Why is maven compilation so slow?

Question

Always stuck at 99%. What is the problem?

Answer 1

Turn it off and use the maven command line to operate maven. Do not use it directly in the IDE

Answer 2

It’s a common problem in eclipse, but it’s not found in idea! You can also download the jar package to the local warehouse, and then specify your local warehouse

Answer 3

Modify Maven's central warehouse and let Maven download dependency packages from the domestic Alibaba warehouse, which will make it much faster.
Find settings.xml and add the following code to the mirrors tag

<mirror>
      <id>alimaven</id>
      <name>aliyun maven</name>
      <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
      <mirrorOf>central</mirrorOf>       
    </mirror>

Answer 4

This situation is usually because some files cannot be found, the download times out, etc.
