One of the essential approaches to simplifying the build process is using
convention over configuration, so if you use the Buildr conventions, you get
rewarded by not having much code at all to do the needful.
If you try to do something really oddball you will--if you can get it to work
at all--end up with a much more complicated buildfile than necessary. The
basic idea is that subprojects are part of a hierarchy, have their files in
certain places etc.
If you do have an existing project that you want to support (typical case is a
Java project with source in "src") you can tweak Buildr to work for you. For
example, you can use child layouts to swap to a non-standard source or even
target.
Here's a snippet of three child tasks, where child3 subproject has NOT been
converted to the standard src/main/java convention:
..
child_layout = Layout.new #<=============
child_layout[:source, :main, :java] = 'src' #<=============
child_layout[:target, :main] = 'build_dir' #<=============
define "child1" do
compile.with # Add classpath dependencies
package(:jar)
end
define "child2" do
compile.with # Add classpath dependencies
package(:jar)
end
define "child3", :layout=>child_layout do #<=============
compile.with # Add classpath dependencies
package(:jar)
end
...
