NoClassDefFoundError: org/apache/commons/lang3/StringUtils

我正在尝试 运行 使用 this 库的示例项目,但出现以下错误:

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

我添加了 commons-lang-2.6.jar & commons-lang3-3.1-sources.jarlibsclasspath

主要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);
    }
}

我参考了以下链接:

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

这是您的问题:commons-lang-2.6.jar 不包含 org.apache.commons.lang3 包,因为它是版本 3 的一部分,并且 commons-lang3-3.1-sources.jar 包含源代码,而不是字节码。

您需要包含 commons-lang3-3.1.jar

如果您正在使用 Maven,请将其放入您的 pom.xml 文件中:

Commons Lang 的 Maven 中央存储库:

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

Apache Commons Lang 的 Maven 中央存储库:

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

Don't forget: Update Maven Project

参考:

当其他一切都正确时,jar 文件很少会损坏。确保你在编译时没有看到类似下面的错误

[ERROR] error reading 
C:\Users\Mohan\.m2\repository\org\apache\commons\commons-lang3.7\commons-lang3-3.7.jar; 
ZipFile invalid LOC header (bad signature)

添加以下内容并更新 maven pronject 非常有效

<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-lang3</artifactId>
<version>3.1</version>

我在更新到 2018.3.4 并在 Maven 选项选项卡上单击 "Generate sources and update folders for all projects" 后,我在 IJ 2016 版中遇到了这个问题,问题消失了

添加以下对我有用

   <dependency>
                <groupId>org.apache.commons</groupId>
                <artifactId>commons-math3</artifactId>
                <version>3.6.1</version>
