Fix Eclipse log4j WARN

Eclipse complains log4j settings

log4j:WARN No appenders could be found for logger (com.spotify.docker.client.DockerConfigReader).
log4j:WARN Please initialize the log4j system properly.

Solution

create a file log4j.properties according to this post

# Root logger option
log4j.rootLogger=INFO, file, stdout

# Direct log messages to a log file
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=/Users/ozhang/oss/log4j/eclipse/eclipse.log
log4j.appender.file.MaxFileSize=10MB
log4j.appender.file.MaxBackupIndex=10
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
 
# Direct log messages to stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

Add a line to /Applications/Eclipse.app/Contents/Eclipse/eclipse.ini

-Dlog4j.configuration=file:///Users/ozhang/oss/log4j/log4j.properties

Result: 

Eclipse does not complain log4j any more.
