So I have a project and I do regular releases to maven without a problem. I now want to make available a SNAPSHOT version of this project. So I do 'mvn clean deploy'. Everything works as you can see below:
[INFO] Retrieving previous build number from sonatype-nexus-snapshots Uploading: https://oss.sonatype.org/content/repositories/snapshots/me/soliveirajr/menta-regex/0.9.6-SNAPSHOT/menta-regex-0.9.6-20111010.153035-2.jar 5K uploaded (menta-regex-0.9.6-20111010.153035-2.jar)
I go to my sonatype manager and I can find the snapshot: 
But now when I try to use this snapshot as a dependency on some other project in another machine I get:
<dependency> <groupId>me.soliveirajr</groupId> <artifactId>menta-regex</artifactId> <version>0.9.6-SNAPSHOT</version> </dependency> Missing:
1) me.soliveirajr:menta-regex:jar:0.9.6-SNAPSHOT
Try downloading the file manually from the project website.
Then, install it using the command: mvn install:install-file -DgroupId=me.soliveirajr -DartifactId=menta-regex -Dversion=0.9.6-SNAPSHOT -Dpackaging=jar -Dfile=/path/to/file
Alternatively, if you host your own repository you can deploy the file there: mvn deploy:deploy-file -DgroupId=me.soliveirajr -DartifactId=menta-regex -Dversion=0.9.6-SNAPSHOT -Dpackaging=jar -Dfile=/path/to/file -Durl=[url] -DrepositoryId=[id]
So how do I force maven to download the SNAPSHOT version to my local (.m2) repository?

A Maven snapshot is a special version of a Maven package that refers to the latest production branch code. It is a development version that precedes the final release version. You can identify a snapshot version of a Maven package by the suffix SNAPSHOT that is appended to the package version.
The difference between a "real" version and a snapshot version is that snapshots might get updates. That means that downloading 1.0-SNAPSHOT today might give a different file than downloading it yesterday or tomorrow.
Snapshot artifacts are artifacts generated during the development of a software project. A Snapshot artifact has both a version number such as “1.3. 0” or “1.3” and a timestamp in its name. For example, a snapshot artifact for commons-lang 1.3. 0 might have the name commons-lang-1.3.
A snapshot repository is an off-cluster storage location for your snapshots. You must register a repository before you can take or restore snapshots.
Just add this to your ~/.m2/settings.xml:
<profiles> <profile> <id>allow-snapshots</id> <activation><activeByDefault>true</activeByDefault></activation> <repositories> <repository> <id>snapshots-repo</id> <url>https://oss.sonatype.org/content/repositories/snapshots</url> <releases><enabled>false</enabled></releases> <snapshots><enabled>true</enabled></snapshots> </repository> </repositories> </profile> </profiles> If you love us?
