如何在构建快照时添加JavaFXSDK

我正试图从我的Javafx项目中抓拍一下。我正在学习如何创建快照，所以我对它的工作原理不太了解。我目前正在snap.yaml中使用ant进行构建，但是当我运行snapcraft命令时，我得到一个错误，即它在我自己的系统中的目录中找不到JavaFXSDK

我的问题是如何添加sdk，使其始终随snap的安装一起提供，或者我可以以某种方式以更好的方式构建此项目

错误

compile.module.apptest.production:
    [mkdir] Created dir: /root/parts/my-part/build/out/production/appTest
    [javac] /root/parts/my-part/build/module_apptest.xml:96: warning: 'includeantruntime' was not set, defaulting to build.sysclasspath=last; set to false for repeatable builds
    [javac] Compiling 2 source files to /root/parts/my-part/build/out/production/appTest

BUILD FAILED
/root/parts/my-part/build/module_apptest.xml:96: /home/issenisse/Downloads/javafx-sdk-15.0.1/lib does not exist.

Snap.yaml

我最后尝试的是在构建时添加openjfx
