J2OBJC_HOME not correctly defined in LibConfig.xcconfig

Question

I was trying to run a J2OBJC sample from this "https://github.com/yixiang/Xcode-J2ObjC-Example" repository. I am facing some issue while building this project.

the error is listing below.

VERSION_INFO_STRING="\"@(#)PROGRAM:SharedCode  PROJECT:J2ObjCExample-\""

J2OBJC_HOME not correctly defined in LibConfig.xcconfig, currently set to '/Users/******/bin/j2objc'
Command /bin/sh failed with exit code 1

But I can able to echo the $J2OBJC_HOME and getting path too. *****-MacBook-Pro:j2objc-2.0.5 ******$ echo $J2OBJC_HOME /Users/******/bin please help me to resolve this issue. thanks in advance.

Attaching the config files with this question

As the sample app's README states (https://github.com/yixiang/Xcode-J2ObjC-Example/blob/master/README.md#prerequisite), you need to set the J2OBJC_HOME variable in two places: J2ObjCExample/AppConfig.xcconfig and SharedCode/LibConfig.xcconfig. — tball, Nov 21 '17 at 16:12
@tball I am already set the J2OBJC_HOME variable in two places: J2ObjCExample/AppConfig.xcconfig and SharedCode/LibConfig.xcconfig. Is there any J2OBJC version issue? — Joseph, Nov 22 '17 at 04:14
@tball I have updated the question with latest error and screenshot. — Joseph, Nov 22 '17 at 04:38

Here are the steps I took:

Cloned sample project: $ cd ~/src $ git clone https://github.com/yixiang/Xcode-J2ObjC-Example.git $ cd Xcode-J2ObjC-Example
Downloaded j2objc 2.0.5 to ~/Downloads, then clicked to expand it.
Ran open J2ObjCExample/J2ObjCExample.xcodeproj/ to open project in Xcode, version 9.1.
Edited AppConfig.xcconfig and LibConfig.xcconfig, editing the J2OBJC_HOME line in each to read J2OBJC_HOME = ${HOME}/Downloads/j2objc-2.0.5;.
Build, it fails with: j2objc: invalid flag: --no-class-methods Usage: j2objc <options> <source files> use --help for a list of possible options
Selected SharedCode target, then Build Rules, removed --no-class-methods flag.
Translation and compilation succeeds, link fails with missing iconv* symbols.
Selected J2ObjCExample target, Build Phases, Link Binary With Libraries. Clicked +, typed iconv, clicked libiconv.tbd, clicked Add.
Build succeeds and app runs.

I don't know why your current workspace is failing, but recommend you delete it and follow the above steps.
