尝试构建 Apache Nutch 2.3.1 时出现未解决的依赖关系错误

Question

这是我第一次尝试在 Windows 10 上基于 this youtube tutorial 设置和构建 apache nutch 2.3.1，出现如下未解决的依赖项错误：

D:\apachenutch>ant 运行时 构建文件：D:\apachenutch\build.xml 试图覆盖任务 javac [taskdef] 的旧定义无法加载 来自资源 org/sonar/ant/antlib.xml 的定义。不可能 找到了。

ivy-probe-antlib：

ivy-download: [taskdef] 无法从资源加载定义 org/sonar/ant/antlib.xml。找不到。

常春藤下载未选中：

ivy-init-antlib：

常春藤初始化：

初始化： [mkdir] 创建目录：D:\apachenutch\build [mkdir] 创建目录：D:\apachenutch\build\classes [mkdir] 创建目录：D:\apachenutch\build\release [mkdir] 创建目录：D:\apachenutch\build\test [mkdir] 创建目录：D:\apachenutch\build\test\classes

我一直在尝试使用“Ant Clean”命令和“Ant Runtime”命令，但多次失败并出现上述错误。

那么我该如何解决呢？

Answer 1

所有，由于 https: 在 Maven 下 20 年 1 月 15 日之后需要，我有以下“未解决的依赖项”错误。我能够使用正确的 https: 引用更新 ivy.xml 和 ivysettings.xml，然后构建下的错误消失了。

I hope the helps folks.

Answer 2

无法重现您的问题。

我能够使用最新的 2.3.1 候选版本成功编译代码：

git clone https://github.com/apache/nutch.git
cd nutch
git checkout -b release-2.3.1rc2 release-2.3.1rc2
ant

我是否可以建议，如果您仍然有问题，您可以针对该项目提出问题。您需要引用您要编译的版本。

Answer 3

我能够找到解决此问题的方法。就我而言，我可以通过在以下文件中将所有http 请求更改为https 请求来修复它：ivy.xml、ivy-configurations.xml 和ivysettings.xml
