How to execute ant scripts in a differing directory to a shell script? I'm writing a shell script to automate an elaborate build process. It includes execution of multiple `ant` scripts located in different directories. The shell script is in my home directory, while the ant scripts are located in: `/opt/myApp/module1/ ant -f patch.xml`, and `/opt/myApp2/module2 ant build.xml`. How can I invoke ant command in my shell script, from a different folder location?

You can create a module in master ant file which contains corresponding ant files. For eg:

You can make a master file as

> /opt/Makefile


all:
(make module1)
(make module2)

module1:
(cd myApp/module1/; ant -f patch.xml)

module2:
(cd myApp2/module2; ant -buildfile build.xml)


Then you can run the master Makefile as:

> `$ make Makefile all`
