的。我有正确的Java Home设置。
你能帮我吗？
