Today, after pulling the springboot project from gitee, I found that idea directly reported an error. The error is as follows:

Cannot resolve plugin org.springframework. boot:spring-boot-maven-plugin :

At first, I thought it was an error in the project. Later, baidu found that the default Maven configuration file and the default local warehouse address were used in the configuration of the project.

resolvent:

Open file — & gt; Settings –> Build, Execution, Deploymen –> Build Tools –>   Maven, find the user Maven configuration file and local warehouse address, and modify it to the local configuration file path and warehouse address.

Before revision:

After modification:

Refresh Maven again and solve the problem
