Transformer Signature
Transformer services in Virgo 3.5.0 operate in terms of a directed acyclic graph of install artefacts instead of the tree which was used by Virgo 3.0.x.
If you provide a Transformer service, you'll need to rework it to implement the modified signature. For example, the WebTransformer.transform method was changed as follows:
public void transform(GraphNode<InstallArtifact> installGraph, InstallEnvironment installEnvironment) throws DeploymentException { installGraph.visit(new ExceptionThrowingDirectedAcyclicGraphVisitor<InstallArtifact, DeploymentException>() { public boolean visit(GraphNode<InstallArtifact> node) throws DeploymentException { InstallArtifact installArtifact = node.getValue(); ... } }); }
