Redmine

Redmine Java API supports creating subprojects: http://code.google.com/p/redmine-java-api/

Thank you, Alexey. I have checked out the project redmine-java-api, and tested it, it can create/update a project, but cannot create or update a subproject.

take a look at this test code:

/* This tests finally PASSES after Redmine bug http://www.redmine.org/issues/8229 was fixed
      */
    @Test
    public void subProjectIsCreatedWithCorrectParentId() {
        Project createdMainProject = null;
        try {
            createdMainProject = createProject();
            Project subProject = createSubProject(createdMainProject);

Assert.assertEquals("Must have correct parent ID",
                    createdMainProject.getId(), subProject.getParentId());
        } catch (Exception e) {
            Assert.fail();
        } finally {
            if (createdMainProject != null) {
                try {
                    mgr.deleteProject(createdMainProject.getIdentifier());
                } catch (Exception e) {
                    Assert.fail();
                }
            }
        }
    }

private Project createProject() throws IOException, AuthenticationException, RedmineException, NotFoundException {
        Project mainProject = new Project();
        long id = new Date().getTime();
        mainProject.setName("project" + id);
        mainProject.setIdentifier("project" + id);
        return mgr.createProject(mainProject);
    }

private Project createSubProject(Project parent) throws IOException, AuthenticationException, RedmineException, NotFoundException {
        Project project = new Project();
        long id = new Date().getTime();
        project.setName("sub_pr" + id);
        project.setIdentifier("subpr" + id);
        project.setParentId(parent.getId());
        return mgr.createProject(project);
    }

Thank you very much, Alexey. That is OK!
