using github as maven repository Checksum validation failed

I've tried to use github as a maven repository for a project I host there, but I'm having some issues getting it to work. First off, here's the project:

https://github.com/dwatrous/cache4guice

I created a branch, 'mvn-repo', to hold the maven release files. I followed this process to create the maven files for that branch:

http://blog.rueedlinger.ch/2012/09/use-github-as-maven-remote-repository/

I have verified the files are up there. I then added this to the pom.xml for a project that uses the cache4guice library:

<repository>
    <id>com.github.cache4guice</id>
    <url>https://github.com/dwatrous/cache4guice/tree/mvn-repo</url>
    <!-- use snapshot version -->
    <snapshots>
        <enabled>true</enabled>
        <updatePolicy>always</updatePolicy>
    </snapshots>
</repository>

and 

<dependency>
    <groupId>com.github</groupId>
    <artifactId>cache4guice</artifactId>
    <version>0.1</version>
</dependency>

When I build I get the following errors:

And eventually this:

COMPILATION ERROR : 
-------------------------------------------------------------
error: error reading C:\Users\watrous\.m2\repository\com\github\cache4guice\0.1\cache4guice-0.1.jar; error in opening zip file

I checked and the jar file does appear to be bogus. I can't open it with a zip utility and the size is slightly larger than what is in the repository.

Any idea where I went wrong or why the file maven is getting seems to be bogus?

Solution

  • Turns out this was simple. I just needed to change the repository declaration to reference raw.github.com, like this:

    <repository>
    <id>com.github.cache4guice</id>
    <url>https://raw.github.com/dwatrous/cache4guice/mvn-repo</url>
    <!-- use snapshot version -->
    <snapshots>
        <enabled>true</enabled>
        <updatePolicy>always</updatePolicy>
    </snapshots>
</repository>

    I'm still getting a checksum issue, but all the files are downloading properly and I can build.
