Implementation of the method of re-pulling maven dependencies before SpringBoot package

When building Spring Boot projects using Maven, if you want to force pull dependencies every time you package it, you can do this by doing it.

Method 1: Force update dependencies on the command line

Executionmvn packageormvn installWhen waiting for the command, add-UParameters:

mvn clean package -U

-UThe function is to force update dependencies (Update Snapshots), make sure to re-pull the latest version of the dependency every time.

Method 2: Modify the Maven configuration file

If you want to implement it through configuration, you can use Maven'sThe following configurations are added to the file:

<settings>
  <profiles>
    <profile>
      <id>force-update</id>
      <activation>
        <activeByDefault>true</activeByDefault>
      </activation>
      <properties>
        <>always</>
      </properties>
    </profile>
  </profiles>
</settings>

Then use the following command:

mvn clean package -Pforce-update

Method 3: Update the snapshot strategy of Maven local repository

existModify the repository in the file<snapshot>Configure, force check for updates every time you build:

<repositories>
  <repository>
    <id>central</id>
    <url>/maven2</url>
    <snapshots>
      <updatePolicy>always</updatePolicy>
    </snapshots>
  </repository>
</repositories>

This way Maven checks for updates to the SNAPSHOT version every time it builds.

Method 4: Clear the SNAPSHOT cache of the local repository

Manually delete Maven local repositorySNAPSHOTThe cache of the version to ensure re-downloads every time:

rm -rf ~/.m2/repository/<your-group-id>/<artifact-id>

Things to note

  1. Frequent pulling may affect construction efficiency: Forced pulling dependencies each time will increase network request time, and it is recommended to use only if necessary.
  2. Ensure version management specifications: For the development version, it is recommended to use-SNAPSHOTSuffix, which can be automatically updated when a new snapshot version is released by the remote repository.

Overall, the easiest way is to use the command line-UParameters, which are both convenient and will not affect performance for a long time.
