遵循安装指南后 Sakai 构建错误

Question

I have setup my environment for Sakai 19.0 from source following the guide on https://confluence.sakaiproject.org/pages/viewpage.action?pageId=109772882.

However when I try to build the source as detailed in 4.0 of the guide I am getting an error. Below are the logs with debug switched on:

What could I be doing wrong?

Answer 1

On January 15, 2020 the Maven Central repository disabled access through HTTP (cf. Sonatype blog ).

While recent version of Maven have the correct URL for Maven Central in their Super POM older ones might still use the HTTP URL. Upgrade your Maven installation or check whether your didn't override the Maven Central repository in your settings.xml file.

The repository configuration should look like this:

    <repository>
      <id>central</id>
      <name>Central Repository</name>
      <url>https://repo.maven.apache.org/maven2</url>
      <layout>default</layout>
      <snapshots>
        <enabled>false</enabled>
      </snapshots>
    </repository>
