Maven SNAPSHOT不会生成快照版本

Question

I am using pom.xml with following content. I am expecting it to generate a war file with unique id, but it keeps on generating war file with name myproject-0.1.0.Build-SNAPSHOT.war .

I would like my war file to be created with unique id. Something like https://repo.spring.io/libs-snapshot/org/springframework/spring-core/4.3.9.BUILD-SNAPSHOT/ . I compared my pom file with the pom file in the folder, but could not locate much differece.

Command used:

mvn package

pom.xml file: https://codepen.io/anon/pen/gWmpZb

If you need versioned snapshots then you can get them from your managed repository following a mvn deploy .

It stores SNAPSHOTS with a timestamped version, such as

  myproject-0.1.0.Build-20170403.013619-3.war

These can normally retrieved via HTTP.

Alternatively, if you're using git and Maven 3.2.1 or newer you can do something like:

Configure your default profile in settings.xml with a property named sha1 :

<properties>
   ...
   <sha1>SNAPSHOT</sha1>
   ...
</properties>

Then you can execute maven like:

mvn clean install -Dsha1=`git rev-parse --short HEAD`

and get a locally built artifact that is versioned like:

myproject-0.1.0.Build-9b5a664.war

This is a version coupled with your last git commit .

Details of this and similar mechanisms are in the Maven 3.2.1 Release Notes .
