java - Maven 无法解析 org.apache.velocity lib

Question

我拥有的:

我需要在我的项目中使用org.apache.velocity。因此，我将下一个字符串添加到 pom.xml 中:

<dependency>
    <groupId>org.apache.velocity</groupId>
    <artifactId>velocity</artifactId>
    <version>1.7</version>
</dependency>

问题:

但是 maven 不会将该库包含到项目的外部库中。结果，我无法使用这些类。我注意到 Maven 日志包含字符串:

[INFO] --- maven-shade-plugin:2.1:shade (default) @ id----
[INFO] Including org.apache.velocity:velocity:jar:1.7 in the shaded jar.

我尝试过的:d

• 清除本地 Maven 存储库 (.m2)
• 重建项目+所有可能的maven命令:clean install、cleancompile..等

附注

在我同事的所有计算机上一切正常。使用相同的IDE，相同的项目版本，一切都是一样的!

问题:

我可以尝试什么来解决我的问题？

Answer 1

看来你使用了maven shade插件。该插件将 Artifact 打包在 uber-jar 中，包括其依赖项，并遮蔽(即重命名)某些依赖项的包。这个 uber-jar 用于将您的包及其所有依赖项打包到一个 jar 中，从而没有外部依赖项。通过这种方式，您可以分发包，而无需关心目标中是否具有正确的依赖项。该插件附加到项目的构建阶段。您可以通过在项目的 pom 或其父项中注释其声明来禁用它。
