Package de.saumya.mojo.gems

Class DefaultMavenArtifactConverter

java.lang.Object

de.saumya.mojo.gems.DefaultMavenArtifactConverter

All Implemented Interfaces:

MavenArtifactConverter

@Component(role=MavenArtifactConverter.class)
public class DefaultMavenArtifactConverter
extends Object
implements MavenArtifactConverter

This is full of "workarounds" here, since for true artifact2gem conversion I would need interpolated POM!

Constructor Details

DefaultMavenArtifactConverter

public DefaultMavenArtifactConverter()

Method Details

canConvert

public boolean canConvert(MavenArtifact artifact)

Description copied from interface: MavenArtifactConverter

Returns is the artifact convertable safely into Gem.

Specified by:

canConvert in interface MavenArtifactConverter

Returns:

true if yes.

canConvert

private boolean canConvert(MavenArtifact artifact,
 String packaging,
 String extension)

getGemFileName

public String getGemFileName(MavenArtifact artifact)

Description copied from interface: MavenArtifactConverter

Returns the "regular" gem filename, as it is expected this artifact to be called as Gem.

Specified by:

getGemFileName in interface MavenArtifactConverter

Returns:

createSpecification

public GemSpecification createSpecification(MavenArtifact artifact)

Description copied from interface: MavenArtifactConverter

Creates a Gem::Specification (the equivalent JavaBeans actually) filled up properly based on informaton from POM. The "better" POM is, the getter is gemspec. For best results, fed in interpolated POMs!

Specified by:

createSpecification in interface MavenArtifactConverter

Returns:

createGemStubFromArtifact

public GemArtifact createGemStubFromArtifact(MavenArtifact artifact,
 File target)
                                      throws IOException

Description copied from interface: MavenArtifactConverter

Creates a valid Ruby Gem, and returns File pointing to the result.

Specified by:

createGemStubFromArtifact in interface MavenArtifactConverter

Parameters:

artifact - the artifact to gemize (without data only gemspec)

target - where to save Gem file. If null, it will be created next to artifact

Returns:

Throws:

IOException

relocateIfNeeded
