使用 maven eclipse AsciidoctorJ 时出现 java.lang.NoClassDefFoundError

Question

我正在尝试使用 Asciidoctor 使用 asciidocj (convertFile) 中内置的方法生成 html 文件我收到 java.lang.NoClassDefFoundError:org/asciidoctor/OptionsBuilder

我正在研究 eclipse ； maven 和我在 pom.xml 文件中添加了 Asciidoctor 依赖项。

public void view(String document) {
        OptionsBuilder op = OptionsBuilder.options().toFile(false);

        Asciidoctor asciidoctor = create();

        String html = asciidoctor.convertFile(new File(this.path + "/" + document + ".adoc"), op.asMap());
        System.out.println(html);
    }

mvn安装，打包一切正常，当我执行该程序时，我收到此错误。我读到它是关于类路径等...但我不明白该怎么做

谢谢。

一般来说，maven 程序集插件会生成另一个名为 target/PriseDeNotes-0.0.1-SNAPSHOT-jar-with-dependency.jar 的 .jar。您可以尝试 java -jar target/PriseDeNotes-0.0.1-SNAPSHOT-jar-with-dependency.jar 来运行该应用程序。
