尝试从pom.xml中提取版本时发生异常

Question

我试图读取我的pom.xml以获取版本号，但始终收到以下错误：

Exception in thread "main" java.lang.NoClassDefFoundError: org/codehaus/plexus/util/xml/pull/XmlPullParserException
        at com.wenzey.core.utils.Log.sendStartupMessage(Log.java:5)
        at com.wenzey.core.Main.main(Main.java:12)
Caused by: java.lang.ClassNotFoundException: org.codehaus.plexus.util.xml.pull.XmlPullParserException
        at java.net.URLClassLoader.findClass(URLClassLoader.java:381)
        at java.lang.ClassLoader.loadClass(ClassLoader.java:424)

        at java.lang.ClassLoader.loadClass(ClassLoader.java:357)
        ... 2 more

我发现这很奇怪，因为我检查了我的罐子，并且pom.xml确实存在：

我的代码如下，它在开发人员模式下可以正常工作，但在构建程序包后无法正常工作：

VersionProvider类

class VersionProvider {
    static String getVersion() throws IOException, XmlPullParserException {
        MavenXpp3Reader reader = new MavenXpp3Reader();
        Model model;
        String VERSION_NUMBER;
        if ((new File("pom.xml")).exists()) {
            model = reader.read(new FileReader("pom.xml"));
            VERSION_NUMBER = model.getVersion();
        } else {
            model = reader.read(
                    new InputStreamReader(
                            VersionProvider.class.getResourceAsStream(
                                    "/META-INF/maven/com.wenzey/wenzey-core/pom.xml"
                            )
                    )
            );
            VERSION_NUMBER = model.getVersion();
        }
        return VERSION_NUMBER;
    }
}

主班

public class Main {

    public static void main(String[] args) throws IOException, XmlPullParserException {
        Log.sendStartupMessage();
    }
}

日志类别

public class Log {
    public static void sendStartupMessage() throws IOException, XmlPullParserException {
        String versionNumber = VersionProvider.getVersion();
        System.out.print(":: wenzey ((v." + versionNumber + ")) ::");
    }
}
