Call ant from batch file

I want to call ant from a batch file.
#echo off
cmd.exe /k cd /d E:\work\CRM
call ant
It's not working. Nothing is happening; neither showing any error nor nothing... How do I call ant?
I need to execute ant compile command from batch file from the current location E:\work\CRM.
Also I set the environment variables for ant:
ANT_HOME
JAVA_HOME

Get rid of cmd.exe /k since you're already in a batch file context
Add -d after ant to show debugging info

How to run a batch command in java files without actually going to the batch file?

So, it might be a noob question but am still stuck with it. I have a batch command in a batch file as:
#echo off
start "" /D "C:\UpworkUP" upwork.exe --args -url=chrome://crash -disable-web-security -script-url=https://172.27.68.6/pre_alpha/
My doubt is how do I run this command from java itself without calling the batch file here. So per say, I do not want the batch file, I just need to run the command in it from java directly.

Making a batch file showing how arguments are being parsed.
#Echo %1
#Echo %2
#Echo %3
#Echo %4
#Echo %5
#Echo %6
#Echo %7
#Echo %8
#Echo %9
shows this result, how your arguments are being parsed most likely.
C:\Users\User>"C:\Users\User\Desktop\New Text Document.bat" --args -url=chrome://crash -disable-web-security -script-url=https://172.27.68.6/pre_alpha/
--args
-url
chrome://crash
-disable-web-security
-script-url
https://172.27.68.6/pre_alpha/
Which shows a errant space after crash. And maybe you neeed to escape = with a ^, so ^=. Fix first error, then see if you need to escape the equals.

Use:
Runtime.getRuntime().exec("YOUR_COMMAND");

loop through files and execute jar with each file passed as arguments

cd /D "%~dp0"
#echo off
for %%f in ("Z:\java_projects\IDS\trunk\deployment\config\client\%1\Documentation\MappingEngine_*.xml")
do(
echo %%~nxf
java -jar EngineUtil.jar 192.67.64.172 %%f
)
Please tell me what I'm doing wrong.
I want to create a batch file to loop through a set files from a directory and run a jar file with one file at a time passed as argument.
The directory is dependent on a command line parameter.

Trying to start two .bat files with a .bat file

I'm trying to set up a Minecraft Server and actually everything works fine. I'm starting the Server with a launch.bat file.
"%ProgramFiles%\Java\jre1.8.0_20\bin\java.exe" -Xmx2G -Xms1G -jar Tekkit.jar nogui
pause
And I have a second .bat file for backup purposes.
SET COUNTER=0
:loop
SET /a COUNTER=%COUNTER%+1
XCOPY "Server\*" "c:\Users\Benjamin\Desktop\Tekkit Server\backups\server_backup_%COUNTER%" /i /s
PING 1.1.1.1 -n 1 -w 600000 > NUL
goto loop
Now, all I'm trying to do is to start the two .bat files simultaneously, using only one .bat file.
I tried it with a third .bat file to start all:
start cmd /k CALL "C:\Users\Benjamin\Desktop\Tekkit Server\Server\launch.bat"
start cmd /k CALL "C:\Users\Benjamin\Desktop\Tekkit Server\backup.bat"
pause
It will actually start both .bat files, but suddenly, they start acting up and won't find their own files again:
C:\Users\Benjamin\Desktop>"C:\Program Files\Java\jre1.8.0_20\bin\java.exe" -Xmx2G -Xms1G -jar Tekkit.jar nogui
Error: Unable to access jarfile Tekkit.jar
C:\Users\Benjamin\Desktop>pause
Drücken Sie eine beliebige Taste . . .
C:\Users\Benjamin\Desktop>SET COUNTER=0
C:\Users\Benjamin\Desktop>SET /a COUNTER=0+1
C:\Users\Benjamin\Desktop>XCOPY "Server\*" "c:\Users\Benjamin\Desktop\Tekkit
Server\backups\server_backup_1" /i /s
File * not found
0 File(s) copied
C:\Users\Benjamin\Desktop>PING 1.1.1.1 -n 1 -w 600000 1>NUL
All three .bat files are in different directories.
Does anybody have a clue what I could do about my problem (besides stop being lazy, trying to reduce 2 clicks down to one ;) )
Thanks a lot
Benny

The problem is most likely your path directory. when you do cmd, cd to the "right" directory first, then run the bat file. for example:
cmd /k "cd /my/app/path && app.bat"
the && is the separator for multiple commands

shell scripting: java program can't find property file when starting by sh

I am starting a java programm under Red Hat Enterprise Linux Server release 5 (Tikanga).
directory structure:
- bin ->sc.jar,start-sc.sh,sc-lib-all.jar
- conf->log4j-sc.properties,sc.properties
command to run the java programm (which is perfectly working):
/usr/java/jdk1.6.0_37/bin/java -Xmx1024M -Dlog4j.configuration=file:../conf/log4j sc.properties -jar sc.jar -config ../conf/sc.properties
if i put it into a shell script the java programm can't find the prop file anymore.
shell script (start-sc.sh) looks like:
#!/bin/sh
/usr/java/jdk1.6.0_37/bin/java -Xmx1024M -Dlog4j.configuration=file:../conf/log4j-sc.properties -jar sc.jar -config ../conf/sc.properties
i am a newbie on shell scripting any ideas what i am missing? thx!

i guess you started your shell script not from the bin directory, which the dir start-sc.sh belongs to.
to explain it clear, let's make an example.
say, your script is here:
/foo/bar/bin/start-sc.sh
if you start it under /foo/bar/bin/, it (the relative path) should work.
but if you start your script from /home/yourHome/someDir/ , the relative path will point to $PWD/../, which is /home/yourHome/
you could either in your script first cd /foo/bar/bin/ before you start the java app. or do something like:
a=`dirname $0`
if [ $a = '.' ];then
a=`pwd`
fi
cd $a
/usr/java/jdkxxxx/java .....

It sound fine to me, does this version work?
#!/bin/sh
/usr/java/jdk1.6.0_37/bin/java -Xmx1024M -Dlog4j.configuration=file:$(pwd)/../conf/log4j-sc.properties -jar sc.jar -config $(pwd)/../conf/sc.properties
Edit #1:
Try put the following before launching your program:
echo `pwd`
The output tells you where you are running your script, so you can check if it's the right path or not.
Edit #2:
Try this script
#!/bin/bash
LOG4JCONF="/absolute/path/to/the/log4j/conf/file"
SCCONF="/absolute/path/to/the/other/conf/file"
/usr/java/jdk1.6.0_37/bin/java -Xmx1024M -Dlog4j.configuration=file:$LOG4JCONF -jar sc.jar -config $SCCONF
