当我尝试构建（mvn）幻灯片插件时，我收到错误：（见下面的详细信息）

mvn -e

Answer 1

我也得到了这个（尽管它用于akuma神器）并且可以解释原因，但还没有找到一个好的解决方案。两者都定义了父POM和新的repo：

<parent>
  <groupId>org.kohsuke</groupId>
  <artifactId>pom</artifactId>
  <version>2</version>
</parent>

<repositories>
  <repository>
    <id>m.g.o-public</id>
    <url>http://maven.glassfish.org/content/groups/public/</url>
  </repository>
</repositories>

此glassfish maven repo的URL为https://maven.glass...提供301，由于某种原因，maven决定将该响应的正文下载为POM。如果你查看~/.m2/repository/org/kohsuke/pom/2/pom-2.pom，你会看到类似的内容：

<html>
<head><title>301 Moved Permanently</title></head>
<body bgcolor="white">
<center><h1>301 Moved Permanently</h1></center>
<hr><center>nginx/0.6.39</center>
</body>
</html>

手动查看glassfish回购，我甚至没有看到所需的父POM（此时）。

我希望这会有所帮助。如果你能够弄明白，请回复，因为到目前为止这已经到了！

Answer 2

我也有这个问题，与另一个项目有不同的POM，我试图用Maven 3.X构建。简单的解决方案是安装最新的2.X版Maven。在那之后，它建好了。作为Maven新手，看来REPOS的URI格式在两个版本之间有所不同。

只需安装Maven 2.X（我使用的是2.2.1），然后将它的“bin”目录放在PATH env变量中，你就应该好了。

获取错误原因：不是v4.0.0 POM。项目org.kohsuke.stapler：maven-stapler-plugin尝试构建幻灯片插件
