I don't know if there's a way to do it in buildr alone, but here's my version
of "my_transitive":
# Adds some methods for cleaner dependency on another project and its deps
class Buildr::Project
def and_dependencies
[self, self.compile.dependencies].compact
end
def test_dependencies
[self.test.compile.target, self.test.resources.target,
self.test.compile.dependencies].compact
end
end
Use it like this:
define 'myProject' do
define 'A' do
compile.with DEP_A_1, DEP_A_2, DEP_A_3
package :jar
end
define 'B' do
compile.with project('A').and_dependencies, DEP_B_1, DEP_B_2
package :war
end
end
