Maven - Bin (Bash and Bat file creation)

Properties definition

# The property to create a bat and sh file
# main.FileName is the name of the bat and sh file
# main.Class is the name of the main class. It will be replaced in the template
Main.FileName=fileName
Main.Class=mypackage.MyMainClass

Template

• the bash template

#!/usr/bin/env bash

SCRIPT_PATH=$( cd $(dirname $0) ; pwd -P )

# The cypath transformation is needed if we are on Windows
if [ -e "/usr/bin/cygpath" ]
then
  LIB_PATH="$(cygpath -w $SCRIPT_PATH/lib/)*"
else
  LIB_PATH="$SCRIPT_PATH/lib/*"
fi

# ${1+"$@"} is mandatory if we want to preserve the quotation of the arguments
# otherwise every space will split an argument in two
# See https://stackoverflow.com/questions/743454/space-in-java-command-line-arguments
$SCRIPT_PATH/jre/bin/java -classpath "$LIB_PATH" ${Main.Class} ${1+"$@"}

• the bat template

@echo off

@REM The script path to reference the included JRE java file
SET SCRIPT_PATH=%~dp0

:APPEND_CLASSPATH
SET CLASSPATH="%SCRIPT_PATH%\lib\*"

%SCRIPT_PATH%\jre\bin\java -classpath %CLASSPATH% ${Main.Class} %*

copy-resources Plugin definition

In the Pom.xml, we add a copy-resources goal with the following option:

• fileNameFiltering is true: to be able to have another file for each main class.
• filter containing the path of the property file
• filtering is true, to replace the property in the the bash and bat template files.
• resource > directory containing the path of the bash and bat template files.
