java - 通过ivy依赖解析下载Netty失败

转载作者：行者123 更新时间：2023-11-29 07:39:18

我正在尝试在 Ant 中使用 Ivy 来解决我的项目的依赖关系，其中之一是 Netty。

我当前的 ivy.xml看起来像这样:

<ivy-module version="2.4">
  <info organisation="foo" module="bar"/>

  <dependencies>
    <dependency org="io.netty" name="netty-all" rev="4.0.30.Final"/>
  </dependencies>
</ivy-module>

当我执行 <ivy:retrieve/> 时, 在我的 build.xml ，我得到以下输出:

download-ivy:
     [echo] Downloading ivy to /home/emichael/.ant/lib...
    [mkdir] Created dir: /home/emichael/.ant/lib

BUILD FAILED

问题似乎是 ${os.detected.classifier}没有定义。至少，这是自 https://repo1.maven.org/maven2/io/netty/netty-tcnative/1.1.33.Fork4/ 以来唯一对我有意义的事情。绝对存在并且肯定有很多 jar 。谷歌搜索 os.detected.classifier 除了指向 netty-tcnative 项目的链接外并没有产生太多结果，但似乎 netty 在其依赖项解析中使用了一些 maven 插件。它甚至有可能通过 Ivy 获得 netty，还是我做的不对？

而且，奇怪的是，完全取决于

<dependency org="io.netty" name="netty-tcnative" rev="1.1.33.Fork4"/>

解决得很好，但取决于

<dependency org="io.netty" name="netty-tcnative" rev="1.1.33.Fork4"/>
<dependency org="io.netty" name="netty-all" rev="4.0.30.Final"/>

失败。

最佳答案

问题是 Ivy 不理解 optional tag在 netty-tcnative 依赖项中(参见 parent pom)。 Maven 不会尝试下载它，如果你想要它，你必须自己添加它，然后需要定义分类器。由于 Ivy 不理解这一点，您需要将其添加为排除:

<dependency org="io.netty" name="netty-all" rev="4.0.30.Final">
    <exclude org="io.netty" name="netty-tcnative"/>
</dependency>
