不使用spring-boot-starter-parent

Posted 2023-05-13

参考技术A 如果想不使用spring-boot-starter-parent，可以这样配置：
（1）配置使用spring-boot-dependencies

注意：一定要知名是pom import，否则会有问题。

(2)配置spring-boot-maven-plugin

注意：
(1) 如果不使用：maven-compiler-plugin，那么
a)从App.main运行不会有问题
b)mvn pacakge或者mvn spring-boot:run会出现问题：

(2) spring-boot-maven-plugin一定要配置goal为repackage，否则mvn package无法正常工作。mvn package可以正常打包，但是java -jar xxx 运行jar包会出现错误：

maven的pom.xml文件报错问题

第一次用 Spring Starter Project 创建一个Spring应用时，POM 文件报错：

 

 

Project build error: Non-resolvable parent POM for com.example:demo-1:0.0.1-SNAPSHOT: Failure to transfer org.springframework.boot:spring-boot-starter-parent:pom:1.5.2.RELEASE from https://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced. Original error: Could not transfer artifact org.springframework.boot:spring-boot-starter-parent:pom:1.5.2.RELEASE from/to central (https://repo.maven.apache.org/maven2): repo.maven.apache.org: nodename nor servname provided, or not known and ‘parent.relativePath‘ points at no local POM

 

 

解决方法：

 

参考stack overflow：

 

I‘ve also encountered a lot of error when creating a new STS project for the first time. This seems to be happen only if I don‘t have any Maven repository or haven‘t launch/use Maven before. In my case, I solve this by launching Maven command from command line manually. Try to ‘cd‘ to the project directory that contains pom.xml and call mvn that comes with STS from there.

 

cd c:\users\name\sts-projects\projectname
   c:\programs\springsource\apache-maven-3.0.3\bin\mvn compile

Then, open STS, right click on project name, select ‘Maven‘, ‘Update Project...‘ Select on ‘Force Update of Snapshots/Releases‘. Don‘t select ‘Offline‘.

 

 

即打开终端，进入出错项目的根目录，然后使用 maven bin 目录下的 mvn 编译一下，完成之后右键项目 Maven——Update Project 即可。
