sonar-checkstyle plugin 與 sonar-findbugs plugin 差不多，代碼目錄也幾乎很相近。

sonar 插件需要擴展sensor,Exporter,Plugin,Importer類：

CheckstyleSensor 類：

import java.io.File; import java.util.Iterator; import java.util.List; import org.sonar.api.batch.Sensor; import org.sonar.api.batch.SensorContext; import org.sonar.api.batch.fs.FilePredicates; import org.sonar.api.batch.fs.FileSystem; import org.sonar.api.batch.fs.InputFile.Type; import org.sonar.api.profiles.RulesProfile; import org.sonar.api.resources.Project;public class CheckstyleSensorimplements Sensor {private final RulesProfile profile;private final CheckstyleExecutor executor;private final FileSystem fileSystem;public CheckstyleSensor(RulesProfile profile, CheckstyleExecutor executor, FileSystem fileSystem){this.profile = profile;this.executor = executor;this.fileSystem = fileSystem;}public boolean shouldExecuteOnProject(Project project){FilePredicates predicates = this.fileSystem.predicates();Iterable<File> mainFiles = this.fileSystem.files(predicates.and(predicates.hasLanguage("java"), predicates.hasType(InputFile.Type.MAIN)));boolean mainFilesIsEmpty = !mainFiles.iterator().hasNext();if (!mainFilesIsEmpty) {}return !this.profile.getActiveRulesByRepository("checkstyle").isEmpty();}public void analyse(Project project, SensorContext context){this.executor.execute();}public String toString(){return getClass().getSimpleName();}

CheckstylePlugin 繼承sonarPlugin類：

public final class CheckstylePluginextends SonarPlugin {private static final String CHECKSTYLE_SUB_CATEGORY_NAME = "Checkstyle";public List getExtensions(){return Arrays.asList(new Object[] {PropertyDefinition.builder("sonar.checkstyle.filters").defaultValue("<module name=\"SuppressionCommentFilter\" /><module name=\"SuppressWarningsFilter\" />").category("java").subCategory("Checkstyle").name("Filters").description("Checkstyle supports four error filtering mechanisms: <code>SuppressionCommentFilter</code>, <code>SuppressWithNearbyCommentFilter</code>, <code>SuppressionFilter</code>, and <code>SuppressWarningsFilter</code>.This property allows the configuration of those filters with a native XML format. See the <a href='http://checkstyle.sourceforge.net/config.html'>Checkstyle</a> configuration for more information.").type(PropertyType.TEXT).onQualifiers("TRK", new String[] { "BRC" }).build(), PropertyDefinition.builder("sonar.checkstyle.generateXml").defaultValue("false").category("java").subCategory("Checkstyle").name("Generate XML Report").type(PropertyType.BOOLEAN).hidden().build(), CheckstyleSensor.class, CheckstyleConfiguration.class, CheckstyleExecutor.class, CheckstyleAuditListener.class, CheckstyleProfileExporter.class, CheckstyleProfileImporter.class, CheckstyleRulesDefinition.class });} }

CheckstyleProfileExporter 繼承ProfileExporter

public class CheckstyleProfileExporterextends ProfileExporter {public static final String DOCTYPE_DECLARATION = "<!DOCTYPE module PUBLIC \"-//Puppy Crawl//DTD Check Configuration 1.2//EN\" \"http://www.puppycrawl.com/dtds/configuration_1_2.dtd\">";private static final String CLOSE_MODULE = "</module>";private final Settings settings;public CheckstyleProfileExporter(Settings settings){super("checkstyle", "Checkstyle");this.settings = settings;setSupportedLanguages(new String[] { "java" });setMimeType("application/xml");}public void exportProfile(RulesProfile profile, Writer writer){try{List<ActiveRule> activeRules = profile.getActiveRulesByRepository("checkstyle");if (activeRules != null){Map<String, List<ActiveRule>> activeRulesByConfigKey = arrangeByConfigKey(activeRules);generateXml(writer, activeRulesByConfigKey);}}catch (IOException ex){throw new IllegalStateException("Fail to export the profile " + profile, ex);}}private void generateXml(Writer writer, Map<String, List<ActiveRule>> activeRulesByConfigKey)throws IOException{appendXmlHeader(writer);appendCustomFilters(writer);appendCheckerModules(writer, activeRulesByConfigKey);appendTreeWalker(writer, activeRulesByConfigKey);appendXmlFooter(writer);}private static void appendXmlHeader(Writer writer)throws IOException{writer.append("<?xml version=\"1.0\" encoding=\"UTF-8\"?><!DOCTYPE module PUBLIC \"-//Puppy Crawl//DTD Check Configuration 1.2//EN\" \"http://www.puppycrawl.com/dtds/configuration_1_2.dtd\"><!-- Generated by Sonar --><module name=\"Checker\">");}private void appendCustomFilters(Writer writer)throws IOException{String filtersXml = this.settings.getString("sonar.checkstyle.filters");if (StringUtils.isNotBlank(filtersXml)) {writer.append(filtersXml);}}private static void appendCheckerModules(Writer writer, Map<String, List<ActiveRule>> activeRulesByConfigKey)throws IOException{for (Map.Entry<String, List<ActiveRule>> entry : activeRulesByConfigKey.entrySet()){String configKey = (String)entry.getKey();if (!isInTreeWalker(configKey)){List<ActiveRule> activeRules = (List)entry.getValue();for (ActiveRule activeRule : activeRules) {appendModule(writer, activeRule);}}}}private void appendTreeWalker(Writer writer, Map<String, List<ActiveRule>> activeRulesByConfigKey)throws IOException{writer.append("<module name=\"TreeWalker\">");writer.append("<module name=\"FileContentsHolder\"/> ");if (isSuppressWarningsEnabled()) {writer.append("<module name=\"SuppressWarningsHolder\"/> ");}List<String> ruleSet = new ArrayList(activeRulesByConfigKey.keySet());Collections.sort(ruleSet);for (String configKey : ruleSet) {if (isInTreeWalker(configKey)){List<ActiveRule> activeRules = (List)activeRulesByConfigKey.get(configKey);for (ActiveRule activeRule : activeRules) {appendModule(writer, activeRule);}}}writer.append("</module>");}private boolean isSuppressWarningsEnabled(){String filtersXml = this.settings.getString("sonar.checkstyle.filters");boolean result = false;if (filtersXml != null) {result = filtersXml.contains("<module name=\"SuppressWarningsFilter\" />");}return result;}private static void appendXmlFooter(Writer writer)throws IOException{writer.append("</module>");}@VisibleForTestingstatic boolean isInTreeWalker(String configKey){return StringUtils.startsWithIgnoreCase(configKey, "Checker/TreeWalker/");}private static Map<String, List<ActiveRule>> arrangeByConfigKey(List<ActiveRule> activeRules){Map<String, List<ActiveRule>> result = new HashMap();for (ActiveRule activeRule : activeRules){String key = activeRule.getConfigKey();if (result.containsKey(key)){List<ActiveRule> rules = (List)result.get(key);rules.add(activeRule);}else{List<ActiveRule> rules = new ArrayList();rules.add(activeRule);result.put(key, rules);}}return result;}private static void appendModule(Writer writer, ActiveRule activeRule)throws IOException{String moduleName = StringUtils.substringAfterLast(activeRule.getConfigKey(), "/");writer.append("<module name=\"");StringEscapeUtils.escapeXml(writer, moduleName);writer.append("\">");if (activeRule.getRule().getTemplate() != null) {appendModuleProperty(writer, "id", activeRule.getRuleKey());}appendModuleProperty(writer, "severity", CheckstyleSeverityUtils.toSeverity(activeRule.getSeverity()));appendRuleParameters(writer, activeRule);writer.append("</module>");}private static void appendRuleParameters(Writer writer, ActiveRule activeRule)throws IOException{for (RuleParam ruleParam : activeRule.getRule().getParams()){String value = activeRule.getParameter(ruleParam.getKey());if (StringUtils.isNotBlank(value)) {appendModuleProperty(writer, ruleParam.getKey(), value);}}}private static void appendModuleProperty(Writer writer, String propertyKey, String propertyValue)throws IOException{if (StringUtils.isNotBlank(propertyValue)){writer.append("<property name=\"");StringEscapeUtils.escapeXml(writer, propertyKey);writer.append("\" value=\"");StringEscapeUtils.escapeXml(writer, propertyValue);writer.append("\"/>");}} }

CheckstyleProfileImporter 繼承ProfileImporter，checkstyle 是針對java語言的規則提供者

"Checker";private static final String TREEWALKER_MODULE = "TreeWalker";private static final String MODULE_NODE = "module";private static final String[] FILTERS = { "SeverityMatchFilter",

對于sonar plugin 如果要具有導出規則的能力，需要聲明一個類繼承BatchExtension，類BatchExtension來自于sonar-api包
