You can easily navigate the a Syntax Tree using LINQ. For example it is easy to get all the ClassDeclarationSyntax nodes (declared classes), that have a name starting with the letter A: var allClassesWithNameStartingWithA = syntaxRoot.DescendantNodes() .OfType<ClassDeclarationSyntax>()...

var syntaxRoot = await document.GetSyntaxRootAsync(); var semanticModel = await document.GetSemanticModelAsync(); var sampleMethodInvocation = syntaxRoot .DescendantNodes() .OfType<InvocationExpressionSyntax>() .First(); var sampleMethodSymbol = semanticModel.GetSymbolI...

If you package your application in a jar using the maven-jar-plugin or the maven-assembly-plugin, an easy way to get the current pom version is to add an entry in the manifest, which is then available from Java.
