NoClassDefFoundError: org/apache/commons/lang3/StringUtils

Question

I'm trying to run the sample project with this library and I get the following error:

Exception in thread "main" java.lang.NoClassDefFoundError: 

    org/apache/commons/lang3/StringUtils

I've added commons-lang-2.6.jar & commons-lang3-3.1-sources.jar in libs and classpath

Main class:

public static void main(final String[] args) throws CardException {
    Main pcsc = new Main();
    CardTerminal ct = pcsc.selectCardTerminal();
    Card c = null;
    if (ct != null) {
        c = pcsc.establishConnection(ct);
        CardChannel channel = c.getBasicChannel();
        PcscProvider provider = new PcscProvider(channel);
        EmvParser parser = new EmvParser(provider, false);
        parser.readEmvCard();
        c.disconnect(false);
    }
}

I have referred to the following links:

Answer 1

I have added commons-lang-2.6.jar & commons-lang3-3.1-sources.jar...

Here's your problem: commons-lang-2.6.jar doesn't contain the org.apache.commons.lang3 package, since that's part of version 3, and commons-lang3-3.1-sources.jar contains the source code, not the byte code.

You need to include commons-lang3-3.1.jar instead.

If you're using Maven, put this inside your pom.xml file:

Maven Central Repository for Commons Lang:

<dependency>     <groupId>commons-lang</groupId>     <artifactId>commons-lang</artifactId>     <version>2.6</version> </dependency> 

Maven Central Repository for Apache Commons Lang:

<dependency>     <groupId>org.apache.commons</groupId>     <artifactId>commons-lang3</artifactId>     <version>3.11</version> </dependency>

Don't forget: Update Maven Project
