1. Put the following log4j.properties file at root directory at the Eclipse JUnit project

####################################
# Categories & Levels
####################################
#For develop
log4j.rootCategory=DEBUG, ConApp, FileApp 

####################################
# Appender
####################################

# ConApp is set to be a ConsoleAppender
log4j.appender.ConApp=org.apache.log4j.ConsoleAppender
log4j.appender.ConApp.layout=org.apache.log4j.PatternLayout
log4j.appender.ConApp.layout.ConversionPattern=%d [%t] %-5p %l - %m%n

# FileApp is to create log-file using FileAppender
log4j.appender.FileApp=org.apache.log4j.FileAppender
log4j.appender.FileApp.File=./test.log
log4j.appender.FileApp.ImmediateFlush=true
log4j.appender.FileApp.Append=false
log4j.appender.FileApp.layout=org.apache.log4j.PatternLayout
log4j.appender.FileApp.layout.ConversionPattern=%d [%t] %-5p %l - %m%n

2. Add static initializer to JUnit test class

private static Logger gLogger = Logger.getLogger(TestClass.class);

static 
{
	PropertyConfigurator.configure("log4j.properties");
}

Run a JUnit test, then log4j log will be shown at console and file.

cat plugin_directory/plugin.properties

aboutText=blah blah\n\n\
Build Number: 

cat build.xml

...

<target name="before-pde-build">

<echo file="${buildDirectory}/plugins/plug_in_name/plugin.properties" message=${env.BUILD_NUMBER}" append="true"/>
</target>
