java - 如何在树莓派上构建 maven 项目

Question

我有一个 JavaFx maven 项目，我在 Windows 10 机器上开发，但稍后将在具有最新 raspbian 操作系统的 Raspberry pi 4 上使用。我现在已经开发到我的应用程序的特定状态，现在想在我的 pi 上测试它。我在我的 pi 上安装了最新的 liberica Jdk 15，但我收到了一个我不明白的错误：

**OpenJDK Server VM warning: You have loaded library /home/pi/.openjfx/cache/15/libprism_es2.so which might have disabled stack guard. The VM will try to fix the stack guard now.
It's highly recommended that you fix the library with 'execstack -c <libfile>', or link it with '-z noexecstack'.
Loading library prism_es2 from resource failed: java.lang.UnsatisfiedLinkError: /home/pi/.openjfx/cache/15/libprism_es2.so: /home/pi/.openjfx/cache/15/libprism_es2.so: falsche ELF-Klasse: ELFCLASS64 (Possible cause: can't load AMD 64 .so on a ARM platform)

    ... 5 more

另一件事是，即使我安装了 liberica 并将其设置在我的项目中，如果我运行 java --version 我得到这个打印：

openjdk 15 2020-09-15
OpenJDK Runtime Environment (build 15+36)
OpenJDK Server VM (build 15+36, mixed mode)

有人可以告诉我我的错误是什么吗？

Answer 1

你是如何构建 .jar 的？

一些工具，例如 shade 插件不会创建跨平台 jar。

这将解释异常：can't load AMD 64 .so on a ARM platform
