Maven compile error

1. When using maven to create a SpringBoot project, an error is reported during compilation

Plugin ‘org.apache.maven.plugins:maven-compiler-plugin:‘ not found

• It really affects the normal learning progress very much. In a fit of anger, I researched and recorded the problem thoroughly.

Error reasons and solutions

• The reason for the error is very straightforward, that is, the plugin was not found
• The first reaction is naturally that there is something wrong with the configuration of the maven settings.xml file
  • Here first determine whether the settings.xml file exists in your local path
  • If it doesn't exist, create one
  • Based on the principle of minimalism, the configuration should be as simple as possible
  • As follows ---- just configure a mirror source, simple and clear, if you need more than one, just add it

<?xml version="1.0" encoding="UTF-8"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">

	<localRepository>这里填写本地仓库路径</localRepository>
  <mirrors>

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

• After confirming that the settings.xml configuration is complete, start to refresh and download the plug-in

• At this time, it is possible to continue to report errors, and the code becomes popular, and then pay attention to the following operation
  • Add plugin dependencies in dependencies

• Pay attention to the version, sometimes if the version information is not filled in, the plug-in may not be downloaded.
  • How to check version? https://mvnrepository.com/ check here
• It can be downloaded normally here
• if still not working
  • Then go to your local warehouse path and give the folder where the warehouse is located a rightchmod 777 xxx
• What? Maybe it can't compile normally? ? ?
  • Check the basic configuration
  • 
  • Click on these places to see if they are configured correctly.
• If you still report an error? Impossible?
  • It may be a super low-level problem to report an error again. Are some letters wrong?
  • an extra space?
