java - How to get MavenProject in maven3 -

-

i want automate part of our build system in java. need calculate dependency tree of sources existent in given file tree.

so, want crawl on set of directories , find pom.xml files existent there. works fine. want parse files instances of mavenproject can call getparent() , getdependencies() , such on it.

so, question is: how populated mavenproject maven3 libraries? acceptable me include third party library if necessary prefer solution consists of maven natives.

i have read get mavenproject pom.xml - pom parser? answers there don't work me (the mavenproject not not populated correctly)

my code in java, want have contents of method this:

private mavenproject makeprojectfrompom(file pomxml) {     // here don't know. }

so can in program:

public list<mavenproject> getallmavenprojectswithparent(file rootdir, mavenproject parent) {    list<file> allpoms = findallpoms(rootdir);    list<mavenproject> result = new arraylist<>();    for(file nextpom : allpoms) {        mavenproject next = makeprojectfrompom(nextpom);        if(next.hasparent() && next.getparent().equals(parent))            result.add(next);    }    return result; }

this example, 1 not work @ moment me.

in maven2 this:

    string basepath = "somepath";     mavenembedder embedder = new mavenembedder();     file basedir = new file(basepath);     final list<file> alldirswithpomxml = new arraylist<>();     // next line crawls through directory , collects references pom.xml paths.     gatherpomxmlpaths(basedir, alldirswithpomxml);     embedder.setclassloader(this.getclass().getclassloader());     embedder.start();     list<mavenproject> collectedprojects = new arraylist<>();     (file nextdir : alldirswithpomxml) {         collectedprojects.addall(embedder.collectprojects(nextdir, new string[]{"pom.xml"}, new string[0]));     }

the mavenproject references in collectedprojects contain information parent, dependencies etc.

java - UML - How would you draw a try catch in a sequence diagram? -

Image
is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
