start /b /wait mvn clean install does not complete

I am trying to use the following commands to first generate my jar file and then copy it to a directory. Both these commands are in a batch file.

mvn -f mypathtofile\pom.xml clean install
xcopy mypathtojarfile\myjar.jar newpath\*.* /R /Y

What I found out was that my xcopy never happened because mvn takes some time to generate the jar file and that xcopy never waited until the mvn was done generating that file before starting. I realized this when I searched the destination directory and never found the jar file that was supposed to be copied over.

So then I did some research and found out that I might be able to use this:

start /b /wait mvn -f mypathtofile\pom.xml clean install
xcopy mypathtojarfile\myjar.jar newpath\*.* /R /Y

That's when I encountered the issue where mvn starts up correctly and generates the jar file but it never returns from that. Basically, my command prompt just pauses forever after the mvn finishes and never executes the next line in the batch file. This is what I see in the command prompt:

[exec] [INFO] BUILD SUCCESS
                                         [exec] [INFO] ------------------------------------------------------------------------
                                         [exec] [INFO] Total time: 1.997 s
                                         [exec] [INFO] Finished at: 2016-07-31T15:20:35-04:00
                                         [exec] [INFO] Final Memory: 18M/488M
                                         [exec] [INFO] ------------------------------------------------------------------------
                                         [exec]

Is there a way for mvn to to tell the command line that it finished its job?

In case mvn is a batch file (.bat or .cmd), you need to use call mvn ...... – aschipfl
That was what I needed. Thanks! – SpartaSixZero

@aschipfl Is there a wait command for call? – Travis Heeter
Well, there is no /WAIT option, call always waits for the called script or command to finish... – aschipfl

Try this code:

start "" /b /wait mvn -f mypathtofile\pom.xml clean install
xcopy mypathtojarfile\myjar.jar newpath\*.* /R /Y

Note that START command expects a window title, even if it runs with /b switch in the same window as your batch, and hence the start command title is empty.
