我需要从 Java 控制台应用程序运行此命令:
/usr/bin/java -Xms512m -Xmx3072m -jar /Users/ivan/Desktop/market/market.jar 500 500 1 1 0.1 true true /Users/ivan/Desktop/market/files/simulationResult/
我试过了,但没有用:
Process child = Runtime.getRuntime().exec(new String[]{command}); // command is the string written above
我尝试了很多其他的东西,但我没有得到它。有什么帮助吗?
顺便说一句,我正在使用 Mac(如果重要的话)。
编辑:使用上面的代码,我收到以下错误:
Exception in thread "main" java.io.IOException: Cannot run program "java -Xms512m -Xmx3072m -jar /Users/ivan/Desktop/market/market.jar 500 500 1 1 0.1 true true /Users/ivan/Desktop/market/files/simulationResult/": error=2, No such file or directory

... 3 more
编辑#2:我现在发送这个而不是字符串“command”:
String[] commands = new String[]{
"/bin/bash", "-c",
"\"/usr/bin/java -Xms512m -Xmx3072m -jar " + simulatorPath + " "
+ var1 + " "
+ var2 + " "
+ var3 + " "
+ var4 + " "
+ var5 + " "
+ var6 + " "
+ var7 + " "
+ var8 + " "
+ "\""
};
但我还是得到了/bin/bash: /usr/bin/java -Xms512m -Xmx3072m -jar /Users/ivan/Desktop/market/market.jar 500 500 2 1 0.1 true true /Users/ivan/Desktop/market : No such file or directory
。
child.waitFor()
返回数字 127。
