Maven exhibits strange behaviour from cmd windows 7
I am using maven in a project here at work and I've come up to a rather strange (at least for me) problem. When I do an: mvn package everything seems ok but the output of mvn disappears as soon as maven completes. To test it more I just did a: mvn --help and I could not see the output. As soon 开发者_JS百科as the command finishes the prompt is cleared. I am doing my work now using redirections: mvn package > out and then: type out in order to see the output. Any help would be greatly appreciated!
Thanx!
Solved: To whoever finds this useful. At the end of mvn.bat there was the line
cmd /C exit /B %ERROR_CODE%
which I had to comment out like this:
@REM cmd /C exit /B %ERROR_CODE%
Check if the MAVEN_TERMINATE_CMD is set to on. If it is unset it:
set MAVEN_TERMINATE_CMD=
Check that the mvn.bat script in maven's bin directory doesn't contain an exit command without the /b option. It should end with the following line:
cmd /C exit /B %ERROR_CODE%
If neither alternative solves your problem, set the MAVEN_BATCH_PAUSE variable to on:
set MAVEN_BATCH_PAUSE=on
before you run maven. This should cause mvn.bat to wait for a keystroke before exiting.
The following is an example of how to use mvn in a batch file under Windows 7 and Maven 3.2.1
:: ensure variables do not propagate outside this batch call
setlocal
:: save current directory and change to ".."
pushd ..
:: tell mvn.bat to exit after done, not to spawn cmd (why is this by default..)
set MAVEN_TERMINATE_CMD=on
:: spawn new cmd prompt to handle the mvn call, which blocks and exits
cmd /c mvn clean install
:: do something fancy here
:: cd to saved directory (pushd)
popd
:: pause the script and require pressing a key to continue
pause
