当在 MacBook Pro 上开发和部署时，该应用程序继续部署到桌面和 iphone，并且之前部署在 ubuntu 19-10 桌面上。所以我假设库或脚本更改阻止了 Ubuntu 20-04 上的应用程序部署。为了演示我构建并尝试运行https://docs.gluonhq.com/client/中描述的 HelloWorld 应用程序的问题。这个简单的应用程序不在 Ubuntu 20-04 上部署或运行，但在 MacBook Pro 上部署。
我当前的 Ubuntu 20-04 环境是：
Apache Maven 3.6.3
Maven home: /usr/share/maven
Java version: 11.0.6, vendor: Oracle Corporation, runtime: /home/linuxlp/opt/graalvm/graalvm-svm-linux-20.1.0-ea+28
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "5.4.0-31-generic", arch: "amd64", family: "unix"
该应用程序是：
package hello;
public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello World!!");
System.exit(0);
}
}
应用程序 maven pom.xml 是：
