Answer 2

Ant has two related features to allow the build process to be monitored => listeners and loggers :

• Ant >= 1.8.x ships with the ProfileLogger
• Ant statistics, a logger that logs executions times for all targets, and graphs them over the time
• Performance Monitor from antcontrib, a listener that keeps track of the amount of time that each target and task takes to execute and prints a final summary
