Hi, I have what I think is a simple need but I unfortunately cannot figure out the correct way to setup the build file to accomplish my goal. Essentially, I want to use the Replace feature of Ant to replace the tokens in a file in a template directory as it the target file. The problem is that there is not a 1:1 mapping between the source file and the target files, but rather a 2:1 mapping. For example, I have a directory structure like: T01_Audit_I01.properties T02_Audit_I01.properties T03_Audit_I01.properties templates/Audit_I01.template Basically, I want Ant to convert each of the ".properties" files into a ".sql" file by using the templates/Audit_I01.template file as a template and replacing tokens based on the content of the respective ".properties" file. So, after processing the directory should look like: T01_Audit_I01.properties T01_Audit_I01.sql T02_Audit_I01.properties T02_Audit_I01.sql T03_Audit_I01.properties T03_Audit_I01.sql templates/Audit_I01.template But I can't seem to figure out how to tell Ant to do this. It seems like the Replace command is the way to go, but I am unclear on how to convey this 2:1 sourcefile/targetfile mapping to Ant. In particular, I don't want to have to modified build.xml every time that I add a new pair of template/properties; rather, I want Ant to operate at the directory level by scanning the directory structure and then taking the appropriate actions. Perhaps one way is to specified the source template filename as a property in the properties file itself? That would work great, but I am unclear as to how to tell Ant to do that. Any and all help most appreciate! This seems to me like a simple task, but I am having quite some difficulty in figuring out how to get Ant to do this. Thanks! Doug
