Question

我正在尝试将Maven依赖项从当前更改为另一个。除了一些更改之外，这个其他依赖项几乎完全提供与当前依赖项相同的功能，因为当前的依赖项是另一个版本的旧版本的分支。要做到这一点，我有：

将对pom中旧旧依赖项的所有引用更改为新依赖项
在Eclipse中删除并重新导入项目
跑maven clean install

然而，我仍然遇到与开始时相同的问题：

Eclipse没有看到任何依赖类。它甚至不提供导入它们。
在项目上尝试mvn clean package时，Maven使用以下错误消息使构建失败：

[ERROR] Failed to execute goal on project eet-demo-maven: Could not resolve dependencies for project cz.tomasdvorak:eet-demo-maven:jar:1.0-SNAPSHOT: Failed to collect dependencies at com.github.todvorak:eet-client:jar:1.3.2: Failed to read artifact descriptor for com.github.todvorak:eet-client:jar:1.3.2: Could not transfer artifact com.github.todvorak:eet-client:pom:1.3.2 from/to jitpack.io (https://jitpack.io): Not authorized , ReasonPhrase:Repo not found or no access token provided. -> [Help 1]

我已经检查过ppos的错别字和版本的正确性，所以那些应该不是问题。我怀疑这与依赖关系/依赖关系管理/ jitpack以及它们如何工作有关。我从来没有碰过他们;那里的所有内容都要么是从我为项目开始的代码中复制出来的，要么是我随后与Maven摆弄的结果，其中我几乎完全是初学者。我看了一下this问题，并在那里尝试了解决方案，但在我的案例中没有一个可以解决。

如何让Maven再次看到依赖项及其传递依赖项，并正确编译项目？

编辑：The dependency in question on GitHub

编辑2：我改变了如下的pom，我显然已经将Maven的精神安抚到了再次建造项目中。 Eclipse让我导入之前看不到的所有东西。然而，对这种突然改变的解释仍然是他的问题的一个有价值的结论。

Answer 1

依赖应该是：

<dependencies>
    <dependency>
        <groupId>com.github.todvora</groupId>
        <artifactId>eet-client</artifactId>

    </dependency>
</dependencies>

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>com.github.todvora</groupId>
            <artifactId>eet-client</artifactId>
            <version>1.3.2</version>
        </dependency>
    </dependencies>
</dependencyManagement>

你向tordova添加额外的k

Eclipse没有看到Maven依赖
