我生成 MSI 安装程序的过程如下。

  1. 运行mvn install生成Example-1.0-SNAPSHOT-jar-with-dependencies.jar.
  2. 运行windows-executable.bat生成Example-1.0.0.msi.
  3. 安装Example-1.0.0.msi.
  4. 转到安装目录,打开终端,然后运行Example-1.0.0.exe以查看阻止应用程序启动的任何错误。

此 POM 文件(已删除不相关部分)用于mvn install生成Example-1.0-SNAPSHOT-jar-with-dependencies.jar.

此脚本使用 jpackage 生成 MSI 安装程序。

mkdir temp
mklink "%~dp0temp\Example-1.0-SNAPSHOT-jar-with-dependencies.jar" "%~dp0..\..\target\Example-1.0-SNAPSHOT-jar-with-dependencies.jar"

"C:\Program Files\Java\jdk-14\bin\jpackage.exe" ^
--type msi ^
--app-version "1.0.0" ^
--copyright "Valkryst, 2020" ^
--name "Example" ^
--vendor "Valkryst" ^
--verbose ^
--icon "%~dp0..\..\res\icon\icon.ico" ^
--input "%~dp0temp" ^
--java-options "-Djdk.module.illegalAccess=permit" ^
--main-class "com.valkryst.Example.Driver" ^
--main-jar "Example-1.0-SNAPSHOT-jar-with-dependencies.jar" ^
--win-dir-chooser ^
--win-shortcut ^
--win-console

del "%~dp0temp\Example-1.0-SNAPSHOT-jar-with-dependencies.jar"
rmdir "%~dp0temp
pause

这是第 4 步的输出。

PS C:\Program Files\Example> .\Example.exe
Error: Could not find or load main class com.valkryst.Example.Driver
Caused by: java.lang.ClassNotFoundException: com.valkryst.Example.Driver

经过进一步调查,似乎 jpackage 实用程序不支持符号链接。它没有将其打包Example-1.0-SNAPSHOT-jar-with-dependencies.jar到可执行文件中,因此安装Example-1.0.0.exe的无法加载主Driver类,因为它不存在于安装目录中。

mkdir temp
copy "%~dp0..\..\target\Example-1.0-SNAPSHOT-jar-with-dependencies.jar" "%~dp0temp\Example-1.0-SNAPSHOT-jar-with-dependencies.jar"

"C:\Program Files\Java\jdk-14\bin\jpackage.exe" ^
--type msi ^
--app-version "1.0.0" ^
--copyright "Valkryst, 2020" ^
--name "Example" ^
--vendor "Valkryst" ^
--verbose ^
--icon "%~dp0..\..\res\icon\icon.ico" ^
--input "%~dp0temp" ^
--java-options "-Djdk.module.illegalAccess=permit" ^
--main-class "com.valkryst.Example.Driver" ^
--main-jar "Example-1.0-SNAPSHOT-jar-with-dependencies.jar" ^
--win-dir-chooser ^
--win-shortcut ^
--win-console

rmdir /S /Q "%~dp0temp
pause
