Apache Tomee 7.0.2 - 微服务的 Maven 编译错误

Question

我正在使用 Apache Tomee 7.0.2 微配置文件并尝试了解有关微服务的更多信息。教程链接之一位于https://www.javacodegeeks.com/2017/03/microservices-series-microprofile-apache-tomee.html。

使用上面链接中的示例，我在 Maven 打包阶段收到以下错误。

[INFO] --- tomee-maven-plugin:7.0.1:exec (default-cli) @ Microservice ---

我不太明白错误信息：

[ERROR] Failed to execute goal org.apache.tomee.maven:tomee-maven-plugin:7.0.1:exec (default-cli) on project Microservice: Execution default-cli of goal org.apache.tomee.maven:tomee-maven-plugin:7.0.1:exec failed: For artifact {io.microservices.tutorial:Microservice:0.0.1-SNAPSHOT:jar}: An attached artifact must have a different ID than its corresponding main artifact. -> [Help 1]

这是 pom.xml。

在此不胜感激。
谢谢。

你正在运行什么 Maven 命令？试试mvn clean package

还需要将<artifactId>javaee-api</artifactId> 标记为provided 范围，并且可能根本不应该包含jackson :)
