Java 作为JPackage安装的一部分，如何在linux中使本机linux应用程序可执行

我正在使用JPackage（Java14）为linux打包一个Java应用程序（称为Jaikoz）

java应用程序有时必须调用名为fpcalc64的c程序，在安装时它会存储在app文件夹中，但它只有rw权限

问题1

作为安装的一部分，我有没有办法授予它执行权限

问题2

即使我手动进入应用程序文件夹并使用

chmod 777 fpcalc64

授予完全执行权限，它仍然没有运行，我的Java程序抱怨它没有权限，即使我重新启动应用程序，这种情况仍然会发生，这怎么可能

e、 g

失败

但是如果我从LinuxShell运行，它可以工作

问题3

我是否必须将fpcalc64存储在bin文件夹中，而不是lib/app中。如果我这样做了，我该怎么做，它是一个预编译的二进制文件？

我找到了解决方案（我以前遇到过）

因为Java 9在linux上使用Java调用外部应用程序时使用

lib/jspawnhelper

来决定如何运行应用程序。因为我提供了linux运行时，但在将运行时签入源代码管理时它是在Windows上构建的，所以它失去了任何执行权限。因此，当我的应用程序抱怨权限时，它实际上是在抱怨jspawnhelper上的权限

我还发现，如果您确实设置了权限，那么在构建包时将尊重这些权限。我没有意识到这一点，因为之前我在Windows上构建linux安装程序，必须向Izpack安装程序添加额外的命令以使其可执行

总之，解决方案是在jspawnhelper和fpcalc上设置执行权限并提交到源代码管理，然后

Jpackage

就可以工作了。
