[tycho-user] Some confusion about the deploy[-file]

[Justin Georgeson <JGeorgeson@xxxxxxx>]

For reasons into which I don’t currently wish to delve, we can’t conveniently use ‘mvn deploy’ to make our eclipse-plugin projects available in standard Maven repo for non OSGI consumers (accepting that obviously the code in those eclipse-plugin jar files can’t actually have a runtime requirement on OSGi services much list Equinox framework). I’m investigating a process to take the jar files from each milestone software site and use the deploy-file goal on them, hoping to get the result as close to having run ‘mvn deploy’ during the build. Granted these questions are about non-Tycho goals, but specifically in the context of using them for jar files packaged with eclipse-plugin  packaging type.

 

When I run ‘mvn deploy’ I end up with something like this

 

{repo}/com/lgc/com.lgc.example/1.0.0-SNPASHOT/com.lgc.example-1.0.0-SNAPSHOT.jar

{repo}/com/lgc/com.lgc.example/1.0.0-SNPASHOT/com.lgc.example-1.0.0-SNAPSHOT.pom

{repo}/com/lgc/com.lgc.example/1.0.0-SNPASHOT/com.lgc.example-1.0.0-SNAPSHOT-p2artifacts.xml

{repo}/com/lgc/com.lgc.example/1.0.0-SNPASHOT/com.lgc.example-1.0.0-SNAPSHOT-p2metadata.xml

{repo}/com/lgc/com.lgc.example/1.0.0-SNPASHOT/maven-metadata.xml

 

We have -SNAPSHOT in the pom.xml because we have to in order to have .qualifier in the manifest. The installed/deployed pom file has the correct packaging (because it’s the actual pom.xml from the build). What do those p2*.xml files provide? They look like an M2 version of a subset of a software site’s artifacts.jar and content.jar.

 

If I take a plugin jar from milestone 5  and run ‘mvn deploy:deploy-file’ with these arguments to deploy a qualified release build (m5)

 

-Dfile=com.lgc.example_1.0.0.1234.jar -DgroupId=com.lgc -DartifactId=com.lgc.example -Dversion=1.0.0-m5 -Dpackaging=eclipse-plugin

 

I end up with this

 

        {repo}/com/lgc/com.lgc.example/1.0.0-m5/com.lgc.example-1.0.0-m5.eclipse-plugin

        {repo}/com/lgc/com.lgc.example/1.0.0-m5/com.lgc.example-1.0.0-m5.pom

{repo}/com/lgc/com.lgc.example/1.0.0-m5/mavne-metadata.xml

 

If I instead use ‘-Dpackaging=jar -Dtype=eclipse-plugin’ then I correctly get a jar file. But the created pom file doesn’t set the packaging to eclipse-plugin. Does that mean that a non-Tycho build for a regular jar artifact won’t be able to specify a dependency on com.lgc.example with a type of ‘eclipse-plugin’? Does that matter? Will successfully getting the packaging type to eclipse-plugin require the presence of those two p2*.xml files?
