获得例外:
java.io.IOException:CreateProcess:\ output:C:\ InstallList.txt product get name,version error = 123 at java.lang.ProcessImpl.create(Native Method) 在java.lang.ProcessImpl。(未知来源) at java.lang.ProcessImpl.start(Unknown Source) 在java.lang.ProcessBuilder.start(未知来源) 在java.lang.Runtime.exec(未知来源) 在java.lang.Runtime.exec(未知来源) 在java.lang.Runtime.exec(未知来源) 在CmdExec.main(CmdExec.java:20)
答案 0 :(得分:1)
问题是您正在尝试将"/output:C:\\InstallList.txt product get name,version"
作为命令执行,但这不起作用。 (事实上,对我来说这看起来像是胡说八道。)
我希望你应该像这样执行命令:
rt.exec("wmic /output:C:\\InstallList.txt product get name,version");
