java - Maven Plugin: accessing resources accross multiple modules -

i'm writing custom maven plugin generating xml file in multi-module maven project.

my maven structure pretty standard: 1 parent project , module project components in parent project folder:

-- parent   -- module   -- module b   -- module c 

i need list, module, set of classes flagged custom annotation. wrote set of custom annotations , annocation processor create xml file @ compile time in corresponding module output directory (${project.build.outputdirectory}) .

now need merge each module xml 1 file, don't know how access each modules within maven plugin except having each path set parameters (i don't method).

any idea on how ? maven plugins can traverse project modules ?

thank in advance.

to list list of projects can use:

list<mavenproject> projectlist = mavensession.getprojectdependencygraph().getsortedprojects() 

if 1 of goals correctly executed need. every mavenproject contains getbasedir() etc.
