Maven 构建失败——DependencyResolutionException

Question

我正在安装一个具有 Maven 依赖项的包，并在尝试清理它时收到 DependencyResolutionException。
克隆它后，我导航到该目录并运行以下命令以安装它，没有错误:

mvn install:install-file -Dfile=./lib/massbank.jar -DgroupId=massbank  -DartifactId=massbank -Dversion=1.0 -Dpackaging=jar
mvn install:install-file -Dfile=./lib/metfusion.jar -DgroupId=de.ipbhalle.msbi  -DartifactId=metfusion -Dversion=1.0 -Dpackaging=jar

然后:

mvn clean package 

具有以下控制台输出:

如有必要，我可以发布调试日志开关的输出，但它很长。我也可以发布 pom.xml，但是它根据我的要求引用了存储库。
我搜索过类似的帖子，但似乎没有一个包含相同系列或类似的错误。有人可以帮我破译这些错误吗？
谢谢!

您不必降级 Maven。这里发生的事情是，从 3.8.1 开始，Maven 带有一个默认配置来阻止所有 HTTP(不安全)存储库。最好的方法是升级您的存储库并使其安全(HTTPS)。
但是，您可以通过将此镜像添加到您的 ~/.m2/settings.xml 来告诉 Maven 允许从您的不安全存储库下载。 :

<mirror>
  <id>insecure-repo</id>
  <mirrorOf>external:http:*</mirrorOf>
  <url>http://www.ebi.ac.uk/intact/maven/nexus/content/repositories/ebi-repo/</url>
  <blocked>false</blocked>
</mirror>

设置 blocked至 false将解决您的问题。请注意，上面的代码片段假设存储库位于 www.ebi.ac.uk镜像所有不安全的 HTTP 存储库(这就是 external:http:* 的意思)。
您还可以取消阻止单个存储库。例如，JasperSoft 存储库是不安全的，我使用以下命令取消阻止它:

<mirror>
  <id>jaspersoft-third-party-mirror</id>
  <mirrorOf>jaspersoft-third-party</mirrorOf>
  <url>http://jaspersoft.jfrog.io/jaspersoft/third-party-ce-artifacts/</url>
  <blocked>false</blocked>
</mirror>
