从 Flex for mac os 执行 Shell 脚本

Question

我在这里处理的是 NativeProcess，特别是 mac os 中的命令。所以，我在与我的应用程序相同的目录中有一个 .sh 文件。通过这个 shell 脚本，我正在尝试执行一个 .jarfile（同样的目录） .不知何故，我犯了一些错误，这就是它不起作用的原因。

我的代码是下一个

            ]]>
        </fx:Script>
    </s:WindowedApplication>

接下来是shell脚本部分

java -jar Test.jar

当我在 mac 系统上测试这个应用程序时，应用程序显示警告框（关于 .sh 文件路径），但接下来没有其他任何事情发生。

在使用 NativeProcesses 时没有什么可做的。如果您发现任何奇怪或错误的地方，请告诉我。

谢谢
