Question

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，得到了Unresolved Dependencies错误，如下所示：

D：\ apachenutch＆gt; ant运行时   Buildfile：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。它不可能   找到。

常春藤探针的antlib：

常春藤下载：[taskdef]无法从资源加载定义   组织/声纳/ ANT / antlib.xml。它无法找到。

常春藤下载-未选中：

常春藤INIT-的antlib：

常春藤-INIT：

INIT：       [mkdir]创建了dir：D：\ apachenutch \ build       [mkdir]创建了dir：D：\ apachenutch \ build \ classes       [mkdir]创建了dir：D：\ apachenutch \ build \ release       [mkdir]创建了dir：D：\ apachenutch \ build \ test       [mkdir]创建了dir：D：\ apachenutch \ build \ test \ classes

清洁-lib的：

我一直在尝试使用“Ant Clean”命令和“Ant Runtime”命令仍然多次没有运气并且出现上述错误。

那么我该如何解决呢？

Answer 1

所有，由于https：在Maven下1/15/20之后需要，我遇到以下“未解决的依赖项”错误。我能够使用正确的https：参考来更新ivy.xml和ivysettings.xml，然后构建中的错误就消失了。

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版本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

如果您仍然遇到问题，我是否可以建议您针对该项目提出问题。您需要引用您要编译的版本。
