System.out with Ant

Question

I'm googling without success to figure out how to make ANT print System.out.println/System.out.print messages in the console. Messages simply don't appear. I haven't found any simple way of doing this. Is there any?

Thanks

Answer 1

The junit task printsummary attribute has a special setting withOutAndErr that:

is the same as on but also includes the output of the test as written to System.out and System.err.

Answer 2

Use the echo task

<echo message="Hello, world"/>
<echo message="Hello, file" file="logfile.txt" />

If you want to read the output from a <java> task, use the outputproperty attribute:

<java ... outputproperty="javaoutput" />
<echo message="${javaoutput}" />
