It would be a great advantage of Bamboo to be able to retrieve an artifact from a project build (specifically JAR files), to be included in the classpath of other dependent projects. Many development shops maintain a "common" library of code that is reused between different projects and even development teams. This concept is not supported in most CI environments. What I would recommend would be a way to import dependencies from artifacts. These dependencies may or may not trigger a build of the parent project to produce the artifacts, depending on the configuration. These artifacts could simply be referenced in the Ant script with the -lib option.
