question: release deploy success but snapshot failed;

error message :

Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.8.2:deploy (default-deploy) on project docker: Failed to deploy artifacts: Could not transfer artifact com.java.study:docker:jar:1.0.20211018.142205-1 from/to maven-snapshot (http://192.168.64.128:8081/repository/maven_d/): Failed to transfer file: http://192.168.64.128:8081/repository/maven_d/com/java/study/docker/1.0.20211018.142205-1/docker-1.0.20211018.142205-1.jar. Return code is: 400, ReasonPhrase: Repository version policy: SNAPSHOT does not allow version: 1.0.20211018.142205-1.

doc:

I see the official document has the following description：

Major Version Upgrade to version 3.0.0 Please note that the following parameter has been completely removed from the plugin configuration:

uniqueVersion As of Maven 3, snapshot artifacts will always be deployed using a timestamped version.

so, I want to know how to specify the version instead of using timestamped.

Answer 1

It seems your block presents error at tag :

    <version>1.0.SNAPSHOT</version>

It should be seems like:

    <version>1.0-SNAPSHOT</version>
