Question

在尝试将自定义ParserPlugin实现到我正在编写的库时，我遇到了pegdown v1.4.2的问题（Maven项目，JDK 8）：

CustomPlugin：

public class CustomHeadersParserPlugin extends Parser implements BlockPluginParser {

public CustomHeadersParserPlugin() {super(HtmlMdProc.MDP_SETTINGS, HtmlMdProc.PROCESSING_TIME_LIMIT, DefaultParseRunnerProvider);
}

public CustomHeadersParserPlugin(Integer options, Long maxParsingTimeInMillis) {
  super(options, maxParsingTimeInMillis, DefaultParseRunnerProvider);
}

public CustomHeadersParserPlugin(Integer options, Long maxParsingTimeInMillis, ParseRunnerProvider parseRunnerProvider) {
  super(options, maxParsingTimeInMillis, parseRunnerProvider);
}

public CustomHeadersParserPlugin(Integer options, Long maxParsingTimeInMillis, ParseRunnerProvider parseRunnerProvider, PegDownPlugins plugins) {
  super(options, maxParsingTimeInMillis, parseRunnerProvider, plugins);
}

//************* CUSTOM RULES ***************
...

Pegdown用法：

public class HtmlMdProc {

public static final int MDP_SETTINGS = Extensions.HARDWRAPS | Extensions.AUTOLINKS | Extensions.TABLES | Extensions.FENCED_CODE_BLOCKS;
public static final long PROCESSING_TIME_LIMIT = 5000l;
...
public HtmlMdProc markdown() {
  PegDownPlugins pdp = PegDownPlugins.builder().withPlugin(CustomHeadersParserPlugin.class).build();
  PegDownProcessor mdp = new PegDownProcessor(MDP_SETTINGS, PROCESSING_TIME_LIMIT, pdp);
  RootNode rn = mdp.parseMarkdown(text.toCharArray());
  String result = new CustomMarkdownToHtmlSerializer().toHtml(rn);
    if (result != null)
      this.text = result;
    else
      logger.debug("Could not process markdown in {} seconds", PROCESSING_TIME_LIMIT / 1000);
  return this;
}

测试：

@Test
public void testmarkdownWithoutCode() {
  String before = "Simple new line\nTest\n\nTest\nVot";
  String expected = "<p>Simple new line<br />Test</p><p>Test<br />Vot</p>".replaceAll("\r", "");
  HtmlMdProc textProc = new HtmlMdProc(before);
  String result = textProc.markdown().text();
  assertEquals(expected, result);
}

测试执行：

java.lang.RuntimeException: Error creating extended parser class: null

我可以以某种方式绑定我的CustomHeadersParserPlugin，避免幽灵般的反思吗？
如果没有，请告诉我如何在pom.xml中设置maven-bundle-plugin以使其与pegdown v 1.4.2一起使用。

我在讨论Here时发现了问题，但我太新手不能单独处理Maven插件和思考。

唯一的解决方案是等待This Issue关闭，直到我认为Pegdown和Java 8没有运气。
