Question

The company I work for uses Mac computers exclusively. While I like my Mac, it is only a 13″ laptop so I decided to setup my environment on my Windows pc as I have two 24″ monitors to work from. I want to be able to use devMode so I can update the UI without having to recompile everything. I was wondering if there is an easy way to convert a bash shell script into a windows batch file. Im not experienced at all in creating batch files so any help would be greatly appreciated

edit: I used Cygwin and I get the error:

$ ./devMode_osx.sh
Listening for transport dt_socket at address: 5006
Error: Could not find or load main class com.google.gwt.dev.DevMode

Here’s the file

#!/bin/sh
#
# Startup script for hosted mode.
# You have to add MAVEN_REPO to your variables; for example:
#
# export MAVEN_REPO="/Users/james/.m2/repository"

Answer 1

Two approaches:

1. Use Cygwin (www.cygwin.com) to run a Bash shell script under Windows.

2. Take a basic batch programming tutorial.

   Pay attention to the part of setting and accessing variables.

   And then try to modify your bash script

   Hint 1 setting variables

   instead of

   MAVEN_REPO="C:/Users/James/.m2/repository"
   

   use

   SET MAVEN_REPO="C:/Users/James/.m2/repository"
   

   ---

   Hint 2 using variables

   instead of

   BASE_JAVA_SRC="$APPDIR/../src/main/java"
   

   use

   SET BASE_JAVA_SRC="%APPDIR%/../src/main/java"
   

   ---

   Hint 3 review use of external commands and SO idiosyncrasies

   instead of

   APPDIR=`dirname $0`;
   

   use

   SET APPDIR=%~dp0
