Bat script exits unexpectedly

Question

I have the following bat script:

@echo off set JAVA_HOME=C:\Program Files\Java\jdk1.6.0_32 set JRE_HOME=C:\Program Files\Java\jdk1.6.0_32\jre set Path=%JAVA_HOME%\bin;%Path% cd C:\project mvn validate compile package db-migration:migrate -DskipTests REM script exits here, the second line never been executed java -jar target/compiled_tar.jar

The last line never been executed. The "mvn..." is successfully done, the compiled_tar.jar is created, the output is:

[INFO] BUILD SUCCESS

If I insert the PAUSE command between last and previous lines the PAUSE also never been occurred. Why?

mvn might be quitting the entire process. I've had the same problem with some ant directives in the past, hope to see a solution as well. — TheZ

Could do mvn … && true I think cmd may not have a true command see have to replace with echo. (almost the same, but prints a blank line). The trouble with this is you don't know if there was an error. What are the error codes for mvn? — ctrl-alt-delor

Possible duplicate of Why does only the first line of this Windows batch file execute but all three lines execute in a command shell? - it is even the same BAT file, "mvn". — Peter Mortensen

mvn is itself a .bat file, so (for compatibility with MS-DOS 1.0) Windows will stop executing your batch file. To fix this, use the call command:

call mvn validate compile package db-migration:migrate -DskipTests

You have changed my life. Thanks!

The year is 2013 and I have to care about how MS-DOS 1.0 functioned 32 years ago. I don't know whether I should be sad or impressed.

Using this Maven command (set maven_batch_pause=on) will solve this perfectly:

@echo off set JAVA_HOME=C:\Program Files\Java\jdk1.6.0_32 set JRE_HOME=C:\Program Files\Java\jdk1.6.0_32\jre set Path=%JAVA_HOME%\bin;%Path% set maven_batch_pause=on cd C:\project mvn validate compile package db-migration:migrate -DskipTests REM The script exits here, and the second line will never be executed java -jar target/compiled_tar.jar
