Java Nutch 1.14失败的maven

我在构建nutch1.14项目时遇到了一个问题（在RHEL6、Java1.8上） 我已经为Maven和Java定义了env选项

但是当我执行mvn-X安装时，我有这个错误

有什么想法吗？谢谢 我已尝试删除文件夹/root/.m2/存储库，但不会影响此错误

这是FetecherThread.java中的代码错误

if (origHost.equals(newHost)) {
            LOG.debug(
                " - ignoring redirect {} from {} to {} because internal links are ignored", redirType, urlString, newUrl);
            return null;

---

因为这一行的论点是错误的

LOG.debug(" - ignoring redirect {} from {} to {} because internal links are ignored", redirType, urlString, newUrl);

---

请参阅日志框架的Javadoc以了解正确用法。

我认为当您使用带有3个字符串参数的SL4J时，API认为您需要使用以下方法：

info（标记、字符串格式、对象arg1、对象arg2）

而不是：

info（字符串格式、对象…参数）

这就是编译错误的原因

有多种方法可以解决此问题：

示例1：使用

String.format

：

LOG.debug(String.format(" - ignoring redirect %s from %s to %s because internal links are ignored", redirType, urlString, newUrl));

我不是说这是错误的，但你怎么知道这是错误的？也许解释一下会很好。是的，这是FetcherThread.java中的这一行，但我不知道它错在什么参数上，为什么？@DoNhuVy:我想你是对的。但这里实际上提供了解释：。如果用户减少日志调用中的参数数量，那么它应该可以工作。告诉我类日志的完整包名是什么。我强烈建议您扫描Maven错误输出，查看是否有更详细的错误消息。通常会对编译过程中失败的内容进行解释，例如：

…MatchFunctions.java:[31,10]；'预期

此输出已显示mvn-X安装时的唯一错误[error]/opt/NUTCH/NUTCH-1.14/src/java/org/apache/NUTCH/fetcher/FetcherThread.java:[511,17]不兼容类型：java.lang.String无法转换为org.slf4j.Marker[错误]/opt/NUTCH/NUTCH-1.14/src/java/org/apache/NUTCH/fetch/fetcher/FetcherThread.java:[522,17]不兼容的类型：java.lang.String无法转换为org.slf4j.Marker[错误]->[帮助1]您是否也尝试使用

mvn-e clean install运行过？这将提供扩展输出。@quentquont您检查过了吗？：
