Snapshot and maven

[Julien Dramaix]

Dear GWT lovers,

I'm trying to test the last GWT snapshot but I cannot configure maven to use it. 

I've added the following repo:

<repositories> 

    <repository> 

        <id>gwt-sonatype-snapshots</id>

        <url>https://oss.sonatype.org/content/repositories/google</url> 

        <snapshots><enabled>true</enabled></snapshots> 

        <releases><enabled>false</enabled></releases> 

    </repository> 

</repositories>

and use the following version: 2.7.0-SNAPSHOT

But Maven is not able to resolve dependencies:

Downloading: https://oss.sonatype.org/content/repositories/google/com/google/gwt/gwt-user/2.7.0-SNAPSHOT/gwt-user-2.7.0-SNAPSHOT.pom

[WARNING] The POM for com.google.gwt:gwt-user:jar:2.7.0-SNAPSHOT is missing, no dependency information available

Downloading: https://oss.sonatype.org/content/repositories/google/com/google/gwt/gwt-dev/2.7.0-SNAPSHOT/gwt-dev-2.7.0-SNAPSHOT.pom

[WARNING] The POM for com.google.gwt:gwt-dev:jar:2.7.0-SNAPSHOT is missing, no dependency information available

Downloading: https://oss.sonatype.org/content/repositories/google/com/google/gwt/gwt-servlet/2.7.0-SNAPSHOT/gwt-servlet-2.7.0-SNAPSHOT.pom

[WARNING] The POM for com.google.gwt:gwt-servlet:jar:2.7.0-SNAPSHOT is missing, no dependency information available

I've looked into the directories

https://oss.sonatype.org/content/repositories/google/com/google/gwt/gwt-user/2.7.0-SNAPSHOT/

https://oss.sonatype.org/content/repositories/google/com/google/gwt/gwt-dev/2.7.0-SNAPSHOT/

https://oss.sonatype.org/content/repositories/google/com/google/gwt/gwt-servlet/2.7.0-SNAPSHOT/

and indeed the pom files are missing.

Am I missing something ?

The repo structure is ok, your maven should download the metadata file [1] which has a reference to the last snapshot index then it should continue downloading the pom [2] and jar [3] files.

Maybe something wrong in your local repo cache, try to force updating snapshots running:

 mvn -U clean package

or removing

 ~/.m2/repository/com/google/gwt/gwt-user/2.7.0-SNAPSHOT

indeed mvn clean install -U does the trick...

Thanks Manolo

For what its worth, we use a slightly different snapshot url: https://oss.sonatype.org/content/repositories/google-snapshots/. This appears to only contain snapshots instead of releases and snapshots.

The /google/ url for whatever reason has a newer md5 and sha1 for the maven-metadata.xml file, but the dates/sizes on everything else seem to be consistent.

Right, both contain the same snapshot versions. Our jenkins CI server is pushing to the google-snapshots folder, hence some process else should be mirroring to the google one after a while, that is the reason for differences in sha1/md5. I think the best choice is to point to the url you suggest.

We should add a section on the website explaining how to install and use the snapshot.
