How do I get java logging output to appear on a single line?

by

As of Java 7, java.util.logging.SimpleFormatter supports getting its format from a system property, so adding something like this to the JVM command line will cause it to print on one line:

-Djava.util.logging.SimpleFormatter.format="%1$tY-%1$tm-%1$td %1$tH:%1$tM:%1$tS %4$s %2$s %5$s%6$s%n"

Alternatively, you can also add this to your logger.properties:

java.util.logging.SimpleFormatter.format="%1$tY-%1$tm-%1$td %1$tH:%1$tM:%1$tS %4$s %2$s %5$s%6$s%n"
