英文:

NoClassDefFoundError occurs when using the swagger2Markup

问题

**swagger2Markup maven**
```xml
<dependency>
    <groupId>io.github.swagger2markup</groupId>
    <artifactId>swagger2markup</artifactId>
    <version>1.3.1</version>
</dependency>

测试方法
当我运行这个方法时，出现了错误

    @Test
    public void generateAsciiDocs() throws Exception {
        // 输出Ascii格式
        Swagger2MarkupConfig config = new Swagger2MarkupConfigBuilder()
                .withMarkupLanguage(MarkupLanguage.ASCIIDOC)
                .withOutputLanguage(Language.ZH)
                .withPathsGroupedBy(GroupBy.TAGS)
                .withGeneratedExamples()
                .withoutInlineSchema()
                .build();

        Swagger2MarkupConverter.from(new URL("http://localhost:8088/v2/api-docs?group=api"))
                .withConfig(config)
                .build()
                .toFolder(Paths.get("src/docs/asciidoc/generated/all"));
    }

稍后运行

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/beanutils/BeanIntrospector

什么是 NoClassDefFoundError？

**test method**
When I run this method, it goes wrong

@Test
public void generateAsciiDocs() throws Exception {
    //    输出Ascii格式
    Swagger2MarkupConfig config = new Swagger2MarkupConfigBuilder()
            .withMarkupLanguage(MarkupLanguage.ASCIIDOC)
            .withOutputLanguage(Language.ZH)
            .withPathsGroupedBy(GroupBy.TAGS)
            .withGeneratedExamples()
            .withoutInlineSchema()
            .build();

    Swagger2MarkupConverter.from(new URL("http://localhost:8088/v2/api-docs?group=api"))
            .withConfig(config)
            .build()
            .toFolder(Paths.get("src/docs/asciidoc/generated/all"));
}

**run later**

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/beanutils/BeanIntrospector

# what the NoClassDefFoundError ???
