如何使用 Maven 插件将 jar 部署到 Raspberry Pi 2
How to Deploy a jar onto Raspberry Pi 2 using Maven Plugin
我有一个简单的 java class 使用包含主要方法的 Pi4J。我想构建它并将其部署到 Raspberry Pi。我在 windows 10 上使用 java 8,我的 IDE 是 NetBeans 8.1。如果项目设置为普通(非 Maven)Java 应用程序并设置为通过 NetBeans 构建配置部署到 Raspberry Pi,如 here 所示,项目将构建正常和 FTP 在罐子上然后 运行 它没有问题。
我想做同样的事情,但使用 Maven。问题是正在 运行 的代码具有 ARM 的 Pi 架构原生的 C 代码,而我正在使用的 Maven 插件似乎首先 运行 我本地盒子上的 jar,其中C 代码将崩溃并抛出 Exception
SEVERE: Unable to load [libpi4j.so] using path: [/lib/libpi4j.so]
java.lang.IllegalArgumentException: The path has to be absolute, but found: \lib\libpi4j.so

如果我只是做一个干净的构建,它会很好地构建并创建 jar。但是,如果我选择 运行 构建,那么这就是崩溃发生的地方。这是我用来将 jar 部署到 Pi 的 Maven 插件。

我正在尝试弄清楚如何更改此插件,使其不首先在我的本地计算机上执行代码。我只是想让它假定 jar 已构建,ssh 到远程 Pi 并将 jar 复制过来,然后 运行 它在那里。此外,如果有人在使用 Maven 时有更好的方法,那么我愿意接受建议。任何帮助都会很棒!

提前致谢。
已解决:此 pom 文件将构建 Pi4J 示例用例的可执行 JAR。然后它将 JAR 传输到 Raspberry Pi 然后执行它。在 netbeans 中,这是通过构建命令完成的。因此,一键构建、部署和 运行!
我不喜欢的一件事是它以包而不是原始 JAR 的形式带来依赖项。它还在构建时创建了 2 个 JAR;一种有依赖性,一种没有依赖性。打开 Jar,看看可以做些什么来改善结构。欢迎优化和反馈。
此外,为了简单起见,我将我的 RASPBERRY PI PROPERTIES 放在这个 pom 文件中。但是,这些应该位于 settings.xml 文件或其他文件中的受控用户主目录中。
注意:Pi4J 具有 C 代码原生 ARM 依赖项,这会阻止它 运行 在非 ARM 架构上运行,并且必须发送到 Pi。
