令人费解的是 3 周.. 所以我知道 jlink、jdeps 和 jpackage 相当好.. 但不知道 jpackage 如何在内部工作，在这种情况下是 Mac ......但我也在 Win10 和 Win 10x64 openjdk/fx 环境中得到同样的交易..我已经用尽了这个谜题中的所有（我认为）红鲱鱼。，

所以 jar 在 openjdk15 bin 目录中运行良好.. 但是当我 jpackage 并打开安装 mac 应用程序（在 pkg 安装之后）.. 然后我收到有关缺少模块的投诉（好像它可能会遇到一个 xcode old jre 或在我构建的运行时或路径上的 jdk .. all openjdk 15.0.1 上到达 jdk 之前的东西。

所以它是 jpackage 在内部构建的可执行内容中所做的事情，它没有正确调用 jar（即使我不使用 jlink 和 jpackage 它只是添加模块用于 fx jmods 命中路径 mvn jdk .. 也是 openjdk15.0.1）

jpackage 在评论中..

jdeps..

./jdeps --print-module-deps --ignore-missing-deps /Users/johnallen/Downloads/input/modsim-1.0-SNAPSHOT.jar
java.base,java.compiler,java.desktop,java.instrument,java .management,java.naming,java.scripting,java.security.jgss,java.security.sasl,java.sql,jdk.jfr,jdk.unsupported

当我确实构建了一个运行时..

 ./jlink --output /Users/johnallen/Downloads/jd15fx15modsimruntime-mvn-ver --module-path /Users/johnallen/Downloads/javafx-jmods-15.0.1 --add-modules javafx.controls,javafx.fxml,java.base,java.compiler,java.desktop,java.instrument,java.management,java.naming,java.scripting,java.security.jgss,java.security.sasl,java.sql,jdk.jfr,jdk.unsupported

当然作为 jdk15.0.1 文件夹中的 .jar 调用运行得很好

./Users/johnallen/downloads/jdk-15.0.1.jdk/Contents/Home/bin/java --module-path /Users/johnallen/Downloads/javafx-sdk-15.0.1/lib --add-modules= javafx.controls,javafx.fxml -jar /Users/johnallen/Downloads/input/modsim-1.0-SNAPSHOT.jar
