Maven Dependency Tree Parser

WARNING: This project is not actively maintained anymore.

This library contains:

• A set of parsers that parse the output of the Maven command mvn dependency:tree; different parsers can be used to parse the following output formats: text, dot, graphml and tgf. See the Maven Dependency Plugin Tree Mojo page for further details.

To use the parser, one needs to generate a file containing the tree to parse:

mvn dependency:tree -DoutputFile=/path/to/file -DoutputType=text

Then the following idiom is the recommended way to parse the file:

InputType type = InputType.TEXT;
Reader r = new BufferedReader(new InputStreamReader(new FileInputStream(...), "UTF-8"));
Parser parser = type.newParser();
Node tree = parser.parse(r);

Note that this library does NOT make any dependency resolution whatsoever per itself; it simply takes an already-built dependency tree and parses it to an object representation that is lightweight and easily reusable.

• A set of visitors that can be used to scan the parsed tree. In particular, visitors can be used to create human-readable representations of the parsed tree. E.g. the following code transforms the parsed tree back again to the Maven standard text format:

Node tree = ...; 
StandardTextVisitor visitor = new StandardTextVisitor();
visitor.visit(tree);
System.out.println(visitor);

• A set of Velocity renderers that create HTML representations of the parsed tree. These renderers rely upon JQuery and some JQuery plugins:
  • JSTree: see http://www.jstree.com/
  • TreeTable: see http://plugins.jquery.com/project/treeTable (note: this plugin seems dead as of 2017)

These utilities are intended as examples of HTML code; feel free to adapt them to your needs. To generate the HTML code and all the secondary resources (images, CSS files, etc.), run the class fr.dutra.tools.maven.deptree.extras.VelocityRendererMain with the following arguments:

• Full path of dependency tree file to parse;
• Dependency tree file format; one of: TEXT, DOT, GRAPHML or TGF;
• Full path to the output directory where HTML files and static resources will be generated (this directory will be erased prior to file generation);
• Renderer format; one of:
  • JQUERY_JSTREE (uses JQuery plugin JSTree)
  • JQUERY_TREE_TABLE (uses JQuery plugin TreeTable)
