I am using Maven 3.1.1 and exec-maven-plugin(1.3) to execute a bash script during a build job.
The bash script prints the output to stdoutc echoand printf. I noticed that the script output is not written to the maven console output instantly. Instead, the maven console output freezes until it is updated with several bash script output lines at once. I don’t know which trigger to update maven output (timeout? Full output buffer?), But it is very slow.
Take a very simple bash script, for example. counter.sh:
#!/usr/bin/env bash
for i in `seq 1 1000`; do
echo $i
sleep 0.5
done
And here is my plugin configuration in pom.xml:
