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:

How exactly are you running it? – Individuate

I got this error for selenium, i noticed that i added some files manually & some with maven, wich caused this error.. So probably a problem with the compatibility between selenium and htmlDriver (in my case) – Whimper

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.

which dependency is it? – Squalid

@Squalid The apache commons-lang home page has instructions to download it directly, or include it as a maven dependency. – Undercarriage

ah yes i found it i forgot to remove the comment sry – Squalid

I have <version>3.3.2</version> of commons-lang3 in pom. This did not solve the issue. I still get java.lang.NoClassDefFoundError: org/apache/commons/lang3/StringUtils. Here is the code which has this error if (StringUtils.equals(blah.getHaha().getLaugh(), "hehe")). – Shushubert

@Shushubert In the comments here isn't a great place to try to ask a question. If this answer didn't help you, it may be because you have a different problem than the OP. Try posting your own question, including your code and pom.xml. – Undercarriage

Thanks, @azurefrog. The provided solution worked for me. Cheers!! – Anallise

Answer 2

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>3.12</version>
</dependency>

Answer 5

When everything else is correct, rarely jar file gets corrupted. Ensure you don't see error something like below while compiling

[ERROR] error reading 
C:\Users\Mohan\.m2\repository\org\apache\commons\commons-lang3\3.7\commons-lang3-3.7.jar; 
ZipFile invalid LOC header (bad signature)
