Non-resolvable parent POM for com.example:xxx:0.0.1-SNAPSHOT

I. Description of the problem

• It is wrong when I create a spring-boot program that appears when you configure pox

Project build error: Non-resolvable parent POM for com.example:spring-boot:0.0.1-SNAPSHOT: 
Failure to transfer org.springframework.boot:spring-boot-starter-parent:pom:2.2.2.RELEASE from http://repo2.maven.org/maven2/ was cached in the local repository, resolution will not be reattempted until the update interval of repo2 has elapsed or updates are forced. Original error:
Could not transfer artifact org.springframework.boot:spring-boot-starter-parent:pom:2.2.2.RELEASE from/to repo2 (http://repo2.maven.org/maven2/): repo2.maven.org and 'parent.relativePath' points at no local POM

• The main two errors:
  • Non-resolvable parent POM for com.example:spring-boot:0.0.1-SNAPSHOT
  • repo2.maven.org and 'parent.relativePath' points at no local POM

Second, the problem is solved

• The reason is that the project can not find your pox file corresponds to version dependencies
• This is my pox Code, the problem:<version>2.2.2.RELEASE</version>

	<parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>2.2.2.RELEASE</version>
		<relativePath/> <!-- lookup parent from repository -->
	</parent>

1, a way

The Internet is more common, it is to update maven local repository, my purpose is not to write him

2. Second way

A way may not solve your problem, if not the first time you use maven, you can use this method

1. Depending on your pom file dependencies, locate the file in your local repository

<groupId>org.springframework.boot</groupId>
<version>2.2.2.RELEASE</version>

• The two package files appear in FIG red box, it can be used
  
  It is not used
  
• The pom file version into the existing version of the local
  

2. Three ways

Adapt the central warehouse bin through local address configuration, Since you can successfully updated

• After a good pom file editing, saving, local repository is automatically updated
