Pushing Jar to github when a Jenkins build succeeds - jar

Question

I have a simple Jenkins build that pulls down my project from github, builds it and reports the status of the build.
I want to have configure Jenkins to publish the resulting JAR file to a TARGET-SNAPSHOTS branch in my project.
Currently my project .gitignore's /target/*
I was looking at GitPublisher but this appears to push the entire build out, rather than just the jar file.
Thoughts on the best way to do this/if this is possible?
Thanks

Answer 1

I think you have many possibility. One of them is to run post-build script. It can be written is shell.
See Post build task
Simple script:
find . -name "*.jar" -exec scp {} user#myhost.com:/path/for/build/${BUILD_TAG} \;
Other:
Publish Over ... (ssh, ftp, cifs)

Since you're using maven and you said the github downloads section is acceptable, you can use the github downloads plugin - https://github.com/github/maven-plugins. I use this for deploying the Riak java client to our downloads section as part of the build.
In your ~/.m2/settings.xml you need:
<settings>
<profiles>
<profile>
<id>github</id>
<properties>
<github.global.userName>YourGithubUser</github.global.userName>
<github.global.password>YourGithubPass</github.global.password>
</properties>
</profile>
</profiles>
<activeProfiles>
<activeProfile>github</activeProfile>
</activeProfiles>
</settings>
Then in your project's .pom something like:
<profile>
<id>githubUpload</id>
<activation>
<property>
<name>github.downloads</name>
<value>true</value>
</property>
</activation>
<build>
<plugins>
<plugin>
<groupId>com.github.github</groupId>
<artifactId>downloads-maven-plugin</artifactId>
<version>0.4</version>
<configuration>
<description>${project.version} release of ${project.name}</description>
<override>false</override>
<includeAttached>true</includeAttached>
</configuration>
<executions>
<execution>
<goals>
<goal>upload</goal>
</goals>
<phase>install</phase>
</execution>
</executions>
</plugin>
</plugins>
</build>
</profile>
(I'm doing it as part of the install phase - you can do however you'd like)
Then simply add -Dgithub.downloads=true to your maven build -
mvn install -Dgithub.downloads=true
The web page for the plugin lists all the options for including/excluding files, etc.
