将 .jar 转换为 .exe

Question

我创建了一个需要将 mail.jar 添加到类路径的项目...所以我做了它，在 IDE 作品中运行之后的所有内容... a

在我尝试使用 launch4j 编译带有自定义类路径的 .exe 文件后，我得到了这个输出：

所以我推断在构建过程中添加类路径时出错，尽管设置了类路径，但应该不会有人提示如何修复它

Launch4j 适用于 Windows 和 Linux/Mac。但是如果你运行宁 Linux/Mac，有一种方法可以将你的 jar 嵌入到一个 shell 脚本中来为你执行自动启动，所以你只有一个运行可用文件：

exestub.sh:

#!/bin/sh
MYSELF=`which "[=10=]" 2>/dev/null`
[ $? -gt  0 -a -f "[=10=]" ] && MYSELF="./[=10=]"
JAVA_OPT=""
PROG_OPT=""
# Parse options to determine which ones are for Java and which ones are for the Program
while [ $# -gt 0 ] ; do
    case  in
        -Xm*) JAVA_OPT="$JAVA_OPT " ;;
        -D*)  JAVA_OPT="$JAVA_OPT " ;;
        *)    PROG_OPT="$PROG_OPT " ;;
    esac
    shift
done
exec java $JAVA_OPT -jar $MYSELF $PROG_OPT

然后从您的 jar 创建运行可用文件：

$ cat exestub.sh myrunnablejar.jar > myrunnable
$ chmod +x myrunnable

它的工作方式与 launch4j 的工作方式相同：因为 jar 有一个 zip format，其中 header 位于文件的 end。你可以拥有任何你想要的 header（二进制可执行文件或像这里一样的 shell 脚本）和运行 java -jar <myexe>，因为 <myexe> 是有效的 zip/jar 文件.

将 .jar 转换为 .exe
