Java POM 插件问题（无法解析 mojo org.codehaus.mojo:exec-maven-plugin 的配置）
Java POM plugin issue (Unable to parse configuration of mojo org.codehaus.mojo:exec-maven-plugin)
当我 运行 mvn package exec:java 时出现错误。可能我对 exec-maven-plugin 插件配置有问题。我正尝试在 Google 云平台应用引擎上 运行 这个演示，但部署总是失败。但是，如果我通过 mvm package 在 locale 上编译它，它可以正常工作，而且我可以 运行 在 locale 上毫无问题地应用程序。

你能帮我解决问题或我遗漏了什么吗？

删除空 <classpath/> 它不允许在 exec:java 目标中只接受字符串值，请参阅文档 exec plugin doc
另一件事是 micronaut 覆盖了项目有效 pom 中的 maven exec 插件参数部分，因此可能的解决方案是：
