Sounds like you need an external tool for this. If you can depend on unix tools, you can use the paste command (see man paste ) and run it from ant using the exec task. If not, you can either

• write the tool in java, then use tasks javac and java to compile and run it from ant
• or use the script task to embed the tool in your ant script using some scripting language
