Using zxing on Windows7 and JAVA 64bit

Question

can anyone guide me on how I can use zxing for a little java tool I'd like to write.

I was starting here: https://github.com/zxing/zxing/wiki/Getting-Started-Developing

Then I moved to: http://repo1.maven.org/maven2/com/google/zxing/

The problem is I do not know which package to download!

What are these folders for?

android-core/                                      15-Feb-2015 13:05                   
android-integration/                               15-Feb-2015 13:05                   
core/                                              15-Feb-2015 13:05                   
glass-mirror/                                      02-Dec-2013 11:10                   
javase/                                            15-Feb-2015 13:05                            
zxing-parent/                                      15-Feb-2015 13:05                   
zxing.appspot.com/                                 15-Feb-2015 13:05                         
zxingorg/                                          15-Feb-2015 13:05

I guessed and tried the folder zxingorg/3.2.0/

But there are two jar files.

 zxingorg-3.2.0-javadoc.jar
 zxingorg-3.2.0-sources.jar

Which one is the right one?

I tried zxingorg-3.2.0-javadoc.jar. I put this file in the same folder that also contains my qrtest.java file.

I opened a command window moved to that folder and wrote:

javac -cp zxingorg-3.2.0-javadoc.jar qrtest.java

Unfortunately I get:

qrtest.java:11: error: package com.google.zxing does not exist
import com.google.zxing.BarcodeFormat;

So, where is the mistake I made?

Many thanks in advance

If you're developing a Java desktop application you only need core and javase modules.

zxingorg is a web application. The app behind http://zxing.org.

If you use Maven, include the following in your pom.xml:

    <dependency>
        <groupId>com.google.zxing</groupId>
        <artifactId>core</artifactId>
        <version>${com.google.zxing.version}</version>
    </dependency>

    <dependency>
        <groupId>com.google.zxing</groupId>
        <artifactId>javase</artifactId>
        <version>${com.google.zxing.version}</version>
    </dependency>

Were com.google.zxing.version is the desired zxing version. I recommend 3.2.0.

If not using maven, just download the jars and add them as dependencies.

core core-javadoc javase javase-javadoc

After that you're going to be able to proceed with your first steps with the library.

For further reference you can also download the sources.

core-src javase-src

An example of what you're going to be able to do is CommandLineRunner.java (which is part of javase module)
