7 """An Ant wrapper that suppresses useless Ant output. | |
8 | |
9 Ant build scripts output "BUILD SUCCESSFUL" and build timing at the end of | |
10 every build. In the Android build, this just adds a lot of useless noise to the | |
11 build output. This script forwards its arguments to ant, and prints Ant's | |
12 output up until the BUILD SUCCESSFUL line. | |
13 | |
14 Also, when a command fails, this script will re-run that ant command with the | |
15 '-verbose' argument so that the failure is easier to debug. | |
