.jar 可在命令行中工作，但不能在 Windows 资源管理器中工作

我有一个 SWT 应用程序，我正在尝试为其创建可运行的 .jar；不幸的是，我似乎无法从 Windows 资源管理器运行它，因为我从 Java 虚拟机启动器收到一条错误消息：

“找不到主类 gui.MainWindow。程序将退出。”

但是，它将通过命令行运行

java -jar xxxxx.jar

我花了相当多的时间查看导致我以下问题的线程：

编辑清单文件切换，
通过 javaw.exe 的运行时版本

但均无济于事。

我正在 eclipse 中创建可执行的 .jar 文件（包括我引用的 swt 库），并且还尝试了 fat-jar 插件。同样，它将在 Eclipse 中运行内部，不会出现任何问题。

我无法承担 .bat 等解决方法或将其转换为 .jex

我有一种挥之不去的感觉，这取决于我在 64 位系统上，但是，我已经经历过 64 位和 32 位系统如前所述，javaw.exe 的位版本。

任何建议都非常受欢迎。

原文

I have an SWT application that I'm trying to create a runnable .jar for; unfortunately, I cannot seem to run it from Windows Explorer, as I get an error from the Java Virtual Machine Launcher stating it:

"Could not find the main class gui.MainWindow. Program will exit."

However, it will run through command line

java -jar xxxxx.jar

I have spent a considerable amount of time looking through threads that have lead me to:

edit the manifest file
switch through the runtime versions of javaw.exe

all to no avail.

I am creating the executable .jar file in eclipse (including my referenced swt libraries), and have also tried the fat-jar plugin.
Again, it will run inside of eclipse with no issues.

I cannot afford a work-around such as a .bat or turning it into a .jex

I have a nagging feeling it is down to me being on a 64-bit system, however, I have gone through both 64-bit and 32-bit versions of javaw.exe as previously stated.

Any suggestions would be more than welcome.
