Importing Projects and Building workspace from batch file - eclipse

Question

I have this batch file
#ECHO OFF
ECHO Please Enter Path of the View, you want to update in double quotes.
SET /P variable=
SET ECLIPSE=C:\Users\gdeep\Desktop\TED-4.3.0.20110512190809.lnk
SET WORKSPACE=C:\Users\gdeep\DevCodebase_2
:LOOP
ECHO Press 'g' for Graphical Interface and 'c' for Command line.
SET /P answer=
IF /I "%answer%"=="g" GOTO GRAPHICAL
IF /I "%answer%"=="c" GOTO COMMANDLINE
ECHO Invalid Input. Please Try Again.
GOTO LOOP
:GRAPHICAL
cleartool update -graphical %variable%
GOTO CONTINUE
:COMMANDLINE
cleartool update %variable%
GOTO CONTINUE
:CONTINUE
FOR /D %%i IN (%WORSPACE%) DO RD /S /Q "%%i" DEL /Q "%WORSPACE%\*.*"
START %ECLIPSE% -data %WORSPACE%
D:
chdir "%variable%"\v4electronics
ECHO Please Ensure that Server is killed.
PAUSE
mvn clean install -Dmaven.test.skip=true -Dresource.minify.skip=true
For deleting all the projects i used
FOR /D %%i IN (%WORSPACE%) DO RD /S /Q "%%i" DEL /Q "%WORSPACE%\*.*"
Can anyone explain this to me? I copied it from somewhere and don't want to use it without understanding.
Problem with using above command is althout it seem to work, i see
The system cannot find the file specified.
The system cannot find the path specified.
as the output.
Also, the way i am deleting, will it be equivalent to if i delete them from the eclipse, by select all projects and deleting?
Another problem here is that when i have .
mvn clean install -Dmaven.test.skip=true -Dresource.minify.skip=true
in the end it works fine, otherwise, if there is any other command after it, those commands doesn't run.
After this, I then wanna import all maven projects from the Clearcase %Variable%.
And i want to do that by command line only. Can you help me with that?
Thanks for your help.
Appreciate your time.

Answer 1

Please correct me, If I'm wrong. I understand that you're in the MS-Windows environment.
Regarding to the question about if there is another command after the "mvn ...", they are ignored.
I use the "call" as the following: -
cd project1
call mvn clean install
cd project2
call mvn clean install
I hope this may help.

cleartool update -graphical %variable%
This will update a view, opening a GUI during the update (if -graphical is used) for displaying the number of files unchanged, new, modified, deleted or hijacked during this update.
See cleartool update man page.
The graphical update will let you specify how you want hijacked files and timestamps handled by said update:
Click the Advanced tab and change default options for the Update Tool.
If you need to resolve hijacked files, select a method. You have these choices:
Leave hijacked files in place
Rename the hijacked files and load the selected version from the VOB
Delete hijacked files and load the selected version from the VOB
You can also select a method for handling timestamps. You have these choices:
Set file times to current time
Set file times to version creation time
You need to enter the path of the root directory of a snapshot view: see "To update snapshot views"
FOR /D %%i IN (%WORSPACE%) DO RD /S /Q "%%i" DEL /Q "%WORSPACE%\*.*"
This will completely empty Eclipse workspace, projects and its .metadata folder, forcing Eclipse to recreate a workspace from scratch.
It seems a bit extreme, and would basically be the same as
RD /S /Q "%WORSPACE%"
(Eclipse would recreate "%WORSPACE%" when launched with -data %WORSPACE%)
