Question

我正在尝试使用epublib代码库。我认为我的Maven文件设置正确。依赖项确实已下载，并且位于我的.m2文件夹中。但是，我无法正确完成Maven构建。

我用过 mvn安装， mvn全新安装， mvn软件包，

如果我删除了epublib依赖项，那么一切正常。那么，在设置pom文件时我会错过什么呢？或者我可以使用其他什么方式使用epublib库。

I expect to see something like

依赖项

<dependency>
    <groupId>nl.siegmann.epublib</groupId>
    <artifactId>epublib-core</artifactId>
    <version>3.1</version>
</dependency>

不在MavenCentral中。您需要配置正确的存储库（或者，如果是拼写错误，请对其进行更正）。
