Output files:
library: C:\Users\shubh\Documents\Altova\MapForce2017\MapForceExamples\Tutorial\library.xml
Execution successful.

Answer 1

我建议使用https://commons.apache.org/proper/commons-exec/用于从 Java 内部执行 o/s 命令，因为它处理您以后可能遇到的各种问题。

您可以使用:

CommandLine cmdLine = CommandLine.parse("cmd /c d: && cd MapForceServer2017\\bin\\ && mapforceserver run ...");
DefaultExecutor executor = new DefaultExecutor();
int exitValue = executor.execute(cmdLine);
