How to call a build.xml

Hi

How to to call or execute a build.xml (ant file) from a simple java program.

java.lang.Runtime

You use the Ant.class from the Ant API and load your build.xml using the setAntFile(String fileName) and then use .execute();

This is not working...

Is the file in the appropriate place? From the Ant docs:
public void setAntfile(java.lang.String s)

The build file to use. Defaults to "build.xml". This file is expected to be a filename relative to the dir attribute given.

You can use the following method to set the directory:

public void setDir(java.io.File d)

The directory to use as a base directory for the new Ant project. Defaults to the current project's basedir, unless inheritall has been set to false, in which case it doesn't have a default value. This will override the basedir setting of the called project.

Hey... I pointed you in the right direction... not giving you the whole answer...

Yes, you have to set the running directory with obj.setDir("dir-path");

Not a beginner's topic. Moving thread.
