As you intuitively know, you don't really need to use ant to do much of
anything inside Buildr.
By changing the settings for the target and source you can take care of the
file management automatically. Cleaning, rebuilding, dependencies etc. By
setting compile with, you can add all your dependencies.
Here's an example:
To set the target and source, you define a "layout" which reassigns the
defaults, for example, to change your Java source to src/, and to use a
custom built_dir/ target directory,
my_layout = Layout.new
my_layout[:source, :main, :java] = 'src'
my_layout[:target, :main] = 'build_dir'
Then make your project use it:
define "myproject" , *:layout=>my_layout *do
to add dependencies,
define an array of libraries and paths, for example
AXIS2 = 'org.apache.axis2:axis2:jar:1.2'
LIB = ["jars/*.jar", AXIS2]
and change the compile directive to use with:
...
compile.with LIB# Added classpath dependencies
package(:jar)
end
So this will compile and jar using both an external dependency, which will
be automatically downloaded, and your local libraries. You can pretty much
run Java directly from inside Buildr too: Java.System.out.println("this
prints")
That might be an easier way fo running JAXB.
