Maven: multiple builds from cmd file

This is just a followup on/refinement of my previous post. This cmd/bat Script focuses on clean-build-installing multiple projects from a single script. This script halts at the first build failure. If you happen to run from window explorer by doble clicking the script, In case of error the command window stays open (Press any key to continue). If ever build was successful, the window closes automatically. In the following example, I am skipping the test execution for third project you can add/remove -DskipTests=true to any mvn calls.

REM Uncomment following if you want to clean local repo on each run
REM rmdir /S /Q "%HOMEPATH%\.m2\repository\com\mygroup\id"

call mvn -f ProjectA\pom.xml clean install
if not "%ERRORLEVEL%" == "0" goto error

call mvn -f ProjectB\pom.xml clean install
if not "%ERRORLEVEL%" == "0" goto error

call mvn -DskipTests=true -f ProjectC\pom.xml clean install
if not "%ERRORLEVEL%" == "0" goto error

exit

:error
@echo Build Failed
pause


Hope you find this helpful.

Calling multiple bat files from a bat file

Earlier I had posted about closing command window that is left open after executing a bat file. This post is about calling multiple bat files from a bat file.

Today, while trying to execute multiple maven builds from a bat file, I observed that only first build one was called and once the first build was over, the execution stopped. Next builds were not called at all. I Did some search and found this. Yeah mvn command is a bat file, I knew that. What i missed was putting a call before the mvn commands:

cd ProjectA
call mvn install
cd ..

cd ProjectB
call mvn install
cd ..


The post linked above goes one level further by checking the %ERRORLEVEL% and exiting the script if any any build fails.

So lesson learnt today :
If you need to call multiple bat files from a bat file, start each bat command with a call

Google Code adds Git support

Git finally makes it to the Google's code hosting platform. Git happens to be third Version Controlling System supported on
Google Code, following Subversion and Mercurial.

The announcement states:

Since our original announcement of Mercurial support, Git has grown significantly more popular and user-friendly, and on the technical side, it has added an efficient “smart” HTTP protocol that fits with Google’s HTTP-based infrastructure. (Note that this feature is only available in version 1.6.6 and later.)

This is very welcome addition as Git's popularity is increasing exponentially but I am not sure how many people will actually switch to Google code for Git hosting as more open source git projects are already using trendy and hep Github. Github is more social too. This is certainly going to help those who already have projects hosted on Google Code and want to switch to git.

I personally like mercurial slightly more than git for its simplicity. Git, for novice, is overwhelming. Whatever your choice may be, Distributed Version Controlling Systems have started taking over and are becoming mainstream. If you are still unsure about what it all means, don't worry, you are just git init / hg init away.
