无法将 camel-http4 添加到 Eclipse 中的 Maven Camel 项目

Question

我正在尝试将 http4 添加到我的 Camel 项目中。根据文档，看起来我只需要使用 Camel 版本添加这两个 Maven 依赖项。但是我从 Eclipse 中得到一个错误：

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-http4</artifactId>
    <version>${camel-version}</version>
</dependency>
<dependency>
  <groupId>org.apache.camel</groupId>
  <artifactId>camel-http4-starter</artifactId>
  <version>${camel-version}</version>
</dependency>

但 Eclipse 报错：“缺少工件 org.apache.camel:camel-http4:jar:3.11.1”

我没有在列表中看到相关性。我尝试使用 Maven > 更新项目。我还尝试关闭并重新打开该项目。我也尝试将这些添加到另一个项目并得到同样的东西。我不确定这里有什么问题。

这是我的pom

我尝试重新索引本地存储库，并尝试使用其他一些 Eclipse 技巧来尝试刷新内容，但它们似乎没有帮助。我也试过使用 camel-http。这找到了罐子，但没有找到启动器。

    <!--  This one works -->
    <dependency>
        <groupId>org.apache.camel</groupId>
        <artifactId>camel-http</artifactId>
        <version>${camel-version}</version>
    </dependency>
   <!-- But this one still give the missing artifact error -->
    <dependency>
      <groupId>org.apache.camel</groupId>
      <artifactId>camel-http-starter</artifactId>
      <version>${camel-version}</version>
    </dependency>

Answer 1

camel-http4 已在 Camel 3.x 中重命名，您可以在 migration guide.

中找到它

原因是比 4.x 更老的 http-clients 被 Camel 3.x 删除了，所以 camel-http4 现在是唯一的，因此只是 camel-http。

Camel 2.x 中引用的内容为

<groupId>org.apache.camel</groupId>
<artifactId>camel-http4-starter</artifactId>

已在 Camel 3.x 中更改为

<groupId>org.apache.camel.springboot</groupId>
<artifactId>camel-http-starter</artifactId>

注意 groupId 中的“springboot”和 artifactId 中的“http”。
