Any shell task that uses output or error streams extensively (e.g. CPP) take inordinately long in Ant compared to running it from the command line (a difference from 30 seconds to 10+ minutes). This is due to the fact that org.apache.tools.ant.taskdefs.StreamPumper sleeps for 5ms after it reads 128 bytes. Because the executing thread will block until the existing output is cleared and the StreamPumper would block when there is no more input, there should be no reason to sleep.
The only solution I found is to use my own task definition and use my own PumpStreamHandler with its own StreamPumper. Could we get this fixed for all exec tasks? The simplest approach is to just remove the Thread.sleep(...) call.
