问题:

I have to look into some complicated Ant files which include targets of other Ant files and these others, targets from the original etc.
Is there a (visual) tool that helps understand Ant files and structure and how they end up building the deliverables?

回答1:

You can try this tools:

ant2dot - using GraphViz toolkit to generate the final graph;
Vizant - using GraphViz toolkit to generate the final graph;
Grand - using GraphViz toolkit to generate the final graph;
ant-script-visualizer - using GraphViz toolkit to generate the final graph.

The IntelliJ IDEA has a very good support (has native plugin and several 3rd party plugins) of Apache Ant. You can read about Ant support in IDEA here.

At my work we've had good results with Grand.

Here is another link to various Ant visualization tools.

But there is a plugin for IntelliJ IDEA available and you will
still find some sources for the standalone version, f.e. here
